The correct answer is: A. Man and biosphere
MAB stands for Man and Biosphere. It is a UNESCO programme that aims to promote the conservation of biological diversity and the sustainable use of natural resources. The programme was established in 1971 and currently has over 600 biosphere reserves in over 120 countries.
Biosphere reserves are areas of land or sea that are designated for conservation and sustainable development. They are managed by a partnership of local communities, governments, and scientists. Biosphere reserves play an important role in protecting biodiversity, promoting sustainable development, and educating the public about the importance of conservation.
Option B is incorrect because it does not include the word “biosphere.” Option C is incorrect because it does not include the word “man.” Option D is incorrect because it does not include the word “biosphere” or “man.”
