Habitats destroyed. Countless animals dead or wounded. Millions of people left without clean water or fresh air. All of these things are caused by our pollution of the environment.
Pollution is a major issue that if left alone could destroy all life on the planet. Many places in the world are already starting to feel the effects: in many coastal cities, water levels continue to rise, and in places like Beijing, China, people often have to wear gas masks to go outside.

What you can do

We need to help stop pollution. You can help to do this by recycling, picking up litter, conserving energy, or doing other things that are generally considered Eco-friendly. Alternatively, you can contribute to an organization that fights pollution, such as the World Wildlife Fund (http://www.worldwildlife.org/threats/pollution) or the Sierra Club (http://www.sierraclub.org/#sierra-2-modal-1).
