Yes that's true, the conditioning you talk of. What I meant by "we" was the masses - in the way of vehicle exhaust, CFC's, Air Pollution, etc.
I didn't mean "we" as if we had done it intentionally either - and I'm sure however "it" happened, whatever "it" is, no one did it intentionally.
Really, who would just wake up one day and say "gee, I think I'll destroy the earth today, I think I'll just go make it unfit for humans to live on"
No one, of course. But, if I may quote a phrase from a religion that I don't believe in, The road to hell is paved with good intentions.
But of course, being the political chickenshits so many of "them" are, they try to rectify the mistakes that have been made silently, usually just mucking things up worse in the process.
I don't know what the purpose/reason for chemtrails are...
I certainly don't have any answers and all I'm doing now is offering conjecture...
But, reasonably, throughout history - aside from a few very sick individuals (holocaust comes to mind) - most people are interested in the greater good I think.
Some poor unsuspecting scientist probably said, "hey! I know how we can control global warming... we'll have less sunny days though" and he was trying to be helpful.
Maybe it just helps me to think like that so that I don't have to live in fear - that is the reason I'm not religious. I refuse to live in fear, and if I go around thinking there are huge government conspiracies going on then I'm afraid for myself and my family.
