One of the major issues facing people who care about the earth is sustainability: how do we live on the earth and sustain ourselves without taxing natural resources or wiping them out entirely?

The Sustainability Institute is focused on just this issue and has a great website dedicated to exploring issues of sustainability and ways to improve how we live with the earth. You might check out some of their projects or make use of some of their resources or make a donation. Whatever you do, it’s a site worth bookmarking, if only for future reference/use.
