I would imagine that his individual footprint is pretty small compared to the rest of the world.
I never understand why we would ever focus on a messenger and not the message. The entire planet needs to be focused on creating renewable energy sources to meet the demands of what will be nine billion people pretty soon. If there weren't people who thought global warming was fake and oil was renewable, there wouldn't be a need for celebrity politicizing.
are these the same messengers who champion how they saved the US auto industry?
