Another image that will never leave me is the carcasses of the animals by the roadside. They look as though someone has punctured a balloon and simply deflated the beast. Sometimes, the vultures have had their way and there is a rack of bones on the shoulder of the road. In a society where livestock are a major source of wealth, the animals that fall to disease or injury or accident are left to natural decomposition. And in countries where animals share roads with humans, the end of life is in your face at the roadside, reminding you of how fragile life is.
