humans are such a silly, silly species, and utterly predictable in their inability to plan long term, which isn't exactly a mammalian trait, when you stop and think about it. Mammals are good about planning for something fairly short term (maybe a year, tops, but really those examples are mostly the response of the organism to seasonal fluctuations). But ask us to think long term, about our own impacts on our environment, and we come back to our animal way of thinking - almost without helping it. We attempt to isolate aspects of science out of the context of a broader understanding (it's getting colder for two years in row, so we know there's no climate change), which is the opposite of not planning for a year, and is Bernard Shaws' chicken, or we return to comments such as "it's just a conspiracy to raise taxes", a desire to be better off than "the other", who is our competitor for limited resources, and we do all this without really looking around, from a broad context, and seeing which way the wind is really blowing.
