There aren't always bigger things. There's always one at the top. That's where changes can have the biggest impact. And where peoples focus needs to be. "_What's **your** carbon footprint?_" was a marketing slogan from the big oil companies to steer the environmental movement away from them (where substantive change was possible) onto everyone else, so they could dodge responsibility. It worked remarkably well. You still thinking that way is testimony to the fact.
