when I look at everyone around me not really giving a shit. ... I really worked hard to reduce my footprint
For years I did this. Didn't drive. Rarely flew. Mostly vegetarian. Bought mostly second hand stuff. It was a lot of work. It had no appreciable effect on climate change, and made my life harder.
I think the place to concentrate effort is on policy change. Acid rain wasn't solved (in North America) by buying patterns, it was solved through legislation. CFCs were phased out through lobbying.
There's definitely a time and place for personal action, but there are so many people that appreciable changes will only come through changing regulations.
