The dictionary definition of zoo is an establishment that maintains a collection of wild animals, typically in a park or gardens, for study, conservation, or public display, but the true definition A zoo it is a place where animals are kept in captivity and kept away from their natural habitat.

The president of the Foundation on Economic Trends, Jeremy Rifkin, wrote an article titled “A Change of Heart about Animals”
