Ending today's crisis is as easy as naming tomorrow's scarier one Last weekend I caught several hours of the consciousness-raising Live Earth concerts. I'm already on board regarding the scientific consensus on global warming, but like many, I'm uncertain about how much priority humanity should give this crisis versus others we collectively face. Humans crave life-focusing crises. As globalization generates inescapable complexity, it's nice to have one big boulder to push up that hill every day, no matter how Sisyphean the task. We're naturally resilient creatures, and self-sacrifice is embedded in our evolutionary code.
