Q. Dear Umbra,

Let’s say I win the lottery, and want to use my $50 million winnings to save the planet. For example, I could fund enviro groups. I could fund political campaigns to defeat Big Oil’s congressmen. Or I could provide subsidies to buyers of electric cars. But where would I find the biggest bang for my big bucks?

Hypothetically yours,

A. Dearest Mark,

I would suggest you donate it to Grist. As it happens, we’re in the middle of a fundraising campaign, and $50 million would go a long way. (So would $5, come to think of it.) Imagine all the cruelty-free peppermint tea I could buy with that kind of cashola!
