When we die, our bodies become the grass, and the antelope eat the grass. And so we are all connected in the great Circle of Life. Everyone knows that classic line from Disney's "The Lion King". Kids and parents might have been slightly less charmed by this variation: The wildebeest must cross the river to eat, and a whole bunch of them die in the process. And then everything in the river gets to feast on their rotting remains. Oh, and their bones continue to leech nutrients into the water even after fish and insects have devoured their flesh. Other organisms also eats the algae that grows on the bones. Basically, some wildebeest need to die, Simba.
