When an animal dies, another of the same species may cling to the body, eat the body, or look bored. Bees expel dead bodies from the hive or, if that is impossible, embalm them in honey. Elephants "say" a ritualistic good-bye, and touch their dead before slowly walking away. Corvids often accept the death of a companion without much fuss, but they at times have “funerals,” where scores of birds lament over the corpse of a deceased crow. But it is a bit odd that people should investigate whether animals “comprehend death,” as if human beings understood what it means to die. Is death a prelude to reincarnation? A portal to Heaven or Hell? Complete extinction? Union with all life? Or something else? All of these views can at times be comforting, yet people usually fear death, quite regardless of what they claim to believe.In the natural world, killing seems a casual affair. Human beings, of course, kill on a massive scale, but most of us can only kill, if at all, by softening the impact of the deed through rituals such as drink or prayer. The strike of a spider, a heron, or a cat is swift and, seemingly, without inhibition or remorse. They pounce with a confidence that could indicate ignorance, indifference, or else profound knowledge. Could this be, perhaps, because animals cannot conceive of killing, since they are not aware of death? Could it be because they understand death well, far better than do human beings?If animals envision the world not in terms of abstract concepts but sensuous images, the soul might appear as a unique scent, a rhythmic motion, or a tone of voice. Death would be the absence of these, though without that absolute finality that we find so severe. Perhaps the heron that snaps a fish thinks his meal lives on, as he one day will, in the form of currents in the pond.
In every remote corner of the world there are people like Carl Jones and Don Merton who have devoted their lives to saving threatened species. Very often, their determination is all that stands between an endangered species and extinction.But why do they bother? Does it really matter if the Yangtze river dolphin, or the kakapo, or the northern white rhino, or any other species live on only in scientists' notebooks?Well, yes, it does. Every animal and plant is an integral part of its environment: even Komodo dragons have a major role to play in maintaining the ecological stability of their delicate island homes. If they disappear, so could many other species. And conservation is very much in tune with our survival. Animals and plants provide us with life-saving drugs and food, they pollinate crops and provide important ingredients or many industrial processes. Ironically, it is often not the big and beautiful creatures, but the ugly and less dramatic ones, that we need most.Even so, the loss of a few species may seem irrelevant compared to major environmental problems such as global warming or the destruction of the ozone layer. But while nature has considerable resilience, there is a limit to how far that resilience can be stretched. No one knows how close to the limit we are getting. The darker it gets, the faster we're driving.There is one last reason for caring, and I believe that no other is necessary. It is certainly the reason why so many people have devoted their lives to protecting the likes of rhinos, parakeets, kakapos, and dolphins. And it is simply this: the world would be a poorer, darker, lonelier place without them.
