We have set up a section on our church web site, for the resources we are generating with regards to Christianity and the Environment, the site is here. In particular there is a series of talks/teaching on environmental stewardship that include:
1. There's No Such Thing as Christian Ethics 2. Slaves of Jesus - Consumer/Christian Identity 3. Redemption and Stewardship 4. Why God Values Creation 5. Seeing the Wood From the Trees
Also if your looking for an easy to read book as an introduction do try the book pictured above, 'Saving God's Green Earth'.
