John Smulo makes an excellent comment on Christian attitudes toward creation in his post Spoiled Brats
This seems to be one of those "pond differences".
I could be wrong, but I have the impression that most most UK-based Christians would be in agreement with John no matter whether they call themselves "conservative", "Middle-of-the-Road", "liberal" or "please don't label me, I'm just a Christian".
For some bizarre reason that I can't understand, many American Christians seem to think that human beings don't have any responsibility for the environment and that claiming that we do is some sort of declaration against God's sovereignty. I certainly hope this view is changing!
I recommend to you John's article.
