There are many kinds of pollution, some of the major ones being air pollution, water pollution and soil pollution.
Pollution in all of these forms results in adverse changes in the environment.

Often, the changes induced by pollution irreversibly damage the environment.
Mainly, the main elements such as air, water, and soil become toxic in these instances and hazardous.
This eventually leads to a series of diseases in humans such as asthma, heart disease, and even cancer.

Inevitably, such pollution also affects other life forms such as plants and animals.
The effects of pollution are thus that they are harmful to both us and our environment.
We must thus strive to avoid pollution.
