Biodiversity is the variety of the earths living organisms, the genes they contain and the ecosystems they compose. This includes the different species of plants, animals and microorganisms that make up an ecosystem. Biodiversity is a key element in the earth’s biosphere- the capability of earth and its atmosphere to support life- due to the earth’s dependency on the maintenance of biodiversity and other non-living objects. This is why the preservation and knowing the threats to biodiversity is highly recommended, as we ourselves depend so heavily on biodiversity and can help maintain it for future generations. Although, before knowing the threats we must first identify the different aspects of biodiversity. Generally there are three levels of Biodiversity Although some researchers argue there are more levels most generally believe that the 3 levels given are an appropriate amount to work with. Genetic Diversity is the variations of genetic composition within a living species. For example all organisms that reproduce sexually, each individual member of that species have a different genetic composition to another member of the same species. This difference between members of the same species is determined by Genes, which consist of Deoxyribonucleic Acid or DNA. DNA determines organism’s physical characteristics (for example in humans DNA would determine a persons eye/hair/skin colour) and their abilities or inabilities.

Earth is the one and only planet that has the life . It has not only life but also variety and variability called as Biodiversity .  A number of plant and animal species make the earth more beautiful .
   But the valuable species are extinct from each by the human activities . Human greed spoils the biodiversity and makes an evil spot on nature face . We must realise from this mistakes and try to save the world .
  Still we have a lot of time and chance to save the biodiversity . We must take some steps and action plans to save this wild . We must agree that we are part in nature . It is for our need not for greed .
