paragraph writing on effects of water pollution

For example, pesticides and other chemicals have been found in the Antarctic ice sheet. Although urban areas are usually more polluted than the countryside, pollution can spread to remote places where no people live. When these resources are polluted, all forms of life are threatened. All living things-from one-celled microbes to blue whales-depend on Earth’s supply of air and water.

Pesticides-chemical poisons used to kill weeds and insects- seep into waterways and harm wildlife. Industries and homes generate garbage and sewage that can pollute the land and water. Burning coal to create electricity pollutes the air. Cars spew pollutants from their exhaust pipes. Many things that are useful to people produce pollution. Pollutants damage the quality of air, water, and land.

They can also be created by human activity, such as trash or runoff produced by factories.

Pollutants can be natural, such as volcanic ash. These harmful materials are called pollutants.

Pollution is the introduction of harmful materials into the environment.
