Demanding multiple extreme lifestyle changes from billions of people—most of whom don't like you and won't listen—seems like would make for the least effective and most damaging of all the available solutions.

I prefer solutions that involve changing the least number of stubborn and uneducated minds, and offer the most upside. Like industries that are run by professionals and are already accustomed to high regulatory requirements. Energy and construction industries seem like there's a lot of low-hanging fruit there, just for starters.
