Conservation Biology

The study of how to prevent the loss of biological diversity on the planet is called conservation. Biological diversity, also termed biodiversity, consists of various life forms found in a specific location or across the entire planet, including ecosystems, species, populations, and genes. Conservation thus aims to protect the diversity of life at all levels of biological organization.
