If only we could get that idea in people’s heads.

Seems misguided to me. People only do these sort of society-wide prosocial actions when it is within their convenience tolerance. It reminds me of this:

Sure, you occasionally will run into the desperately poor person working 3 jobs who also finds the time to pick up litter in their local park. But most of the time this person has more important things to think about than litter - like getting a job that doesnt require them to work 3. The idea that we need to get people to be more pro-social so they will take the bus feels a lot like the idea that we need to teach people that exercise is healthy so they will cycle more. But the reason people don't cycle, we know, is because it is inefficient and dangerous, and the reason people don't take transit is because it is slow and unpleasant. And when cycling or taking transit is faster, cheaper, safer, and more pleasant than driving, people do that.
