In light of another discussion, I wanted to understand to what extent people try to be more environmentally friendly in their personal lives. Instead of people listing the ways they try to be more environmental (too easy), are there areas where you believe your activities are particularly harmful of the environment that you wish to correct? What stands in your way?
I try and reduce consumption as much as possible and have a number of quirks regarding dutiful recycling that my peers find hardcore. But I struggle with air travel. My job requires me to undergo occasional air travel. I try and do trains and even busses whenever possible, but some destinations are simply not accessible without air travel (EG spreading capitalism among the filthy socialist masses in Berlin). More generally, I struggle to get co-workers to do things like take a 1.5-hour train ride when they'd prefer to rent a car for the day.
How do you bring up these issues without making people uncomfortable?
