Why is it that no one is excited? I hear people talking in the laundromat about the end of the world, and they're no more excited than if they were comparing detergents. People talk about the destruction of the ozone layer and the death of all life. They talk about the devastation of the rainforests, about deadly pollution that will be with us for thousands and millions of years, about the disappearance of dozens of species of life every day, about the end of speciation itself. And they seem perfectly calm.
