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)

Overpopulation and wallstreet

Does organized religion support overpopulation?

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 world’s increasing population!

Cities: Combating Climate Change and Pollution

Working toward 100% renewables

Working Toward Renewable Energy

“Innovative thinking must solve our current and future climate and pollution problems as cities grow, and individuals must do their part in leaving a planet that future generations can comfortably occupy!”

By Linn Smith
January 26, 2019—I live part of the year in a city that is rapidly growing. Along with this growth comes air pollution, traffic congestion, increased construction and industrial businesses which spew toxins into the air as they burn fossil fuels. Gone are the days of vacant lots, laid back life styles and traveling anywhere in the city or suburbs in under 20 minutes. Now every hour of the day looks like rush hour!

Plans to combat this city’s growth include expanding the transit system, which has greatly fallen short, as many times it’s down or not functioning at full capacity. There is a great need for more innovative solutions!

Rapidly Expanding Cities

According to UN Habitat, cities consume 78 per cent of the world’s energy and produce more than 60 per cent of the world’s greenhouse gas emissions. Yet, they account for less than 2 per cent of the Earth’s surface. It’s predicted that 2/3 of the world’s population will live in cities by 2050.

Urban Heat Islands

As temperatures increase due to climate change, urban heat islands will be created by concrete and buildings holding in the heat. (See, https://planetearth5.com/?s=urban+hot+spots). As I wrote in this article, “If you live in a city you probably have noticed how much cooler it is in the summertime when you take a drive in the country. Drive back toward the city, with its concrete buildings, and you feel the great intensiveness of a hot summer day. There’s a name for this city heat….the Urban Heat Island Effect. An Urban Heat Island describes a large area of buildings and concrete (cities) that has temperatures which are higher than the countryside surrounding them. According to http://www.epa.gov, “ ‘The annual mean air temperature of a city with 1 million people or more can be 1.8–5.4°F (1–3°C) warmer than its surroundings. In the evening, the difference can be as high as 22°F (12°C).’ ” With global warming the temperatures of the heat islands will continue to increase.”

building green

Cities, states and individuals must do their part in preventing climate change.

Cities, Health and Pollution

Pollution, a by-product of urban living, is also linked with climate change. Both climate change and air pollution are a direct result of burning fossil fuels, which increase CO2 emissions causing the greenhouse effect in our planet’s atmosphere. The Energy Policy Institute in Chicago found life expectancy is reduced by almost 2 years from air pollution, driving up health care costs. In rapidly growing cities respiratory disease is on the rise causing many to wear facemasks as smog grows severe.

All change is not growth

Moving Backwards

Cities and Smart Growth

The article, published by http://www.epa.gov titled, “Smart Growth and Climate Change,” outlines the following smart growth policies for managing city growth:

1. Reuse existing infrastructure and buildings to take advantage of previous investments and energy already used to build them.
2. Put homes, jobs, stores, parks, schools and public transportation near each other. This could reduce Co2 emissions by 7-10%.
3. Preserve green space and promote development in previously developed areas.
4. Discourage building in areas that are currently or projected to be vulnerable to climate change related disasters, such as fires, storms, flooding, ect.
5. Preserve areas that will mitigate the disasters of climate change, such as coastal areas which can absorb the water from floods and hurricanes.
6. Encourage water and energy efficient buildings and land use patterns which can better prepare communities for drought and disasters.
7. Use green infrastructure to reduce the amount of runoff from paved surfaces.
8. Encourage green roofs, parks and planting of trees and shrubbery.
9. Design buildings for passive survivability that will remain habitable even if they lose external power for extended periods, and save on energy bills as well during normal operations.

Researchers also have found that roadsides plantings of hedges and shrubs were effective at reducing pollution exposure, cutting black carbon by up to 63 percent.

China's Giant Air Purifer

China;s Air Purifier fights smog.

China’s Skyscraper Air Purifier

Another recent invention to fight air pollution is taking place in China. NBCnews.com published an article in 2018, “This Skyscraper-sized Air Purifier is the World’s Tallest”, stating, “It may look like just another giant smokestack, but a 200-foot tower in the central Chinese city of Xi’an was built to pull deadly pollutants from the air rather than add more. And preliminary research shows the tower — which some are calling the world’s largest air purifier — has cut air pollution significantly across a broad swath of the surrounding area. Built in 2016, the $2 million Xi’an tower, dubbed the solar-assisted large-scale cleaning system, stands atop an enormous glass-roofed greenhouse. Sunlight heats the air within the greenhouse, causing it to rise through the tower, where a series of air filters trap soot and other noxious particles. Xu, who wasn’t involved in the tower project, added that it’s important to take into account the energy costs involved with building and operating the towers. If the structure requires electricity from the grid that is fueled by coal, then operating the purifying system will itself generate harmful emissions. “That will be not so clever,” Xu said.

Dr. Robert Harley, Professor of environmental engineering at University of California says, “Real progress in solving outdoor air pollution problems will require reductions in emissions from the major air pollution sources, such as heavy industry, coal-burning power plants, motor vehicles, and residential cooking and heating, especially if people are still using solid fuels such as wood or coal for those purposes.”

Innovative thinking must solve our current and future climate and pollution problems as cities grow, replacing rural life, and individuals must do their part in leaving a planet that future generations can comfortably occupy!

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 has been at the Root of Major Famines

Drought in India

Indian drought causes famine.

“The demand and supply of food has been in a delicate balance for the human species throughout history.”

By Dr. John J. Hidore

October 30, 2018—–The term famine produces an image of starvation and suffering in the minds of most people. In general a famine is a lack of food sufficient to produce malnutrition in large numbers of people over a wide area. The United Nations considers several conditions for a regional food shortage to be considered a famine. They are:

1. At least 20% of families in the area face extreme food shortages that they cannot cope with.
2. Acute malnutrition in children exceeds 20%.
3. The death rate exceeds two persons for each 10,000 people per day.

The Role of Climate Change in Historic Famines

There are many causes of famine, including climate changes, war, and political policies. One of the major ones is drought. Most of the catastrophic famines in historic times have been precipitated by drought. Drought can affect the quality and quantity of crop yields and the food supply for domestic animals. In the case of severe drought there may be a substantial loss of domestic animals due to lack of food. The loss of milk products or meat itself can precipitate the effects of the drought.

The demand and supply of food has been in a delicate balance for the human species throughout history. When the food supply has increased there has been a gain in population, and when food has been in short supply there has been some sort of trauma inflicted on the populace. Starvation results from insufficient food intake. During the long period of the hunting and gathering societies, starvation was probably often near at hand for individuals, family groups and tribes.

Indian drought

Millions effected by the drought

Agriculture and Famine

The development of agriculture allowed the world population to expand rapidly and greatly. At the same time, the basis for the supply of food, namely agriculture, became more directly dependent upon the weather. Famine as a phenomenon did not become a part of human experience until after agriculture began. However, as agriculture expanded so did the frequency of famines. The number of times that famine has spread on the continents is enormous. Nearly all histories of peoples and nations record famines.

Great famines have occurred throughout the Asian continent. India, China, Russia and the countries of the Middle East have all suffered from famine, many times which were drought related. An example is the famine described as occurring during the time of Abraham (about 2247 B.C). Another 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 to 400 B.C. and in China to 108 B.C. Since the time of the earliest known famine there have been nearly continuous episodes of drought and famine in many parts of Asia or Africa.

Indian drought

Global warming raises temperatures around the world.

The Impact of Drought in Developing Countries

Drought has a much greater impact on people in developing countries than it does in industrial societies. The primary reason for this is that in the developing countries there is more dependence on agriculture as a way of life. When crops fail, or there isn’t enough forage for livestock, there is an immediate effect on the populace.

A very positive aspect of famine is that they are becoming fewer and less extensive due to the ability of the global economy to move large quantities of food from place to place.

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.

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.

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 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!
