Earth is home to millions of species. Among the millions of species, there is a superior species called humans. We are humans! And it is kind of ironic that we are known as superior species since humans are solely responsible for harming and polluting the environment.
It is not novel to us that overpopulation does have a negative impact on the environment. The harmful effect of the human population over time is not limited to harming the environment in a single or only one way.
There are multiple ways through which overpopulation affects the environment. Some of them are discussed below-
- Farming impacts
We all know that humans need food in order to survive and for getting food humans are dependent on farming for a very long time. With the advancement of time and with the increasing population, demand for food has risen.
There were more mouths to feed than there was food and to overcome this difficulty, farmers with the support of the government started cutting the forest in order to increase their hold on land that was fit for farming. As a result of this practice, forests started to shrink at a great pace thereby damaging the environment and natural habitat of animals at the same time.
Due to population rising at leaps and bounds, it was becoming impossible for the superior species to build houses to live in, it was becoming hard for superior species to pass through the forest in order to travel from one place to another. So they arrived at the conclusion of cutting down the forest altogether to build houses, roads and to increase farming capacity.
Eutrophication is the process that happens in a water body like a lake or any river. When too many nutrients are added to the system of a lake or the river through fertilizers or any other human activity, it is called eutrophication. The nutrients are the food for algae which results in the exponential growth of algae. The algae present on the surface of the water makes it impossible for the plants beneath the algae to photosynthesize, and that ultimately results in a loss of oxygen in the water. As a result of this, the ecosystem of the water body becomes disrupted thereby leading to loss of life in the water body.
Population spurt has forced village people to move to the cities to make their ends meet. Sometimes what happens is that due to unemployment people resort to unconventional ways to earn money. A large population is the reason behind unemployment and unemployment is the reason behind the elevation in the crime rate.
