Hi Lal Naja,
I agree re population. It seems that climate change may do the culling you speak of.
Some of the dangers they spoke of in the 70's were quite real I understand. I am not an expert on the topic but didnt acid rain kill the great lakes in Canada. Isnt that why they introduced lead free petrol. We also banned CFC's and that seems to have done the job. I dont think anybody offshore uses CFC's to my knowledge. These things can be done if governments refuse to purchase products from countries that do not comply.
I agree about follow the money trail but cant agree where it leads. The BRW richest list a whole bunch of minning executives but I have not seen any Greens. See link
