First things first, yes, everything is connected. I had to get a few years under my belt or at least needed a chance to see life from a few different angles before I got that. The kids I know who are coming up now have a better grasp on the spirituality of that than I did. I'm guessing the intellectual aspect won't be too far behind.
I like Jensen, but IMO that's horse hockey. My guess is that we will either burn/gas/wash ourselves out in large degree because the rest of the world will try to emulate our consumptive western lifestyle -OR- our emerging technology will blossom just enough and will coincide with a giant "oh $#!+" moment and those of us who survived environmental catastrophe will carry on a little wiser and a lot more humble. It would be lovely if that happened before the big slap was necessary, but we don't seem to be on that course yet.
