I'm not at all sure of this, just caught my attention looking over this page quickly . I think it is likely that other posins in the air, food and water supply are thousands of times more a problem than co2 is. This would take at least 5 minutes on the internet to confirm though. (haha) Just remembering recently: (this is only one of several about 12,000 dying daily) > "The report also named ambient air pollution responsible for 40% of all pollution-related deaths, led by China, India and Pakistan (1.2 million, 1.2 million and 130,000 respectively). The number of global deaths linked to pollution just exceeded those from tobacco use, which stands at about 8 million, but greatly eclipsed deaths from alcohol and drugs, high-sodium diets, HIV, malaria, TB, and war, it said."
