I don't have personal judgement towards you or anyone else here about the topic, like Peter, i just disagree with the extreme, overly passive view expressed. Again, i'm not talking as much about carbon footprint and global climate change, but more about long term pollution issues. I happen to think global climate change is probably two parts long term natural cycle to one part human influence. However, even if that is objectively true (i don't know if it is), again i am concerned about the pollution aspect.
It is frustrating to know, that as much as i try to do as an individual, that it doesn't compare to the effect that factories, and various other extreme pollution sources output, and little i can do about that since our society has come to view these as completely necessary.
If i seem on a high horse about this, it may be because i had some recent, somewhat frustrating experiences, which i did apply my big picture philosophy to, which helped when i started to get those twinges of anger, stress, and/or sadness.
I volunteered at the FireFly Festival recently, so for four days, for about 6 hours a day, i was picking up trash and recycling. What i saw and experienced was kind of upsetting in it's extremity. Seas of trash littered on the ground when there were containers with room right there, people throwing large amounts of recyclables into the trash containers and large amounts of trash into the recyclable containers. It seemed obvious that some people had no idea what the difference between the two was, or either didn't care. Occasionally people (mostly women!) thanked us for doing the work which was nice, but i really couldn't understand why so many people couldn't just responsibly and correctly put away this stuff.
Btw, i didn't volunteer for any noble purposes, volunteers got into the festival for 25 dollars vs 200 or whatever other folks were paying total (parking, camping, ticket). However, i didn't really want to go in general, but my wife convinced me despite my misgivings. I did really enjoy the Foo Fighters show, until it stopped, people left and the sea of trash on ground appeared...
So maybe to some extent, i'm proving your points, but i still believe that positive change can happen if enough people care enough.
Perhaps that's naive. I'm not too worried about it though, because for a long while (since about age 12), i've been getting a strong feeling that something big is going to happen to change things. I've been getting this feeling before i was even aware of or cared about any of this kind of stuff. I've come to trust these kinds of feelings, because they often prove accurate and helpful. Like, i've had experiences when i'm speeding (something i try not to do for various reasons), and have gotten a feeling to slow down or literally "cop" popped into my mind out of the blue, and sure enough a little while later, i see one. I've had other more dramatic experiences along these lines as well.
But, even though i do think some big change will happen in the near future that will totally reorient everyone and probably reduce population quite a bit, i still plan to do my part meanwhile, because i know it's important to live mostly in the present and do ones best now. And ultimately, while i think it's important to treat the Earth positively and with respect, i think it's even more important to treat people positively and with respect.
