I think the ones doing the blaming are the ones most at fault, like the Sierra Club, the Nature Conservancy, Greenpeace, World wildlife fund, Audubon society, National wildlife federation, and other environmental groups. these groups pretend to be saving the environment, but in fact are enablers of irresponsibility on a grand scale. I think they know they are to blame for letting forests build up huge amounts of fuel, but like every thing else with these type of people, the blame must be placed on someone else.
Many of these environmental groups survive on the idea that they are saving nature, the earth, and the environment, and they receive large amounts of money in the form of donations from people that don't know any better, and have bought into the idea that these groups are saving us from ourselves.
