The Bible has always talked about taking care of the Earth. As a matter of fact, that's the first order we got in the Garden, where it said to cultivate the earth and keep it. The Hebrew words are abad and shamar – you see them on police cars, they mean "to serve" and "to protect." And throughout the Scripture it talks about taking care of the gift of creation, and so on. However, the problem is that it's not been very high on our priority list. Most of evangelical Christianity has not really paid attention to that until recently, when this climate-change revelation brought it to our attention. This is a front-burner issue now, because we are fast polluting the earth to the extent that the poor especially are going to be hurt. Knowing how Jesus always prioritized the poor and cared for those who are vulnerable, we've always known we're supposed to do this but we've never really done it.
