And one way to "push for that regulation" is giving an example that you are not hurting yourself too much if your choices reflect the legislation you demand.

If you ARE in fact hurting yourself too much, then you prove that people can chose one from the following:

A) keep the status quo, but the planet will most probably heat up and very bad things happen.

B) change the status quo to something that really, really hurts. But the reward for your surrender is that there is a chance that the planet does not heat up so much and less bad things happen a few decades from now.

That is what most people perceive in climate activists.
