"Open since the end of the 19th-century, this world-class zoo—at 265 acres, one of the largest on the globe—is home to animals from the far reaches of the planet, including several endangered species and many now thriving rescues. While the idea of keeping animals in captivity can be troubling, we take comfort in the almost true to life quality of the animal's habitats, and the fact that the zoo contributes to important research and the protection of wild animals."
