The longer we delay addressing environmental problems, the more difficult it will be to resolve them.

We can't say we weren't warned. In 1992, a majority of living Nobel prize-winners and more than 1,700 leading scientists worldwide signed a remarkable document called "World Scientists' Warning to Humanity."
