If you're referring to stemming climate change, you won't succeed. I doubt anyone will. Modern society depends on manufacturing, food, and travel, and nobody will give it up. It's a steep fitness landscape and doesn't really work because someone "breaking the rules" will have a substantially easier time.

Climate change prevention is a meme for rich countries. It's an unwinnable battle.

I'm not saying we shouldn't be paying attention. We absolutely should. But humans follow gradient ascent and won't be willing to handicap every area of life to make modest gains on the climate front.

Paper straws don't even make a dent.

It's happening, and we'll just have to adapt. Sucks immeasurably for the current biodiversity, but life has adapted to much warmer climate in the past. We should catalog what we can while we can.

To address your comment, I think you'll find greater success in extending the lives of rich and powerful people. Once they realize there's a long term ahead, they'll adjust their thinking and time horizons.
