You shouldn't really feel guilty about anything like that. Asking hundreds of millions to billions of people to drastically change their lives and practice austerity is insane while billionaires do whatever they want and corporations push legislation that makes it harder to conserve. Our meager efforts won't matter much if the biggest offenders go pollute wantonly.
Individual's biggest efforts are pushing for legislation and politicians who will curb corporate abuses. Everything is a drop in a bucket that's already overflowing.
