Pollution tests in Nigeria

Pollution is when harmful substances are added to the environment and then change it in a bad way. There are six kinds of pollution of the environment: water pollution, air pollution, light pollution, noise pollution, soil pollution and thermal pollution.

As pollution grows, ways to combat it have been in demand. Solar energy and wind energy give people clean opportunities to power their homes. But these may also have environmental issues depending on the situation. When people use these alternative forms of energy, they put less carbon dioxide into the environment.
