The Origin of Lawns and Their Environmental Impact

“We should all know by now that lawns of green grass aren’t so “green” for the environment.”

By Linn Smith

This is an article I published several years ago, but felt it needed reiterating, as it is summer, the time most people drag their mowers out if the garage. Our changing climate requires rethinking our former habits.

Sustainable living

It’s our responsibility to change.

Lawns of the 16th century

Lawns are not a natural part of our environment. Lawns originated around the 16th century as grassy fields around English and French castles. Trees were cut down around the castles, leaving only grassy fields that would reveal an enemy coming forth in the wide open spaces. When the trees were cut, the grasses and flowers sprouted naturally, creating a meadow. “Lawn” originated from the word Launde, which means an opening in the woods. The moist climate of Europe supported these grassy meadows which eventually became our lawns of today.

The History of Grass Lawns

“Grass” is from the plant family Gramineae, which has over 9000 species of plants. In the late 16th century “grass” lawns became fashionable, rapidly catching on among the wealthy. In 16th and 17th centuries lawns were mostly wildflowers and herbs such as chamomile.

Origination of the Lawn

The castles created meadows, “lawns”, to watch for
approaching enemies.

Until the 19th century, mowing consisted of a scythe, shears for edge trimming, a gardener to maintain the lawns, and/or cattle and sheep grazing around the estates. In the 18th century this was a sign of the wealth, the vast lawn showing the amount of wealth of the owner (reminds me of Jane Austin novels)–lawns implied a staff and servants with scythes, shears and edging irons.

Mowers: Creating Easier Lawn Maintenace

In 1870 the push mower was invented, and in 1919 the gasoline mower allowed for much less effort in maintaining a lawn. (A note of interest: during World War 1, Woodrow Wilson had a flock of sheep, about fifty, cutting the White House lawn, which saved manpower during the war. He sold their wool to the Red Cross.)

When the suburbs sprouted up in the U.S. after the war, the architects created lawns around homes, which increased the value of the house and was inviting to the post war families who enjoyed lawn games of croquet, badminton, ect. In the late 1940’s and 1950’s, houses were sold with lawns already in place. With the gasoline mower and the sprinkler system, the lawns were easily maintained.

Xeriscaping

Save water with Xeriscaping

The Downside of the Beautiful Lawn

So, here’s the downside of our beautiful, European lawns today! In an article on Smithsonian.com, Sarah Zielinski says it nicely, “We should all know by now that lawns of green grass aren’t so “green” for the environment. Keeping turf from turning brown wastes water, people use too many pesticides and herbicides, toxic chemicals that contaminate the fish we eat and water we drink. And mowing burns fossil fuels, releasing greenhouse gases and other pollutants into the atmosphere. Plus nitrous oxide, a greenhouse gas, is released into the atmosphere with fertilization!”

And one more negative impact of our nice lawns–we are harming the bee population which we depend so heavily on for pollinating the wonderful foods we love! So, unless you are maintaining your lawn with only a scythe, push mower or sheep, maybe it’s time to rethink what we plant in our yards!

Overpopulation and hunger

A depletion of resources.

Xeriscaping

Xeriscaping is a water conserving method that orginated in Colorado. It originated from the Greek word “Xero”, which means dry and “Scape” meaning view. It does not mean zero landscaping. It does mean planting plants that will do well with little watering. The plants are not necessarily native to the area, but are selected for their water conserving abilities.

Xeriscaping makes more water available to the community and the environment and reduces maintenance, with just occasional weeding and mulching. Less cost and less maintenance leaves more time for other things! Xeriscaping also reduces water pollution, as herbicides and pesticides don’t end up in the groundwater.

New Mexico has been planting the most beautiful yards using water conserving plants for centuries! It’s time to rethink our beautiful lawns and think about creating beautiful Xeriscaped yards instead!

Lawns of green grass aren’t so “green” for the environment!

Global Violence Is a Symptom of Overpopulation and the Need to Limit Growth

Aristotle

Poverty and Revolution

“There are many factors which precipitate violence. Poverty and unemployment are two key ones in today’s world.”

By Dr. John J. Hidore

March 16, 2018—-Among the symptoms of global overpopulation and the need to limit population growth are widespread human health problems, resource depletion, and migration. Violence must be added to these symptoms.

Violence can be defined as the use of physical force to injure or abuse another person or persons. It also includes mental injury due to the distorting of the truth or verbal abuse. It should be pointed out that most violence does not result in death. Among the elements that most often lead to violence are: poverty, resource depletion, regional health problems, such as under nutrition, and alternative facts. These factors are often difficult to separate from one another. By far the greatest number of acts of violence do not result in death. These acts include physical assaults such as rape and beatings. Verbal abuse and threats of physical violence are also widespread, particularly. Deaths due to violence have increased in recent decades. In 2013, the most recent year for which the World Health Organization has data, an estimated 1.3 million people died from violence. Self inflicted action, or suicide, was responsible for the greatest share of the deaths, 65% of the total.

Crime and revolution

Poverty and Crime result from overpopulaton.

Violence by Individuals

Violence involving relationships between individuals accounts for another 32% of deaths. In the interpersonal death by violence, knifes and guns were the primary weapons used. The United States is the worlds leader in death by firearms. Approximately 70% of all guns privately owned on the planet are in the United Sates, mostly by men. In total numbers it is estimated there are about 300 million guns privately owned in the United States. In the last few years death by gun has passed the 30,000 mark. It now exceeds those killed in automobile accidents. Mass shootings are increasing in frequency and numbers killed. Many of these involve killing children in schools.

Overpopulation and hunger

A depletion of resources.

Group Violence

The remaining deaths were due to war between tribes or nations. In today’s world extreme violence has become global. Religion is one of the factors in group violence and tribal wars. The best known of these tribal wars is that between Christianity and Islam. However, there is violence between Islamic groups and between groups classified as Christians. The clash between Shiite and Sunni Muslims is one example. Within the major religions there are often extremist sections that promote violence such as the Ku Klux Klan in the United States and Isil in the middle east.

Contributing Factors and Trends

There are many factors which precipitate violence. Poverty and unemployment are two key ones in today’s world. The prospects for much of the population in the poor countries are not good. It should be clear that the income gap is contributing to global unrest and increased violence. Most of the increase in national wealth will go to just a few people.

One can only conclude there will be more and more violence as civil uprisings by every large numbers of people as they protest the continual decrease in income and resources available to them. It should be reiterated that the vast majority of violence does not result in death. However, the physical and mental pain that accompanies non-fatal incidents is just as real and long lasting.

The State Of The Human Species On Planet Earth

By Dr. John J. Hidore

“Undernutrition is probably the greatest health problem in the world today.”

February 2, 2018—-The human population on planet Earth has grown astonishingly fast and spread over the earth as few other species have. Global population is growing faster than at any time in history. We are now adding over 200,000 people per day to the planet. This amounts to 85,000,000 people each year.

What is astonishing is how fast the rate of growth has been increasing. It took hundreds of thousands of years for the first billion to be reached in about 1800. The last billion was added in just 12 years from 1999 to 2011. At the beginning of 2018 global population growth stood at about 7.6 billion.

Adding the billions

1 billion 1800 200,000 Years of population growth for modern humans
2 billion 1930 130 years
3 billion 1960 30 years
4 billion 1974 14 years
5 billion 1987 13 years
6 billion 1999 12 years
7 Billion 2011 12 years
8 Billion 2023-2025 12-15 years (Date estimated from various sources)

Are there enough resources for overpopulation?

With climate change will there be enough resources for all?

Food Shortages and Undernourishment

In the early 21st Century, global food production is the highest it has ever been. However, the availability of food varies greatly from place to place. Estimates of the number of people on Earth facing food shortages today vary between 800,000 and two billion. Globally, undernutrition is probably the greatest health problem in the world today. It is clear that food production and distribution is not keeping up with demand regionally, if not globally.

Undernutrition does not mean starvation. It means those suffering from undernutrition are in some way being physically affected by not getting either enough food or not getting the right kind of food. The extreme health problem is starvation.

According to data from the UN, in 2016 the number of people experiencing undernutrition grew to an estimated 815 million. Of these, approximately 200 million children suffered some form of reduced physical growth.

overpopulation

Overpopulation and climate change creates environmental stress.

Fresh Water Shortages

The absence of safe water to drink is widespread over the planet. Estimates if the number of people suffering from a shortage of safe water for drinking ranges from 600 million upwards to two billion. Over a third of the global human population now lives in water stressed regions. The ratio of population living with water related stress may increase by half by 2100. Disease is common in areas where there is no safe water to drink. Diarrhea is the most common problem resulting from contaminated water. Cholera is also prevalent.

South Sudan is one of many countries suffering from a shortage of potable water. It is estimated that less than half of the population has access to safe water. In some areas of the country women must spend an hour or more each day to get to a safe water supply and return. The trip must be made regardless of danger.

In the country of Puerto Rico, which was devastated by a hurricane last September, many residents do not have access to safe drinking water four months after the event.

At the time of this writing the city of Capetown, South Africa, with a population of four million, is faced with the possible shutoff of its water supply. Unless rains come soon this may happen within a few months. A three year drought in the watershed is responsible for the problem. How the population will react to the situation remains to be seen.

Overpopulation and violence

Overpopulation can cause world disaster.

Lack of Sanitation Facilities

Between a half billion and a billion people do not have access to a sanitary toilet facility. The majority live in Asia, but this lack of sanitation is spread over the globe, including countries such as Haiti and Mexico. In the beginning when human population numbers were small and scattered, defecating in the open was the standard. This behavior probably predominated over most of human history. It has only been in the last few thousand years that it has not been the standard. As population densities have grown it has become unacceptable. The activity became not only unsavory but unhealthy, as it became a mechanism for transmitting disease. Defecating in the open, whether in fields or vacant lots, is responsible for a many diseases and fatalities, particularly among children. Diarrhea is common among children that play in areas used for defecation. Diarrhea is estimated to kill more than 600,000 children a year under the age of five. The UN estimated that in 2016 nearly 40% children in India had stunted growth due to a combination of undernutrition and disease. The problem now is the numbers and concentration of people spreading diseases through unsanitary conditions.

That the human population has been successful on the planet is clearly evident from the growing numbers. However, while the population has grown by leaps and bounds, there has been, and currently is, much suffering by a substantial portion of the population. The number facing severe problems of survival at the current time is the greatest in history.

Inherent in this situation are two problems. One is the tremendous rate of growth of the population itself. The second is that of the uneven distribution of wealth and resources. Both the population growth rate and the unequal distribution of resources could be changed fairly rapidly, but is unlikely. It appears neither the wealthiest one per cent nor the world religions want to reduce population growth. In the last year for which data is available 82% of all income went to the richest one percent.

 Agrivoltaics: Growing Food for the Future

Agrivoltaics

Agrivoltaics: Food and Solar

“Agrivoltaics combines agriculture with energy efficiency while growing plants beneath solar panels.”

By Linn Smith

January 28, 2018—- Co-location means two or more groups, sharing the same place. Agrivoltaics, also known as Agrophotovoltaics, means using the same piece of land for solar power plus agriculture. Agrivoltaics, or solar farming, is a new way of growing plants, combining agriculture with energy efficiency while growing plants beneath solar panels.

Agrivoltaics: Dual Use of Land

In 1981, Adolf Goetzberger and Armin Zastrow developed the idea to improve overall production of crops. Dr. Goetzberger founded the Fraunhofer Institute for Solar Energy Systems in Germany. His work involved making solar an alternative to fossil fuels. In 1981, he published a paper titled, “Potatoes under the Collector,” which proposed a setup for solar energy systems in combination with agricultural land use.

agrivoltaics

Growing food with solar

Dr. Eicke Weber, Director of the Fraunhofer Institute stated, “In view of the dynamic worldwide growth of solar installations of the last decade and the increase in land usage resulting from solar installation systems, innovative concepts, like agrophotovoltaics (agrivoltaics) which facilitates the dual usage of agricultural land, help to further and accelerate the transformation of the global energy system.”

Dr. Goetzberger used the term Agrophotovoltaics or APV, as a method of harvesting the sun for both power and production of crops. APV is currently an ongoing project in Germany which demonstrates that land for both growing crops and solar electricity are compatible. Dual use of the land is resource efficient, reduces competition for land and opens up a new source of income for farmers.

The APV System

The APV system was installed on organic farmland in Germany in 2015. Approximately seven acres were used to produce crops under the ground-mounted solar panels, which were built about 5 yards off the ground. Four different crops were planted. The land in use not only generates electricity from the solar panels but is also growing food. The solar panels provide a uniform light distribution on the crops using reflection. To prove their theory, they also planted a control plot nearby using the same 4 crops, excluding the solar panels. The scientists wanted to determine which crops would grow best. Result: The crops under the APV system produced about 80% of that of the control crop. This experiment is ongoing and data will be analyzed in 2018.

Agrivoltaics: Growing food to feed the planet.

Agrivoltaics and Biosphere2

A similar experiment was being conducted at Biosphere2 when I visited several weeks ago. This research, headed by Barron-Gafford, Assistant Professor, revealed that the solar system above the crops created a warmer environment than normal when no plants were beneath , similar to the heat-island effect that happens in cities surrounded by cement and asphalt. He stated, “So think about it, if you get rid of all the plants when you put in renewables energy, you’ve gotten rid of that cooling potential… plants under the panels would allow the air to circulate and would take up carbon for photosynthesis by opening up their pores, or stomata, while letting water escape from their leaves and you get a warmer environment. We wanted to see if you put the cooling effect back into the system by growing plants beneath the solar panels, you can actually cool those panels back down and mitigate that heat island effect.”

When solar panels get too warm they start to lose their efficiency. By growing plants beneath the panels they can cool down and retain that efficiency, which makes for more renewable energy per parcel of land. The panels also shade the plants, reduce evaporation and the crops require less water to grow underneath.

agrivoltaics

Agrivoltaics

In the future, as world population grows, solar and land for food must not be in competition. The world population today is approximately 7.6 billion. Two hundred years ago it was 1 billion. At the close of the 21st century the population will be more than 11 billion. The question remains…will we be able to feed our planet’s population and meet the demand for clean energy?

Migration and Human Overpopulation

Overpopulation and violence

Overpopulation can cause world disaster.

There are a number of attributes of the human population occurring globally that indicate overpopulation and the need to limit growth”.

By Dr. John J Hidore

October 26, 2017—When the term migration comes up in conversation most people think of migration of wildlife with the seasons. For people living in the northern hemisphere, it is the migration of birds with the seasons that most often comes to mind. 

Flocks of ducks and geese moving south for the winter are common sights in some areas. The longest bird migration is that of the Arctic tern. This bird breeds in the Arctic in the summer and then flies to the Antarctic to spend the summer. The birds make a round trip of 44,000 miles.

All change is not growth

Moving Backwards

Animal Migrations

Others think of the annual migration of herds of African animals that migrate to follow the seasonal rains. The wildebeest is an example of the latter. Huge herds of these animals travel from the Serengeti in Tanzania across the Mara River into Kenya and back.

Human Migration

Humans have been migrating almost from the origin of the species. Although people in many parts of the world move in a rhythmic fashion with the seasons, human migration is not basically movement with the seasons, although some follow herds of livestock that move with the seasonal rains.

Human migration is generally applied to those people that move from one region to another on a long term or permanent basis. Often these migrants cross national borders, but many move from one part of a country to another.

Reasons For Human Migration

There are a variety of reasons that humans migrate:

1. In the past some people migrated out of curiosity. They wanted to explore. This was a viable reason why
early mankind moved about.
2. The decline of basic resources such as food or water in the homeland. There was not enough to support the
existing population, so they were searching for a more fruitful environment.
3. Some migrated to avoid the effects of natural hazards. In the 1930’s a large part of the population of New England. in the United States, fled westward to avoid the destruction caused by hurricanes. Today there is a lot of movement out of areas where recurring drought has made agriculture too great a hazard.
4. To the list must be added migration due to climate change. Migration due to climate change is not new. It has been
around for hundreds, if not thousands of years. Island people are moving to escape rising sea level.
5. Today, as in the past, people migrate to avoid violence. There was massive migration out of parts of Europe to avoid the second world war. Millions sought refuge elsewhere.

In some cases, as in Myanmar today, large numbers of people are forced to move from their homes.

overpopulation

Overpopulation and climate change creates environmental stress.

Global Migration Today

Today there is massive migration on several continents. Some of the regions and causes are:

1. Sub-Saharan Africa: Due to resource depletion, civil war, and climate change.
2. Central American: Due to civil war and poverty.
3. North America: Due to poverty and lack of opportunity in rural areas.
4. South America: Due to resource depletion and civil war.
5. In Asia: Due to resource depletion and civil war.
6. Oceania: Due to rising sea level and the increasing severity of tropical storms.
7. The Middle East: Due to war.

There are a number of attributes of the human population occurring globally that indicate overpopulation and the need to limit growth. In addition to health problems and resource depletion, current human migration must be added as a major symptom.

Resource Depletion in Today’s World

Land degradation

Overpopulation drives land degradations

“Resource depletion is evidence of overpopulation and the need to limit growth.”

By Dr. John J. Hidore

September 9, 2017—-Resources used to sustain people includes a variety of elements in the environment. Some sort of resource depletion occurs in almost all types of environments.

Land Degradation

Land degradation has become widespread. Degradation can take many forms. Among these are erosion by water, erosion by wind, and chemical degradation. On a global basis erosion by water accounts for over 50% of total land degradation. Wind erosion accounts for another 30%, and chemical degradation the rest.

Soil Erosion

Soil Erosion is devastating to food growth.

Soil Erosion

Soil has been the basis in agriculture for thousands of years. Some of the most valuable land on the planet consists of land with the best soil for growing crops.

Soil erosion consists of the removal of soil material, the transportation and deposition of the material. Soil erosion is widespread. In some areas the erosion has been, and is so bad the land is no longer usable for agriculture.

In grasslands, where most intensive agriculture takes place, soil erosion is widespread. In the drier parts of the grasslands overgrazing is common. Desertification often results. This is the reduction of the land to essentially desert conditions.

Erosion

Land degradation effects food production.

Deforestation

Deforestation is another example of resource depletion. Vast areas of the tropical rainforest are disappearing rapidly. It is being cleared for agriculture primarily. The huge band of forest in the sub-Arctic is also disappearing. In this case the timber is being cut for lumber.

With the loss of the forest cover, soil erosion becomes pervasive. These forests are important to the climate of Earth as well as a means of livelihood for people. Once these resources are reduced or eliminated, overpopulation inevitably results.

Soil Erosion

Human Activity and Land Degradation

Declining Water Resources

Of the water on the planet, almost all of it is salt water (97.5%) found in the global ocean. Only about 0.5% exists as fresh water in the rivers and lakes on the land masses. The remaining 2% exists as ice in the polar ice caps and mountain glaciers.

The rivers on the planet are extensively degraded due to agricultural and industrial chemicals, urban runoff and human waste. The addition of chemicals and organic matter entering the oceans is changing the chemistry of the water especially in estuaries.

Overpopulation and Resource Depletion

Resource depletion is a substantial factor in growing overpopulation and the need to limit growth. Even without a growing population, resource depletion is, and will continue, to lower the carrying capacity of the planet.

Resource depletion joins population growth, and declining human health as crucial global trends that are now catastrophic in some regions. Don’t let profit prohibit the drive for action that will prevent further destruction of our planet!

Global Health Problems Indicate the Need to Limit Population

Climate Change

Temperatures are steadily rising on our planet.

“There are some common symptoms of overpopulation. Widespread human health problems are one of them.”

By Dr. John J. Hidore

July 16, 2017—-At the time of this writing the global population is estimated to be about 7.4 billion. It is growing at the rate of a billion every 12 years. Earth is a finite object traveling through space with a size which is essentially fixed. An important question is whether the earth can continue to provide the resources to support a continually growing population. Limits to growth implies that there is an upper limit to the size of population a region can support.There may not be an absolute limit to growth in any region but it can still be overpopulated. The resources humans need are those things which provide food, clothing and shelter. Overpopulation occurs when the available resources cannot sustain the number of people without damage to those very resources the people depend on.

Overpopulation and violence

Overpopulation can cause world disaster.

Symptoms of Overpopulation

There are some common symptoms of overpopulation. Widespread human health problems are one of them. Among the health problems are undernutrition, dehydration, and declining resistance to disease. At present, in the early 21st Century, global food production is the highest it has ever been. However, the availability of food varies greatly from place to place. Estimates of the number of people on Earth facing food shortages today vary between 800,000 and two billion. Even if the number is that of the lowest estimate it is a significant portion of the total population.

Food shortages can result from a variety of factors. Civil wars can interrupt agriculture and interfere with the distribution of food. There are many places on Earth where this is now taking place. Syria is perhaps the best know case, but the same situation exits in many other places around the globe.

world hunger

Overpopulation depletes resources

Undernutrition is a Worldwide Health Problem

Scientific data shows that the most important factor associated with physical illness (as distinct from mental illness) is undernutrition. Globally, undernutrition is probably the greatest health problem in the world today. At this time it is estimated that more than one billion people suffer some form of undernutrition great enough to be a health problem. This is more than the population of North America and South America combined. It is clear that food production and distribution is not keeping up with demand regionally, if not globally.

Undernutrition does not mean starvation. It means those suffering undernutrition are in some way being physically affected by not getting either enough food or enough healthy food. There are a variety of types of undernutrition based on what is missing in the diet. Dietary deficiencies responsible for undernourishment include iron, iodine, vitamin A, and zinc. The extreme health problem is of course starvation.

Are there enough resources for overpopulation?

With climate change will there be enough resources for all?

Geographic Distribution of Undernutrition

The main regions where undernutrition occurs are those regions where subsistence agriculture is the predominate livelihood. This encompasses large areas of Africa and Asia. In Africa a third or more of children under the age of five years undergo growth stunting due to malnutrition. Death by starvation is most prevalent among children. Some specific areas of extensive undernutrition are in Yemen, which is in the midst of a civil war. Estimates indicate at least seven million people are undernourished. In Somalia nearly three million are in danger of severe undernourishment. In Nigeria, as a result of terrorist activity, millions of people are on the verge of starvation. South Sudan has been suffering from a long battle to obtain its freedom from the rest of Sudan and currently from tribal warfare. An estimated million children are severely malnourished with a significant portion facing starvation.

While undernourishment is largely associated with the developing countries it is found to some extent even in the most highly developed countries. The World Bank reported that in 2011 in the United States about five percent of the population was undernourished. The report also concluded that the rate in the United States had remained about the same since 1992.

Undernutrition in Children

Data for the period 2010-2016 indicates a global rate of undernutrition in children of about 23%. In parts of Africa and South Asia the rate is over 30%. Children suffer more from undernutrition than adults because of the high demand for energy and protein associated with physical growth. Some form of undernutrition affects perhaps as many as a fourth of all children. Undernourishment of a fetus and children up to the age of two can lead to a lifetime of physical and/or mental development. A large majority of these children live in developing countries.

The physical symptoms of severe undernourishment, or malnutrition, include reduce body weight or height, swollen stomach or legs, and limited energy. The most common form of malnutrition in children is kwashiorkor. It results from lack of protein and manifests itself in distended stomachs. Malnutrition is the primary cause of nearly a third of early childhood deaths.

Options to Overpopulation

There is no simple answer to the tragic developments now taking place on Planet Earth. One part of the answer is to slow, stop, or reverse population growth. Limiting population growth is an alternative to the dominant economic and political policy based on economic growth that dominates the world today. It is a viable option that would be healthy for both the human population and the planet. This part of the solution requires providing family planning to those that want it and do not now have access to it. It could be implemented almost immediately and make a difference in population growth fairly quickly. Certainly this would make an impact much faster than some other options. This would also be beneficial to women’s health. The problem is that Wall Street and many organized religions thrive on population growth and oppose any change in this direction!

Global Warming is Speeding Up

Climate Change

Temperatures are steadily rising on our planet.

“May 2015 through September 2016 were the warmest 16 months on record. The year 2016 passed the previous year as the warmest year since records began.”

By Dr. John J. Hidore

May 21, 2017—Nearly three-fourths of the earth’s surface is covered by ocean and it is ocean temperatures which control global atmospheric temperatures. Approximately 90% of the energy absorbed by Earth goes into the oceans. The other 10% is absorbed by the land masses.

In the early years of keeping weather records there was very little data available concerning the world oceans. Now there is much and the data is constantly increasing. The oceans are absorbing heat energy at a faster rate now than in the past. A recent study indicates that the amount of heat energy absorbed by the oceans has doubled since 1997. The oceans are estimated to have absorbed as much energy since 1997 as in the previous years of record.

Most of the heat added to oceans is absorbed near the surface. The actual change in temperature in the ocean surface is extremely small due to the high heat capacity of water. It takes more heat energy to change the temperature of a given unit of water than to change the temperature of air or earth materials.

The amount of energy it takes to change the temperature of a given unit of water one degree Celsius will change the temperature of a unit of dry air by four degrees. The same amount of energy will change dry land by about five degrees. This helps explain why the atmosphere and bare land get so hot.

Planet Earth is warming.

Record temperatures around our planet.

Evidence of Global Warming

The majority of people, including both scientists and non-scientists around the world, understand that our planet earth is warming. There is overwhelming evidence that this is the case. Geological evidence indicates that the earth is now the warmest it has been in the last 650,000 years. Data also indicates the 20th Century was the warmest century in the past 1000 years.

The year 1880 marks the beginning of the modern historical record. Analysis of the collected data indicates the temperature on the planet has been increasing rapidly in the years since the global record was established.

The number of weather stations collecting temperature data has increased rapidly with time. There are now more than 6000 sites where data is being collected. Satellites are now also contributing data.

Global warming

Records are being broken around the world.

Global Temperatures for the 21st Century

Since 2000 global monthly temperatures have broken records more than 30 times. The average global temperature has increased about 0.8ºC (1.4ºF) since 1880. About 2/3 of this increase has been since 1975. Most of the warmest years on record have occurred since the beginning of the year 2000. It is significant, that in comparison to all the record warmth, the coldest year on record was more than one hundred years ago in 1911.

Record Temperatures Since 2000

Regions where record high mean annual temperatures occurred since the beginning of the year 2000 are:

Africa, 7 countries
Antarctica Asia, 21 countries
Europe, 23 countries
North America, 4 countries
Oceania, 2 countries
South America, 5 countries

Global Warming: 2015 to Date

The year 2015 was the warmest year on record up to that date. The mean temperature was 14.7 ºC (58.62degrees F). This was 0.9 ºC (1.62degrees F) above the mean of the 20th Century and 0.2 ºC (0.29degrees F) over 2014. It was the largest annual temperature increase on record. All months in 2015 set new records with the exception of January and April. December of 2015 was unusually warm, even for 2015. It was more than one degree Celsius warmer than the 30 year normal. Climate normals are set by 30 year intervals. The current normal is the period from 1981 to 2010.

Fossil Fuels

Coal and Oil Formation

Record Breaking Temperatures

Many global temperature records were recorded in 2015 and the trend continued into 2016. February 2016 continued a string of nearly a dozen straight months of record monthly temperatures. The winter season, December through February, was also a record.

In February 2016 global temperatures were not only record temperatures, but they rose drastically. The increase over the previous year was also the most since records began in 1880. May 2015 through September 2016 were the warmest 16 months on record. The year 2016 passed the previous year as the warmest year since records began. July of 2016 was the warmest month ever recorded since 1880.

Indian Heat Wave of 2016

India experienced extreme high temperatures in the spring of 2016. In May a severe heat wave alert was issued for several states. A severe heat wave is one in which temperatures of at least 47.2°C (117°F) occur.

In the city of Philodi, in western India, unofficial temperatures reached 51°C (124°F). This is the highest temperature on record in India. Temperatures averaged above 40°C (104 ºF) over large areas. Some urban high temperatures were:

New Delhi 47 °C (117 ºF)
Churu 50 °C (122 ºF)
Philodi 51.°C (124 ºF)

Global Warming and Population

High temperatures in India had a huge effect on the human population. The impact on the country was immense. More than 300 million people were adversely affected. Crops failed or were below average in 13 states in during the growing season. Thousands of farmers abandoned their farms. Approximately 17,000 villages had, or were facing water shortages. Several Indian states shut down schools to reduce risk to students. Heatstroke was a widespread problem and many deaths were reported across the region. It has been classified as one of the deadliest heat waves in modern history.

The Hazards of Extreme Temperatures

It needs to be understood that temperature numbers are just a measure of atmospheric heat. What is truly important is the impact of the greater heat. Record high temperatures affect almost all living things in the region where they occur. What future temperatures will be is unknown. Since record high temperatures are occurring more and more frequently it seems highly probable that new and more frequent high temperature extremes will occur and that the effects will become more hazardous to life on the planet. The only real solution to the problem is to reduce the emissions producing the warming and curb population growth.

The Symptoms of Over-population and Limits to Growth

Overpopulation and violence

Overpopulation can cause world disaster.

Even a cursory examination of the world today indicates there is a major problem of overpopulation by the human species.

By Dr. John J. Hidore

May 1, 2017—At the time of this writing the global population is estimated to be about 7.4 billion. It is growing at the rate of a billion every 12 years. Earth is a finite object traveling through space with a size which is essentially fixed. An important question is whether the earth can continue to provide the resources to support a continually growing population. Limits to growth implies that there is an upper limit to the size of population a region can support. There may not be an absolute limit to growth in any region but it can certainly be overpopulated. The resources humans need are those things which provide food, clothing and shelter. Overpopulation occurs when the available resources cannot sustain the number of people without damage to those very resources the people depend on. There are some common symptoms of overpopulation.

Hunger

Overpopulation can devastate the world’s food supply.

Human health problems

Among the health problems are undernutrition, dehydration, and declining resistance to disease. Globally undernutrition is probably the greatest health problem. At this time it is estimated that nearly a billion people suffer some form of it. This is the equivalent of the population of North America and South America combined. Undernutrition does not mean starvation, but that the people in question are in some way being physically affected by not getting either enough food or not getting the right kind of food. Starvation is the extreme case. There are a variety of types of malnutrition based on what is missing in the diet. Essentially malnutrition is the imbalance between the body’s need for nutrients and energy and what the body is actually getting. Another billion do not have fresh water for drinking.

An untold number are suffering from disease related to health problems. Scientific data shows that the most important factor in experiencing physical illness (as distinct from mental illness) is undernutrition. When people are undernourished the probability of getting an infectious disease increases significantly. Children suffer more from undernutrition than adults because of the high demand for energy and protein associated with physical growth. Some form of undernutrition affects as many as a fourth of all children. A large majority of these children live in the developing countries. The most common form of malnutrition in children is kwashiorkor. It results from lack of protein and manifests itself in distended stomachs.

Overpopulation depletes resources

Resource Depletion

Resources used to sustain people include a variety of elements in the environment. Some sort of resource depletion occurs in almost all types of environments. Land degradation has become widespread. In grasslands, where most intensive agriculture takes place, soil erosion is widespread. Soil has been the basis for agriculture for thousands of years. Some of the most valuable land on the planet consists of land with the best soil for growing crops. Soil erosion is widespread. In some areas the erosion has been and is so bad the land is no longer usable for agriculture. In the dryer parts of the grasslands overgrazing is common. Desertification often results. This is the reduction of the land to essentially desert conditions.

Deforestation is another example of resource depletion. Vast areas of the tropical rainforest are disappearing rapidly. It is being cleared for agriculture purposes. The huge band of forest in the sub-Arctic is also disappearing. In this case the timber is being cut for lumber. With the lost of the forest cover soil erosion becomes pervasive. These forests are important to the climate of Earth as well as a means of livelihood for people. Once these resources are reduced or eliminated overpopulation inevitably results. With land degradation and deforestation animal species are also disappearing. Animals of all variety provide food, and clothing, and other items. There is currently a global demise of species taking place so great that it is being referred to as a mass extinction.

A depletion of resources.

Migration

Human migration is the movement of people from one location to another. It can be from one part of a country to another or across national boundaries. It can involve individuals or numbers in the thousands or millions. The human species has engaged in migration nearly as long as the species has existed on Earth. Present consensus is that the earliest humans developed in an area of East Africa known as as Olduvai Gorge in what is now Kenya. The species spread out from there in all directions. It moved southeast through the open forests into what is now the country of South Africa. Later the species spread north and east across the middle east and all the way to Australia, Asia, and the Americas.

People migrate for a variety of reasons. In the past people may have migrated out of curiosity. A more likely reason is the search for more abundant resources. The massive wave of migration in Europe and the Middle East at the moment is the greatest since the period just before and during world War II. The world is now focused on this current migration due to the problems it is creating. Some of the migration is an attempt to move from areas suffering from overpopulation and a shortage of resources. Another portion is to escape violence in their homeland. Declining employment opportunities is another force driving migration. No continent is exempt from problems due to migration. An influx of large numbers of people into any region can generate major problems. The building of wall, fences, and moats came into existence by groups of people to keep migrants out of their territory.

Violence

It is predictable that when overpopulation occurs, in some cases at least, there will be violence among individuals and groups. Tribalism, indigenous uprisings and terrorism become predictable. Violence among groups may be along ethnic lines, economic status, or political power. Violence has become pervasive around the world as competition for resources increases. Personal violence is epidemic in many cities and countries.

Indigenous uprisings are violent acts by people native to an area. Indigenous uprisings by tribal people have occurred throughout history and on every continent when an external population becomes too oppressive. Many such uprisings have occurred around the world as Europeans moved to take over land used by the people originally occupying it. Such uprisings are now forcing governments to recognize the native people as a political force.

Terrorism is what appears to be a random act of violence, usually directed against groups of people. It almost always involves the killing of unsuspecting people. It is usually carried out to serve the purpose of those committing the act. It can be directed against a political group, a government, religion, or other group. It has been engaged in by individuals, groups, and even governments. These acts of violence are often done in a spectacular fashion so as to attract attention to the perpetrators. Revolutions are an example of violent reaction to government policies

Population Growth: Limited or Uncontrolled

Even a cursory examination of the world today indicates there is a major problem of overpopulation by the human species. There are examples everywhere. Is it possible that the entire planet has reached this stage? If this is the case there are options. We can foster a population in which there is less undernourishment, less massive migration and less violence. Limiting population growth is an alternative to the dominant economic and political policy of economic growth. It is a viable option that would be healthy for both the human population and the planet. The alternative is to allow uncontrolled growth of the population and increase the hazards to all.

Overpopulation Results in Global Stress

Are there enough resources for overpopulation?

With climate change will there be enough resources for all?

Climate change can decrease the carrying capacity of a region.

By Dr. John Hidore

February 23, 2017—The human population has been growing in size and spreading out over the planet ever since its origin in Africa long ago. It is currently growing faster than at any time in history. Today it is equivalent to adding the populations of the earth’s three largest metropolitan areas each year…or between 80 and 90 million people every 12 months. Various estimates place the global population at between seven and seven and a half billion. Of this two billion has been added in just the last 24 years.

Overpopulation Defined

There are a number of concepts being used today in relating the size of the human population to the environment. These are population growth, limits to growth and overpopulation, and they are each related. The basic resources people need are food, water and essentials for clothing and shelter. Ideally, in any region the size of the human population remains below or in balance with the resources available to support it. When in balance it results in the population being sustained for long periods of time. However, we do not live in an ideal world and the sustainable population seldom exists.

Population growth in any region may result in the area no longer having enough resources to sustain the growing number of people at a healthy level. When this occurs either the people, the environment, or both become stressed. The symptoms of population stress include human health problems, resource depletion, migration, and violence. Environmental stress includes a variety of processes, including deforestation, soil erosion and climate change. In any event when human stress or environmental stress takes place the region is overpopulated.

Carrying Capacity and overpopulation

What is Carrying Capacity?

Processes That Create an Unsustainable Population

Even if the population in a region stays fairly constant it can become overpopulated by environmental changes. Climate change can increase the number of people a region can support. Rainfall may increase in a dry region, or temperatures may get warmer or cooler to favor plant growth.

Carrying capacity is the number of organisms a region can support without environmental degradation. Climate change can decrease the carrying capacity of a region. During the last ice age, large areas of what are now dry lands or deserts received more rainfall than they do now. The Sahara Desert and much of the middle east contain the remains of cities that flourished during wetter times, but are abandoned now due to climate change.

Changes in technology can also change the carrying capacity. As technology has progressed through time many regions have been able to support an increasing number of people. However, the effect of technological change tends to be short-lived and ultimately encourage overpopulation. Even with a more favorable climate and the addition of technological advances there is still a limited carrying capacity and overpopulation can occur.

The green revolution of the 20th Century is a good example of how the carrying capacity can be increased. Modifying plant species allowed crop production, particularly grain, to greatly increase and feed a growing population. 

Just as humans can increase the carrying capacity they can also decrease it. Over-grazing by livestock, soil erosion, salinization of soils, deforestation, or human induced climate change can reduce the carrying capacity. This lowers the level of the sustainable population so that overpopulation occurs.

Overpopulation: The Big Question

The big question, “Does overpopulation occur regionally or globally?” Clearly on a regional basis the answer is yes. All the symptoms are there. Whether it is occurring on a global basis in today’s world is not clear. There are symptoms of overpopulation on every continent except the Antarctic.

Many scientists say the evidence of overpopulation is severe. For example: more than a billion people are undernourished. Another billion do not have clean water to drink.

 Climate change is taking place at an astonishing rate. The extinction rate of plant and animal species is the highest in recorded history. It may be that the resources available to us will support a population of only half what it is at the present time. If the latter is the case, immediate, and perhaps extreme, measures must be taken if world stress and turmoil is to be avoided!

The evidence of overpopulation is severe!
