Any solution that requires individuals to “just” do something that’s contrary to their nature is not a solution.

No society has ever solved a serious problem by “just” doing something on an individual scale en masse.

Think about what you’re suggesting. Individual action that acts like coordinated action. It’s impossible at scale. It’s a total contradiction.

(This is not even touching on the fact that the vast majority of oil use and pollution comes from military, energy, and industrial uses, not individual consumers.)

This does not imply that every problem can or even should be solved, but you’re not going to solve it this way.
