> My recommendation: Make as much money as possible, and lobby for cap-and-trade pollution credits. Then you can buy all the credits you want, and simply not use them. It is a far more direct and economically predictable way to achieve environmental change.

I very much agree with this solution. I'd also consider the funding of genetic research into bacteria that could convert oil in situ into something stable in the ground so it could never be pumped into the future, pumping said bacteria into wells using the same equipment used for hydraulic fracturing.

We as a species have a terrible track record as stewards of our planet. We can, and should, do better.
