Overpopulation and the Environment

2021 Words5 Pages

Humans have greatly impacted the global environment. Throughout the course of history, human populations have rapidly increased. Especially in Africa, these numbers have reached extraordinary proportions. Out of all the continents in the world, Africa’s population is increasing the most. The type of growth here is exponential. “Overpopulation is a condition when an organisms numbers exceeds the carrying of its ecological niche.” The growth rate of a population is equal to the birth rate minus the death rate. Therefore, for overpopulation to occur, the birth rate must surpass the death rate (Wiley). The current population of Nigeria is estimated to be 155,215,573. Most of the population consists of the younger generation. More specifically, 41% of the population is between the ages of 0-14. 56% of the population is between the ages of 15-64. However, only 3.1% of the population is 65 and over. This age group represents a very small part of the population. (CIA)

Overpopulation drastically affects the standard of living of the people. Not only does it affect the standard of living, it affects the environment as well. The environment has a certain carrying capacity of humans that it can support. When this carrying capacity is exceeded, the environment starts to deteriorate. With a large amount of people, land that can be used as valuable farmland is wasted. Also, with a great amount of humans, there is more waste produced. This waste contaminates local water and spreads disease, eventually leading to the destruction of wildlife. Animals as well as humans have a limited use of water because of the microorganisms and fecal matter in the water. Many ideas have been debated upon to help improve these conditions for both animals and peopl...
