How does deforestation affect the Earth?

Level: Intermediate / Secondary

A simple Google search on deforestation does bring up some great information. But if you ever want to know how one thing affects another, try adding the word effects into your search e.g. deforestation + effects. Other useful add-on words for these types of searches are causes or impacts.

HOT TIP: Google is pretty good at doing natural language searches too - so most of the time typing in your original question will produce good results. Sometimes you may have to ask the question in a slightly different way, for example what are the impacts of deforestation?
