Being apathetic at home isn't going to inspire others to do better. And there is no one silver bullet. The mess was made by many bad choices. It will take many better choices and laws to turn things around.
This isn't apathy. It's real talk. If you don't like it, I don't know what to tell you. I explicitly said we should do this in another comment. My problem is with calling it a "fix."
My best suggestion is that if you invent a time machine, go back to about 1950 and see if you can nudge events in such a way that the climate crisis doesn't happen.
