 Clean water is one of our most important resources. Our very survival depends on it. But where does it come from? If you look upstream, you will probably find a forest. Forests are vital to our water supply. They not only influence how and where rain falls, they filter and clean our water far better and more cheaply than man-made solutions can. So protecting our forests protects our clean water. Remember, when you turn on a tap, you're tapping into forests. Look after forests, because every drop counts.
