The Prospect Park Zoo will hold Earth Day events on April 19-20. Visitors can celebrate the wonders of our planet with the animals and take part in a variety of activities. One highlight is the Hamadryas baboon family, including the member pictured with a young zoo visitor above. Children and adults can also learn about the Wildlife Conservation Society's mission to save wildlife and wild lands around the world.
