Pollution

Pollution

It's bad for the environment (and people too!)

We get the oxygen we need by breathing air. It’s such a natural thing that we don’t usually stop to think about what’s in the air we breathe. But besides oxygen and other elements like nitrogen, air also contains pollutants, which can be harmful. Air pollution is a problem that affects life all over the world.

Many human activities create air pollution. In turn, the pollution causes problems for our health and other life on Earth. To help improve air quality, it’s important that we learn about what causes air pollution — and what we can do to protect life on our planet.
