A biosphere reserve is an area of land or water that is protected by law in order to support the conservation of ecosystems , as well as the sustainability of mankind’s impact on the environment. This means that each biosphere reserve aims to help scientists and the environmental community figure out how to protect the world’s plant and animal species while dealing with a growing population and its resource needs. Biosphere reserves were created by the United Nations Educational, Scientific, and Cultural Organization ( UNESCO ) under a program called Man and the Biosphere (MAB) in 1968. Since its creation, MAB has helped dozens of countries create biosphere reserves. In order to create a reserve, a country must suggest an area of land for the MAB to approve.
