The Conservation Status of Biodiversity is usually known through the comprehensive Inventory prepared periodically by the IUCN, the International Union for the Conservation of Nature and Natural Resources. This comprehensive Inventory of the Conservation Status of Species is popularly known as the Red List or the Red Data List.
Substances that are thrown out to some place due to their uselessness or excreted out of our body are called as waste substances.
The conservation of the environment implies the sustainable use and management of natural resources, including wildlife, water, air, and earth soils.

Ozone absorbs ultraviolet radiations so that much of it is never allowed to reach to the earth surface. The protective umbrella of ozone layer in the stratosphere protects the earth from harmful ultraviolet radiations. Ozone plays an important role in the biology and climatology on the earth’s environment. It filters out all the radiations that remain below 3000Å. Radiations below this wavelength are biologically harmful. Hence any depletion of ozone layer is sure to exert catastrophic impacts on life in the biosphere.
