On Population Growth

“The momentum for an increasing population seems to be difficult to change.”

By Dr. John J. Hidore

March 17, 2019—–During the earliest stage of modern humans the human species was struggling with the environment. They were just beginning to use stone tools. The size of the population was limited by the amount of wild food that could be gathered or caught. When food was scarce the population died back, and when it was plentiful the population expanded.

Diseases due to technological advances began at an early time. Sinusitis is a disease that irritates the nose as a result of breathing damp, smoky, or dusty air, such as was often found in inhabited caves. Evidence of sinusitis has been detected in skulls dating well back into the paleolithic. Only limited numbers of human lives were lost from storms and other short lived events as the population was small and widely scattered.

Overpopulaton

Overpopulation and turmoil leads to current migration patterns.

During the first 500,000 thousand years the population growth was slow. Birth rates were high, perhaps between 38 to 42 per thousand. The death rate was also very high, perhaps between 35 to38 per thousand. Evidence indicates that infant mortality was high and average life span was around 30 years.

Although life was difficult for hominoids during this time, the human species triumphed. Charles Darwin stated the case for these early people. “Man, in the rudest form in which he now exists, is the most dominant animal that has appeared on earth. He has spread more widely than any other highly organized species, and all others have yielded before him.” (1871)

Current and projected Growth

The global population numbers began to grow and are now growing faster than at any time in history. We are now adding about 224,000 people per day to the planet. This adds 82,000,000 people to the planet each year. That annual increase is the same as adding the population of the United States to the planet every three to four years.

What is astonishing in the growth data 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 time it has taken for adding each billion has dropped rapidly. The last billion was added in just 12 years from 1999 to 2011. At the beginning of 2019 global population stood at about seven billion. The key element in driving population growth is changing technology which has increased the global food supply.

Some estimates of early human population size:

125,000 1 million years ago
1-5 million 11,000 B.C
50 million 3,000 B.C
500 million 1,500 A.D.

Adding the billions Time Span for the growth:

1 billion 1800 200,000 to a million years
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 12-14years

The human population reached its highest annual growth rate of about 2 percent per year, in the early 1970s. The growth rate in 2018 was around 1.1 percent. While the rate has dropped the absolute number of humans added to the planet each year continues to be greater than in the past. In mid-2019 the total population is estimated to reach about 7.7 billion.

Carrying Capacity and overpopulation

What is Carrying Capacity?

Region Growth

Today the fastest-growing countries are the developing countries. Many of the nations with the highest growth rates are in Africa and southwest Asia. China has the largest population of any country. However, India, which has a smaller population than China but has a higher growth rate, is adding 1/3 more people each year than is China. The UN projects India to surpass China as the most populous country in the world about the year 2028. At that time both countries will have a population of about 1.45 billion. China’s population will begin to stabilize near that time and India’ will continue to grow for some time. Most of the growth will be in developing countries with more than half in Africa. Population in Sub-Saharan Africa is projected to double from the 2010 population of 0.86 to 1.96 billion in 2050.

Are there enough resources for overpopulation?

With climate change will there be enough resources for all?

Prognosis

The next billion people added to the earth will want and expect food, clothing, shelter, and some means of employment. How are these needs to be met? There are already a billion people with some degree of malnutrition. Most of the population supports themselves from agriculture. All good and even marginal land is already occupied, and much productive land is being removed from agriculture due to erosion and general depletion. How are these agriculturists going to find employment? These are critical issues.

The momentum for an increasing population seems to be difficult to change. Global business thrives on population growth. It seems the options are limited. Either the human species understands what is taking place and mandates a change, or these trends will continue until some unpredictable apocalypse eliminates a substantial portion of the people living at the time.

The Symptoms of Over-population at the Beginning of the Year 2019

Aristotle

Poverty and Revolution

“Can the earth continue to provide the resources to support a continually growing population?”

By Dr. John J. Hidore

Introduction

At the time of this writing the global population is estimated to be about 7.7 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.

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 perhaps 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.

Sustainable living

It’s our responsibility to change.

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. 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 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, 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.

Overpopulation and wallstreet

Does organized religion support overpopulation?

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 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 just 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 to go around. 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. In the United States Mr. Trump is demanding five billion US dollars to build a wall along the border between the United States and Mexico. Because the US Congress has not provided that money, the government shut down. Now thousands are out of work and many government agencies have ceased to function.

Carrying Capacity and overpopulation

What is Carrying Capacity?

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. In the United States an emerging atrocity is school shootings.

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 random acts 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 another 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

Do these symptoms of overpopulation and limits to growth actually occur?
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 decrease the welfare of all but a few.

CLIMATE CHANGE, DROUGHT AND FAMINE

Some species may become extinct

The growing ranges of our food supply will change as the temperatures rise.

“Climate change is the current cause of drought and famine.”

By Dr. John J. Hidore

December 10, 2018—There are many causes of famine, but one of the major ones is drought. Most of the past catastrophic famines have been precipitated by drought resulting from short term shifts in the atmospheric circulation.

Crop Yield and Drought

Drought generally occurs when there is a short-term lack of precipitation lasting more then one growing season. They are the most common in regions which have a pronounced seasonal rainfall regime. Drought affects the quality and quantity of crop yields and the food supply for domestic animals. During severe droughts there may be a great loss of domestic animals. The loss of milk products or meat increases the impact of drought.

Climate Change

Our Food Supply may be Rapidly Reduced with Rises in Temperatures.

Great famines have occurred throughout the Asian continent from the time that agriculture spread over the continent. China, India, Russia, and many middle-east countries have suffered frequently from famine resulting from drought. A famine is described as occurring during the time of Abraham, about 2247 BC. A massive famine occurred in Egypt prior to the exodus of the Israelites.

Drought and famine are endemic in India and China. The oldest record of famine in India goes back at least to 400 B.C. and in China to 108 B.C. From the time of the earliest known famine there have been nearly continuous episodes of drought and famine in some part of the region. Other regions experience droughts as well. It should be mentioned here that what is often referred to as The Great Famine occurred in Europe in the period from 1315-1317.

Eighteenth Century Drought and Famine in India

In the mid-eighteenth century the people of India were largely subsistence farmers. It was primarily crop agriculture based on the whims of the monsoons. The country was under the control of the British East India Company, which kept the farmers on the verge of starvation under the best of conditions. Because of the general poverty of the masses and the marginal nature of the food supply, only a small shortfall in the crops in a given year produced scattered starvation. India is a huge country, and at the time only a ponderous transportation system existed. There was no means of moving large quantities of food, nor of moving large numbers of people to areas where food was available. When drought set in there were few alternatives to starvation available.

Drought and Famine: 1768

In the summer of 1768 there was little rain and crops were poor. The drought continued into 1769. Famine was apparent in the northern parts of Bengal by November 1769. By April 1770 over 30 million people in West Bengal and Bihar were affected. Fatalities were estimated at upwards of 10 million. The deaths were the result of both starvation and disease. Smallpox became epidemic along with the drought. The death toll from this famine is the highest known from any famine up to this time.

Famine has often been a problem in some part of the world since this event. As with this one, short term climate change has been the primary cause.

Climate Change: Investing in Education for Girls


“Early marriage of girls, because of drought and extreme weather, forces them to stay in existing conditions of poverty.”

Drawdown

Global warming and educating girls.

By Linn Smith

October 25, 2018—-What does educating girls have to do with climate change? According to a book called “Drawdown” by Paul Hawken, educating girls is a climate solution which could save 59.6 gigaton (millions of tons) of CO2 in our atmosphere by 2050.

Hawkins says that in many countries such as Africa, girls marry early, which extends the length of childbearing years. More than 700 million girls worldwide today have married as children. In countries where drought, flooding and extreme weather have affected resources, to ease the burden on families and collect the dowries, girls are married as children. So it’s a circle of devastation for our planet. Girls marry because of climate extremes which perpetuates climate change with population increases!

Drawdown

Education and family planning decreases the effects of climate change.

Ending Child Marriage

The following excerpt is from the article, “Ending Child Marriage in Africa” by Annerieke Smaak, “This man went to my uncles and paid a dowry of 80 cows. I resisted the marriage. They threatened me. They said, ‘If you want your siblings to be taken care of, you will marry this man.’ I said he is too old for me. They said, ‘You will marry this old man whether you like it or not because he has given us something to eat.'”

Girls give up school in drought conditions, staying home to carry water long distances or help find food for the family. Hawken states, “In Malawi, some people estimate 30-40% of child marriages are due to poverty caused by flooding and drought due to climate change.”

climate change

Education and family planning for girls

Reproductive Choices for Women

Educating women in reproductive choices will help tackle birth rates by improving lives when we make families secure with necessary resources. Supporting girls education is a positive investment benefiting the family, community, planet, and the girls themselves.

Educated women have smaller families. Data shows that girls with 12 years of education or more will have 4-5 fewer kids than girls with little or no education. This directly effects a country’s economy as failure to educate can cost the global economy 15-30 trillion dollars.

Hawkins states “The exact dynamic between family planning and girls’ education is impossible to determine, but our models allocate 50% of the total potential impact to each….by funding education and family planning it would close an annual financing gap of $39 billion to lower income counties for implementing these solutions.”

Hawkins Drawdown

Early marriage leads to more children.

Early Marriage and Climate Change

Finally, Christina Wauk and Amanda Braga state, “Early marriage of girls, because of drought and extreme weather, forces them to stay in existing conditions of poverty, vulnerability and marginalization that perpetuates low-skill development. Climate change increases peoples’ vulnerability to the shocks of weather related disaster and exuberant existing gender inequalities that obstruct opportunities for a girl’s social and economic empowerment.”

Educating and family planning for girls in lower socio-economic countries is one of the many solutions we need to look at in alleviating future climate destruction!

Refugee Population Explodes

“What the future is for global refugees is unknown.”

Overpopulaton

Overpopulation and turmoil leads to current migration patterns.

By Dr. John J. Hidore

September 21, 2018—–Refugees are a particular group of migrants. Refugees are people fleeing violence or being forced to move by violent groups and cannot safely return. Refugees have often been subject to practically every form of physical and mental abuse known to the human species. They include beheading, burning alive, and rape. Most refugees leave their home country but a large portion move from one part of their home country to another. Most people become refugees for being a part of a group of people that are disliked or hated by another group, which is often a larger group.

The refugee group may be identified on ethnic, religious reasons, or simply despised for economic reasons. An example of an economic basis might be a group of people that controls most of the good agricultural land. Many people have become refugees due to internal problems within their countries. South Sudan is one such country. More than 2.5 million people have, or are seeking safety outside their own country. The problem in the country is the struggle for power between different tribes.

Global Distribution of Refugees

There are refugee groups in North and South America, Europe, Asia, and Africa. Perhaps the best known group of refugees today are those in the Middle East, particularly in Syria where the number of refugees from the civil war numbers in the millions. The United Nations estimates the total number of global refugees at more than 65 million. The number of refugees crossing national boarders is estimated to be more than 25 million.

By continent the numbers of refugee believed to exist are:
Africa, 6.6 million
Europe 6.1 million
Middle East & North Africa:2.6 million
The Americas: 480.000 .

By country the five countries which have contributed the most refugees are:
Syria: 6+ million
Afghanistan: 2.6 million
South Sudan: 2.4 million
Myanmar: 1.2 million
Somalia: 0.9 million (World Vision Star)

Refugee Camps

Scattered throughout the regions where refugees have escaped to are large refugee camps. A refugee camp is an area controlled by a government, national, or international agencies. A camp is constructed as a temporary featyre and the services are also provided on a temporary bases.

Worlds 10 largest Refugee Camps (Source: Raptim.org}
1. Kutupalong in Cox’s Bazarr, Bangladesh 885,000+
2. Bidi Bidi: Northwest Uganda 285,000
3. Dadaab Refugee complex: Kenya 235,000
4. Kakuma : Kenya 184,000+
5. Nyarugusu Kigoma Tanzania 139,000+
6. Jabaliea: Gaza Strip 119,000+
7. Zaatari: Jordan 80,000+
8. Yida: South Sudan 70,000+
9. Katumba: Tanzania 66,000+
10. Pugnido: Ethiopia 53,000 +

What the future is for global refugees is unknown. However, based on economic policies that exist around the world today and the growing global population it would quite reasonable to see the numbers rise.

Irrigation and Water Depletion in the Southwest United States

Water depletion

Irrigation in the Southwest U.S.

“We need to work together to feed the world, but we also need to work together to save and monitor our water resources.”

By Linn Smith

August 26, 2018—- On the farmland of my youth in the Midwest, my brothers and I spent much time baling hay for our cattle, but water was plentiful and plants thrived with no irrigation. Cows were in green pastures in the summertime and in winter months we fed hay when grasses died.

Farming in the Southwest

When traveling to southern New Mexico and southern Arizona, I often see hay and cotton fields in the middle of the desert and semi arid terrain. It seems an unlikely place to grow crops that have high water needs! 

Today the Southwest is water-stressed with many lawsuits taking place, both privately and between states, over water rights. The projection is that reduced precipitation by mid-century will result in reduced runoff into the water basins that feed irrigated fields.

I recently heard a local resident from Arizona say that Saudi Arabia was buying land in Arizona and California’s arid landscape for growing hay and shipping it back to their country. The export of hay (grasses grown for feeding animals) is booming in the U. S., with the amount of hay leaving the west coast ports increasing yearly. In 2017, the total exports of alfalfa and other hay reached 4.2 million metric tons and is continuing to grow.

The fact that hay and cotton are being exported is healthy for our economy, as many U.S. farmers are growing and exporting this commodity, mostly from states that require little irrigation for agriculture. The issue is growing crops in the desert Southwest in what is fast becoming an area where water is not replenishing itself in the rivers and reservoirs.

The Colorado river

Farmers in the Southwest are left little water for irrigation.

Depletion of our Water Resources

What is healthy for our aquifers and rivers when they are not replenishing? Doug Kenny, Director of the Western Water Policy Program at University of Colorado, says about potential water shortage. “Right now, it’s the effort to maintain the levels of water stored in the big reservoirs, Lake Mead and Lake Powell. They’re about half full, which is about as low as they can go before mandatory cuts in water deliveries. It’s a math problem—managing water coming in vs. water going out. So far this century, people have pulled more water out than consistently flows in. That has to change.”

Saudi Arabia and the Southwest

 Most crops will only thrive with irrigation in the arid Southwest.  Saudi Arabia is confronting a major depletion in its aquifers which has brought its wheat and hay production to a halt. They have bought 1,000’s of acres in arid parts of the U.S., Arizona and Southern California (and several other countries), allowing them to take advantage of the U.S. water laws. The Laws of the Colorado River are currently under scrutiny by the Upper and Lower Basin states because of continuing depletion of the river and Lake Mead, which supplies water to the lower Colorado river basin states. Most crops will only thrive with irrigation in the arid Southwest.

The drought of Southwest U.S.

Lake Mead depletion

Southern California: Irrigating Crops vs Urban Use

In Southern California the Metropolitan Water District pays landowners to fallow their land, letting it lay without planting crops so that water is freed up for urban areas. Since 2005, over $200 million has been paid to farmers not to grow crops on this program. This allows water to be directed to Los Angeles and other cities in Southern California.

Has this program enabled corruption and profit from drought conditions? A single recipient, Fisher Ranch, owned by a board member of the operation, has received over $27 million a year since 2005 for leaving his land fallow.

Depletion of water for crop irrigation

The Water Crisis

As I continue to study depleting water conditions in the Western U.S., I realize in 20 years, if not sooner, we are going to be facing a water crisis due to climate change and over allotment of water rights and usage. We need to ask ourselves what changes are necessary today to alleviate the impending crisis.

Water shortage is going to be a complex problem in the future requiring many people to make sacrifices. We need to work together to feed the world, but we also need to work together to save and monitor our water resources. Education and awareness is a place to start.

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 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.

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 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.

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?

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.

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!
