Answer 1

A biosphere reserve is an ecosystem with plants and animals of unusual scientific and natural interest. It is a label given by UNESCO to help protect the sites. The plan is to promote management, research and education in ecosystem conservation. This includes the 'sustainable use of natural resources'. If, for example, fish or trees are taken for human use, this is done in ways which least damage the ecosystem.
