What is air pollution?

 Pollution is any material introduced into the air that can cause negative effects for the environment and human health. Pollutants can come from natural sources such as wildfires, but most air pollution comes from human activities such as energy production. These activities can emit greenhouse gases, leading to warming temperatures and climate change.

Why does it matter?

Poor air quality is bad for our health and the environment. When we breathe in dirty air, we breathe in small particles of pollution that can get into our lungs and bloodstream, causing health problems for everyone, especially those in high-risk groups. 

What can I do?

The best way to prevent air pollution is to drive less. Gas-powered transportation is one of the biggest sources of air pollution and greenhouse gas emissions. To reduce these pollutants you can walk, bike, take public transportation, drive an electric car, or carpool to your destination.
