Given the fact that we share a planet: Wouldn't it be desirable to convince people to make buying choices that ensure our collective survival in the long term?

Given the fact that we share a planet: Wouldn't it be desirable to convince people to make buying choices that ensure our collective survival in the long term? If you agree with that thought: Wouldn't one way to do this be to pool a small part of our collective money together and give it to people who are then swayed (or enabled) to use it for a more sustainable infrastructure? IMO this is a no-brainer and given the collective costs of the weather extremes accompanying the ongoing climate catastrophe it might be even financially viable.
