Creation Care is the term Evangelicals are using regarding environmental issues.
Mark Connors has put up a few links to Creation Care, on his blog. Which are worth checking out::
For a good introduction to a biblical theology of Creation Care, click here for a free PDF of a chapter by Bret Stephenson and Stephen Bouma-Prediger from their book Living the Good Life on God's Earth.
Another very good book on this topic is: For the Beauty of the Earth: A Christian Vision for Creation Care. The Evangelical Environment Network also has an informative web site. Click here to access a website on Creation Care for pastors.
