It is derived not from science but from 19th-century religion, and it collapses as soon as we ask a few questions. Anthropomorphism, epitomized in Bambi , is the practice of ascribing human properties, faculties and emotions to non-human organisms.
Predators help control the size of their prey populations.
Without predation, prey populations would grow so quickly that the ecosystem would suffer. For example, in the early 1900s, the ranchers in the Kaibab plains near the Grand Canyon killed many of the local wolves and coyotes. Without these predators, more deer survived. After several years, there were so many deer that food became scarce and thousands of deer starved to death. Predators and prey need each other to keep their populations in balance.
