The natural environment encompasses all living and non-living things that occur naturally, and includes complete ecological systems without human intervention as well as universal resources like air and water. It can be distinguished by components like ecosystems and natural resources. Many animal species are becoming extinct at unprecedented rates due to habitat loss and other threats. Several endangered species in Asia are described such as the Kashmir stag with a population of only 160, the golden langur found in India and Bhutan, the red panda found in the Himalayas, and the snow leopard a large cat found in Central and South Asia that is endangered. Conservation efforts aim to protect these and other threatened wildlife.
