Overpopulation Results in Global Stress

Are there enough resources for overpopulation?

With climate change will there be enough resources for all?

Climate change can decrease the carrying capacity of a region.

By Dr. John Hidore

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

Overpopulation Defined

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

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

Carrying Capacity and overpopulation

What is Carrying Capacity?

Processes That Create an Unsustainable Population

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

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

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

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

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

Overpopulation: The Big Question

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

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

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

The evidence of overpopulation is severe!

Investors Support Population Growth for Profit

Overpopulation and wallstreet

Do Republicans support overpopulation?

“Should the Republican Party sweep the coming elections, the availability of family planning services will be greatly reduced and our population will continue to grow at an unhealthy rate.”

By Dr. John J. Hidore

September 22, 2016—-The human population of planet earth is under a great deal of stress. Civil uprisings and violence are widespread. There are a variety of factors responsible for the stress. They include population growth, resource depletion, climate change, and the rapid concentration of wealth in a small group of super rich.

Slowing Population Growth

There is no simple answer to these problems but slowing or halting population growth provides part of the answer. Much of today’s global unrest and violence can be traced directly to overpopulation. The population in large areas has simply grown to the point that there are no longer enough resources to provide even a basic standard of living. However, there are those that profit from the rapid growth and are working to prevent efforts to slow the rate of growth.

Population Growth and the Corporate World

The global population is growing—80 million people each year. It is now adding a billion every 12 years. It’s clear the earth cannot sustain this kind of growth. Wall Street and its investors want to see our population grow. The operating philosophy of the corporate world is economic growth. Economic growth has been the cornerstone of political and the economy since the advent of the industrial revolution more than 200 years ago.

Corporate Profits and an Expanding Market

The industrial revolution was about increasing the production of manufactured goods for profit. Corporate profits depend on expanding the market for their manufactured goods and services. This can be accomplished in either of two ways. The first was to expand the market geographically and the second was by reducing the price of the commodity. In the United States, 70% of the Gross Domestic Product (GDP) is now generated by services, and so the major market is the size of the population itself. Increasing the population automatically increases the market for goods and services. Based on this simple principal of growth, corporate America has opposed any effort to slow the population growth.

Planned Parenthood

Opposition to Defund Planned Parenthood

In the United States, there is a substantial effort to reduce family size through methods of birth control. However, there are more than three million unintended pregnancies each year. Most are not using oral contraceptives simply because they do not have access to them. Planned Parenthood of America (PPA) is one of the most prominent groups providing these services. The demand for their services is high. It is estimated that twenty percent of American women have been to a clinic operated by PPA for health reasons. Most of the clients are low income and have no other health care provider.

The Republican Party vs. Planned Parenthood

There is now a major movement in this country to eliminate birth control. The opposition to these services is led by a variety of groups which consider themselves as being pro-life. One anti-abortion group even produced a video supposedly showing a clinic selling fetal parts after an abortion. The video has since been shown to have been fabricated.

In recent years the the government has supported Wall Street’s position. The Republican Party has long prevented US funds from being used for family planning in foreign countries. It is now supporting the religious right in efforts to defund family planning in this country. They consider contraception to be a form of abortion. They thus argue that contraception is not compatible with the pro-life movement.

Opposition to the Affordable Care Act

The current congress is also in opposition to the Affordable Care Act under which contraception is available. As a result opposing contraception has become a Republican strategy. The house of representatives proposed the defund Planned Parenthood act of 2015 (HR3134) last year. This bill would prohibit any funds from being used for any purpose by Planned Parenthood Federation of America. The 114th congress blocked funding for Planned Parenthood for providing abortions. This bill would remove nearly half a billion dollars from the organization.

Also in 2015 congress setup several committees to investigate Planned Parenthood. Fortunately, President Obama has prevented these bills from becoming law. Many states have since passed their own laws limiting family planning. Should the Republican Party sweep the coming elections, the availability of family planning services will be greatly reduced and our population will continue to grow at an unhealthy rate.
