In today's global marketplace of ideas, the idea of "saving the planet" or "going green" are really two similar ideas that find their origins in the environmental movement, a movement based in part on animism - the belief system that not only do humans and animals have souls, but so do all things in nature including rocks, plants, trees, etc. By now you probably realize that I have a bias against environmentalism, "going green", and animistic practices, and you are right because I am a Christian, which is to say that I am a follower of Jesus Christ, the Bible (which was written by men throughout antiquity to teach us about who God is, and his plan of salvation for each individual through Jesus Christ), and the teachings of orthodox Christianity which comport with the teachings contained in the Bible.

There is a good article today from theResurgence.com about a recent Time magazine article: 10 Ideas Changing the World Right Now: 3. The New Calvinism.

It's an interesting summary from a secular source about what many Christians have already noticed about Christianity - the format and focus is shifting, but not away from the Bible, just away from the 1980's - 1990's excessive legalism (usually labeled "fundamentalism") and towards a more balanced understanding and application of Biblical principles and truths. It's also interesting how the article starts off dripping with sarcasm about what Christianity is, but has a harder time being so down on it when the author is just giving the facts from other sources half-way through.
