A World Health Organization report found that the fossil fuel economy and industrial civilization is already leading to 1 out of 8 deaths among humans each year (the number would be high for non-humans too). That is an immediate danger, more immediate than what climate change may be contributing to now. In the developing world, the main culprit is burring biomass for cooking and heating, with women being at greater risk than men. In the developed world, the main culprit are fossil fuel automobiles and industrial production.
