How many zoos are there in the world?

As of now, there are approximately 10,000 zoos and aquariums globally. This number can vary due to new openings, closures, and changes in classification. The majority of these facilities are small, with only a few hundred recognized as major zoos by organizations such as the World Association of Zoos and Aquariums (WAZA). These institutions play a significant role in conservation, education, and research.
