From Asia, Europe, North America, and Africa, zoos around the world perform wonderful conservation services. They protect Earth’s wildlife and educate people about how they can help.
With charitable donations, zoos protect the most vulnerable animals from extinction and foster health and reproduction. Of course, most zoos are only one or two acres large, housing a handful of animals.
Others, however, are massive and are able to protect and keep animals from various environments. With that said, here are the 25 Largest Zoos In The World You’ll Want To Visit.
Located in the great state of Utah, the Hogle Zoo is 42-acres in size. It houses up to 800 animals with over 249 different species. From elephants to tigers to apes and giraffes, they have just about everything.
An old zoo founded in 1897, Como Zoo is in St. Paul, Minnesota and is owned by the city. At only 17 acres, it holds 1,700 animals and 66 different species. They recently rebuilt and expanded their ape and polar bear exhibits. They get about 1.2 million visitors a year. Which makes sense because admission is free. They depend on state funding and charitable donations.
