In ZOO With Predators, Argentina

Keeping animals in zoos raises concerns for animals rights.
Etymology
London Zoo, which opened in 1828, first called itself a menagerie or "zoological garden," which is short for "Gardens and Menagerie of the Zoological Society of London." The abbreviation "zoo" first appeared in print in the UK around 1847, when it was used for the Clifton Zoo, but it was not until some twenty years later that the shortened form became popular in the song "Walking in the Zoo on Sunday" by music-hall artist Alfred Vance. The term "zoological park" was used for more expansive facilities in Washington, D.C., and the Bronx in New York, which opened in 1891 and 1899 respectively.
