Biosphere reserves are meant to _________.

Biosphere Reserves are sites for experimenting with and learning about sustainable development. There are three main parts to a reserve. The first part is called the core zone, which is strongly protected for the conservation of biological diversity to make sure that different types of plants and animals are safe from human impact. The second part is called a buffer zone and surrounds the core zones and provide a space for environmental research, recreation, and tourism. The last part is called a transition zone  and this area is for local communities that have  hand in managing the resources of the area through farming, fisheries, and other non-governmental activities. Ultimately, the ways that these three zones operate depend on the specific needs of the biosphere reserve they are in.
