What is conservation biology

Conservation biology is the study of the conservation of nature and of Earth 's biodiversity with the aim of protecting species, their habitats, and ecosystems from excessive rates of extinction and the erosion of biotic interactions.

A major focus of conservation biology is the maintenance of the world's biodiversity.
Biological diversity is the product of organic evolution, and biological processes from the molecular level involving DNA to the biosphere are not intelligible without reference to organic evolution.
