One of the best known Christian bloggers is Canadian Tim Challies, his blog is well worth reading even if only to see what makes a great blog. Tim devours books in a way that I devour my wife’s chocolate biscuits. Anyway he’s been reading recently on the issues relating to the environment.
His book reviews are always thoughtful, insightful and usually helpful, I recommend checking out his blog and reading the following reviews:

• Francis Schaeffer’s Pollution and the Death of Man
• Matthew Sleeth’s Serve God, Save the Planet
• Al Gore’s An Inconvenient Truth
