Looks to me like he's a man from England (Yorkshire?) who is not happy with what's happening to the environment. It looks like he feels (with some justification, in my opinion) that American consumerism is at least part of the problem. And it's pretty clear that he has no love for GW Bush. He also enjoys a pint or two of an evening, and taking the piss out of the rest of us.

Am I close, SF?
