Biodiversity is a scientific term that is now commonly used.
Put simply, biodiversity means the variety of living things on earth. Anyone who cares about the trees and open spaces around us, or enjoys feeding and watching birds in their garden, is appreciating biodiversity. Biodiversity provides the raw ingredients for our quality of life, our food and clothing, health and relaxation. We don't yet know the full value of some species, for example some plants may have potential for treating cancer and others may have agricultural importance. Research has shown that a rich and natural environment is important to promote human health both physically and psychologically.
