Rain falls and the flowers bloom. No rain, they wither up. Bugs are eaten by lizards, lizards are eaten by birds. But in the end, every one of them dies. They die and dry up. One generation dies, and the next one takes over. That's how it goes. Lots of different ways to live. And lots of different ways to die. But in the end that doesn't make a bit of difference. All that remains is a desert.
