The driveway problem isn't a major problem in my life. It's practically already solved. I cannot go around turning every minor problem into a mountain of effort, and it'd be stupid to think that everybody doing this is going to fix the environment. I won't do it. And nobody else will either.

If they were going to do it, it would already be done. The reason we haven't done it yet is the same reason we won't ever do it. Individual responsibility is not a solution here, so I'd rather we not bet the future of humanity on it being one.
