BBC Earth: "The lives of these elephants is dominated by wet and dry, the seasonal cycle created by the sun."
Me: Yes, indeed. Most of the Earth is dominated by the sun. And some other facts of happenstance like how much carbon, water, and nitrogen there is here. But there is one major exception: human beings. The role that the sun -- and those other facts -- plays in our lives is dwindling as we gain more control over our environment. We now have electric lights, sun screen, air conditioning, roofs, and so on. We can go outside when it's very hot, or very cold. We are becoming ever less parochial. Elephants are not.
