I think that attitude is becoming more common. Maybe it's just my bubble of the kind of friends I retain, but in general, at least everyone is aware of it and in my bubble most people actively consider at least some of what they do.

The biggest problem I find is people saying "we can't do anything anyway" or "it's never enough". I dunno man, if you actually thought you could make a difference, maybe we all together could? Look for green energy providers that actually invest in building new renewable energy plants, buy more second-hand items, don't fly short-haul when you can take a train or tell your boss that you want to at least offset such emissions, and break the pattern of going everywhere by car (if possible, I understand transit is difficult in the USA). And of course, vote the right way.

All of that shifts where your money goes and very few of these things would actually impact your daily life, perhaps the only major one being your commute if it is realistic for you to use the bus/train instead of a car. It might get a little longer, you'll have to accept that you get near other humans that you haven't hand-picked, but if coexisting is too much to ask...

We can do it, if only we accept the idea that we can tackle something bigger than any individual or even an individual industry.
