Because seventy to ninety-eight percent of the species that have appeared on the planet have either become extinct or evolved, it is clear that extinction and evolution are natural processes. However the current rate of extinction is highly unnatural. Species should be preserved for economic, aesthetic and recreational, ecological, and ethical reasons.
