Actually what your're sensing (at least in my case) is an awareness of reality. The reality that: 1) the planet is changing constantly, just as it has for about 5 billion years, now; 2) for most of those 5 billion years, you and I couldn't have survived in the conditions that existed then, anyway; and 3) there are billions of people running around, supposedly causing all the problems - and I'll admit that if they aren't causing them, they certainly ain't helping stop them, either- and they don't give a tinker's damn what you or I think about
anything. So, what do you want me to do about it? No one ever seems willing to answer that question, other than the usual "recycle, don't drive when you can walk, etc. etc." mantra.. because no one will admit that the only real answer is:
make about 5 billion people vanish overnight. We both know that won't happen, and who has the right to say it should? I certainly don't - do you? So, yes, it's right to be aware of the problem; and, yes, it's right to do what you can, personally, to minimize your own impact. But, running around like Chicken Little (and I'm not saying
you - or anybody here - is) is really not much of a help. It reminds me of a girl I knew in high school who worried constantly- and I mean
really worried- about the fact that, 5 billion years from now, Earth was going to be burned up when the sun became a red giant. Life is too short to mess it up by worrying about things you can't fix. This is one of them. Play your bass, minimize your carbon footprint, and be as happy as you can. That's what I'm going to do, in the little time I have left.. before the giant red sun burns us all up.
