"We need to take action - smaller families, reduced travel, less meat consumed, fewer power- guzzling computers."
Just so you're clear, making your life suck in these ways not only will leave you sadder than necessary, but also make no difference in climate change. Ask any reputable climate scientist and they'll tell you the same thing: personal choices, even in aggregate, just don't do enough damage to matter. The real problem is mostly industrial/commercial but those guys have lobbyists so instead you don't get plastic straws anymore (responsible for a vanishingly small portion of the plastic in the oceans, btw, unlike illegally discarded commercial fishing gear which is responsible for about /half/).
The only thing you're doing by eating nuts and driving a Prius is flexing on your neighbours. You haven't made a difference. Sorry. If you want to make a difference lobby your local legislators to go after the actual problems.
