Isn't God already green?

This made me swing round and jump out of a car to photograph this absurdity.

How does a church recover from a statement like this? Isn't this challenging the actual EXISTENCE of God? For if God really is all knowing, omnipotent and all seeing, is god not already green? If God is going green, what on earth has God been doing before- littering? Good grief. I'm trying to get Michael to come with me to the sermon so we can find out.
