Introduction to Pollution
Pollution happens when we put dirty or poisonous things into our surroundings like the air or water.
Pollution is the release of toxic or harmful substances into the environment.
This means that when harmful things enter our world, we call it pollution.
This can happen because of things that happen in nature, or because of what people and animals do.
When pollution happens, it can cause biological damage, which means it can hurt or kill living things.
In simpler terms, pollution involves putting harmful substances into the environment.
These bad things are released in large amounts that can be dangerous to humans, crops, and animals.

We call the dirty things that cause this trouble pollutants.
Pollutants are the contaminants that lead to pollution.
So, any substance that makes the environment dirty is a pollutant.
Pollution can come from things in nature, like dust or smoke from bush fires, and also from things people build like factories and cars.
The three main types of pollution are:
Air pollution
Water pollution
Land or soil pollution
