And biological diversity has not remained unalatered since life began on earth. Habitats are under threat all over the world. There are over one-half dozen main causes of biodiversity loss, of which, those related to partial or total destruction of habitats are the most serious. Biogeogrphical barriers have been broken producing problems of invasions of organisms. Another important factor is exploitation of natural resources.
Climate change can also effect biological diversity in several ways.
Finally, rapid population growth effects diversity through the use of the world's resources. One attempt to track biodiversity is the funding of programs which have developed data banks cataloging animal and plant species in various areas of Mexico. One of the very important products of this effort is a map which sets priorities for conservation in Mexico.
