Bob, I find your comments very interesting and also helpful.
Thank you for pointing out these issues. I recall years ago thinking that people shouldn't be jogging/training in cities because of the bad air. I've long wondered about tires. There is a park with a playground whose surface was covered with chopped tire bits. It makes for a springy surface to run or fall on but it's quite unpleasant to smell and breathe. I went there once and never went back. I'm not particularly sensitive but I felt crappy after that afternoon. The parents' attitude was, 'You get used to it' and 'It's supposed to be safe'.
Similarly, you pointed out the wells being filled with waste water and the danger they pose contrasted to the attention fracking gets. Thanks again.
I'm also interested in the idea that the climate changes are eliciting extreme measures. I don't understand why the government/private institutions don't practice more openness. 'Two heads are better than one.' 'The whole is greater than the sum of its parts.' Doesn't it make sense to have everyone involved in finding solutions?
