Where can I find general information about what causes pollution?

LEVEL: Intermediate / Secondary

You may want to start with a simple site like Wikipedia. This page lists the common causes of pollution around the world. Many of them have hyperlinks to further information.

Hot tip: some teachers don't like Wikipedia, but we find it good as a starting point. Just make sure you find a few more resources that back up the information on Wikipedia.
