I'm here for a short time. There's enough crap to find to worry about if you look. I'm not pouring chemicals into the stream nearby. When I go fishing, I usually pick up trash to make it better than when I found it. I don't burn stuff that might create toxic fumes.
I'm not going to take on the world's farking stress over something that I, personally, can't do much about. Enjoy life.
Conservative mantra: I'm going to be happy. fug everyone else.
