Humans have historically tended to separate civilization from wildlife in a number of ways including the legal, social, and moral sense. Some animals, however, have adapted to suburban environments. This includes such animals as domesticated cats, dogs, mice, and gerbils. Some religions declare certain animals to be sacred, and in modern times concern for the natural environment has provoked activists to protest against the exploitation of wildlife for human benefit or entertainment.
The global wildlife population has decreased by 52 percent between 1970 and 2014, according to a report by the World Wildlife Fund. (source: https://en.wikipedia.org/wiki/Wildlife)
