What is biodiversity. Why it is important to conserve biodiversiy ?

Biodiversity is defined as the combined diversity at all levels of biological organization.

There is no exact answer to the question 'why it is important to conserve biodiversity', but experiments conducted by many ecologists have demonstrated that a system with greater biodiversity is more stable and has greater productivity. In the long run, biodiversity is related with overall health of our ecosystem and survival of human race on the earth.

Biodiversity is the diversity of life in an area. There are three kinds of biodiversity. One type is genetic diversity which is the diversity of genes in a species. Species need certain genes to survive. If the diversity is lacking, the species may die, and its numbers will diminish. Species diversity (another kind of biodiversity) is the variety of living things in areas such as rainforests, reefs, deserts, tundra, etc. The last type of biodiversity is ecological diversity. It’s the complexity and richness of an entire ecosystem.

Biodiversity increases ecosystem productivity; all of the species in that ecosystem, no matter their size, have a big role. A diverse ecosystem can prevent and recover from lots of disasters. Humans depend on plants and animals. For example, one quarter of all prescription medicines in the U.S. have ingredients from plants.  If a diverse ecosystem is more productive, it's easier to get these plants.

Biodiversity is the degree of variation of life forms or the variety of living organisms within a given ecosystem which can be aquatic or terrestrial ecosystem.

plants and animals ocur in biodiversity. they are important for our survival. as trees gives us food, oxygen, medicines etc.

animals also give us food as milk, meat, eggs etc.

so we need to conserve biodiversity.

Biodiversityis the degree of variation oflifeforms within a givenspecies,ecosystem,biome, orplanet.

"Biodiversity" is most commonly used to replace the more clearly defined and long established terms,species diversityandspecies richness. Biologists most often define biodiversity as the "totality of genes, species, and ecosystems of a region".An advantage of this definition is that it seems to describe most circumstances and presents a unified view of the traditional three levels at which biological variety has been identified:

  • species diversity
  • ecosystem diversity
  • genetic diversity

The conservation ethic advocates management ofnatural resourcesfor the purpose of sustaining biodiversity inspecies,ecosystems, theevolutionary process, and human culture and society.
