Convention on Biological Diversity (also known as the CBD) is an agreement between countries to work together to protect the environment and animals. It was created in 1992 and countries that agree to follow this agreement work together to make sure plants, animals, and their habitats are protected. This agreement is important because it allows countries to come together to find solutions to problems that can damage the environment. It also helps countries share ideas and resources and agree on how to protect the environment.
