Pretty lucky our unique specialization, the use of socially significant symbols to mediate our interactions with the world and each other, enables us to discover and co-opt the survival strategies of any other form of life on the planet, making us the most adaptable species to have ever evolved.  We're the only species that can survive in the vacuum of space, the intense pressures of the deep sea, the freezing cold of Antarctica, and the blazing heat near an active and erupting volcano.  True, we need technology to do all that, but still, we can do it.  It gives me hope that no matter how short-sighted we are, we won't actually be able to destroy ourselves and that we stand a chance of attaining our collective destiny.
