Water pollution mainly occurs because factories release their dirty water into rivers and oceans. This water can contain chemicals that hugely affect the animals living in it.

Another cause of water pollution is people throwing trash into the water. Things like plastic bags and bottles do not disappear easily and can pollute the water for a long time. This can harm fish and plants.

Last but not least, vehicles can also cause water pollution in an indirect way. For example, when cars and trucks burn fuel, they release gases into the air. When it rains, these gases can mix with the water and fall into lakes and rivers. This causes more pollution.
