pollution is contamination by a chemical or other agent that renders part of the environment unfit for intended or desired use. It deserves emphasis that the environment also refers to the place where you live. Natural processes have released toxic chemicals into the environment throughout the history of the earth. Currently, the pollution generated by human activities presents the most serious problem.
There are basically 3 types of pollution. They are:
1)air pollution

2) water pollution
3) land pollution
some of the major causes of the pollution crisis are as follows:
I) deforestation – for the establishment of factories, industries and due to urbanization in various parts of the world, trees are cut on a large scale without any adequate efforts to plant new trees. This leads to deforestation, which has caused a rise in the pollution levels and distortion of natural order.
Ii) polluted rivers – the wastewater and liquids from plants and factories are linked with nearby river water, which are polluted when they release disposal from these units. People in developing/undeveloped countries also pollute rivers by using the water in these rivers for washing clothes, utensils, bathing and other activities.
