I agree with the last part. There is a huge amount of moral licensing as well (I recycled this cardboard box, so flying to Aruba is ok). But I think both collectively and individually we are unwilling to make the required sacrifices. You're right, the actions of one person don't make a significant change, but they do make some change. If everyone who said they were deeply concerned about the environment started to make the changes that are required, we'd start to make a dent. And perhaps have a larger effect than themselves. But they won't. We're all mostly just hoping that massive change doesn't happen until after we die.
