The Bronx Zoo spans over 260 acres and has 600 animal species. 700,000 people, however, have signed an online petition, asking them to let one animal go. Happy is a 46-year-old elephant and from the tram, people can see her in her enclosure alone, which is the only way she has lived since her companion died 13 years ago. Animal rights activists have long argued she should be released to a sanctuary calling her isolation inhumane. Recently, writer Yashar Ali tweeted an in-depth take on what makes the elephant so miserable and why the zoo might not be interested in changing that.
