What is Overpopulation?

Overpopulation, is simply a situation where too many people live in a location than space, economic and natural resources can sustain. This means it is not just a specific number, but a relationship between the inhabitants and the resources available.

Before we get into the subject of overpopulation, it is important to understand the term Population. Population is defined as the total individuals of a species in a given geographical area over a period of time. Population is a concept of numbers. Population is not only used for humans living in an area. It is a scientific term that can also be used in the study of all kinds of living species such as trees, birds, and even algae. For example, the human population of Ohio was 11.62 million in 2016, and the population of young bald eagles in Ohio was 327 in 2016.

The world population in 2016, according to PRB was 7.4 billion
It is important to note that it is not just the high number of people in that location, but importantly the ratio or connection between the number of people and the available sustainable resources in that location.

Some people believe that overpopulation is not a bad thing, because the earth has enough resources. Others believe that as populations expand, there will come a time that the resources on earth can simply not cater for all. Unfortunately, humans take out more from the earth than they give back in the form of recycling, reusing and reducing our dependence on new raw materials. We do not plant more trees than we cut and that thinking is certainly what will create problems down the line.

The effects of overpopulation on the earth (including land, water and the atmosphere and all of its ecosystems) can be felt both locally and globally. For example, polluted water bodies can carry its pollutants thousands of miles across the seas to other areas. Overpopulation, overconsumption, overuse, misuse, wastage of resources have reduced the earth's resource capacity.

Is your country overpopulated? Is your city or town overpopulated? What kind of problems does it bring? Are there any advantages to being overpopulated?
