Global Health Problems Indicate the Need to Limit Population

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.

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.

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!

My goal, as a responsible adult, is to leave a planet that people, plants, and animals can continue to occupy comfortably. I am an educator by profession. While educating myself on Climate Change and Renewable Resources, I hope to share my knowledge and images with those that share my concern. Dr. John J. Hidore is a retired professor from the University of North Carolina at Greensboro and I am proud to call him my Uncle. His work has taken him to regions across the globe—including the Middle East, where he conducted research for a year in the Sudan. He has written many books, such as Climatology: An Atmospheric Science and Global Environmental Change.----Linn Smith
