Okay, but just what is 'pollution'?
Can animals pollute? You know, like a whale going potty in the ocean or a duck relieving himself as he flies over the trees?
Can nature pollute? Or is pollution only something mankind can do?
If so has mankind always been a polluter? Or only since the Industrial Revolution?
Do non-Cauasian pollute? You know, like primitive tribes in Burko Faso, or the Amazon-- do they pollute?
And if pollution is (chiefly) man made then how can there ever be an end to it?
Who decides what is 'pollution'? Who decides who decides?
Are you serious? There is a huge difference between doing an imperical study on the affects of levels of arsenic in drinking water over a period of time to determine what the standard ought to be and what Clinton did, which was to arbitrarily lower the reporting limit on Arsenic in his waning days to placate his nut-job base who are scared of the word "arsenic".
The hard part at this point is to re-instate the Scientific Method and get rid of the preconceived dotions of the baby boomer "scientists".
