Dan Ariely wants to know why we have paid more attention to the BP spill than other environmental disasters:

Here are a few characteristics that might differentiate the BP oil spill from the destruction of the Amazon. First, it is a singular event with a precise beginning. Second, while the tragedy was ongoing (and we are not yet sure if it has ended or not) it seemed to become more desperate by the day. Third, we have a single organization that we can villainize. In contrast, in the Amazon, there are many organizations and individuals at fault, both in the countries where deforestation is occurring and abroad. And fourth, the Gulf is so much closer to home (at least for Americans).
