Zoological gardens, commonly known as zoos, are facilities where animals are housed and displayed for public viewing. They aim to educate visitors about wildlife and conservation while providing a safe environment for animals. Zoos often participate in breeding programs to help preserve endangered species and conduct research on animal behavior and health. In addition to showcasing animals, zoological gardens often feature botanical gardens, playgrounds, and educational exhibits. Many zoos, such as the San Diego Zoo and London Zoo, are involved in global conservation efforts, working to protect habitats and promote awareness about the importance of biodiversity.
