Recently I went to the Tsavo National Park in northern Kenya for a film. We set off early for a distant water hole. A huge elephant, covered with dry mud, drank calmly and deeply. He might have traveled 50 km to reach the water. He wasnˈt going to hurry now. Heˈd drink a while and then rest in the shade, and then drink again—or so we thought. What actually happened was that he drank deeply and stepped away. Then he suddenly fell down. Within minutes he was dead.

We called animal doctor Jeremiah Poghon immediately. He removed the head of a poisoned arrow from the elephantˈs body, and let out over 100 litters of pus(脓)—the result of the elephantˈs meeting with a poacher(偷猎者) months before.

Todayˈs poacher shoots from a blind. He fires an arrow, covered with poison, into the body of an elephant. If the poacher is lucky, the elephant might die in an hour or two; if not, he might have to follow the elephant for days before it dies. Often the arrow head fails to kill the elephant at once—it doesnˈt mean the poison wonˈt finally kill the elephant, but it will be a slow death. Living in Tsavo through these times, I could see the results of poaching from time to time.

When I think about the death of that elephant, what stays with me is the extraordinary silence after the shocking sound of his body hitting the ground. I took some comfort from the knowledge that as the dead body returned to the soil, some animals would benefit—but I couldnˈt escape the feeling that with the death of such a large animal, the world seemed a poorer and emptier place.
