Biodiversity refers to the variety of life. It is seen in the number of species in an ecosystem or on the entire Earth. Biodiversity gets used as a measure of the health of biological systems, and to see if there is a danger that too many species become extinct.

The number and variety of plants, animals and other organisms that exist is known as biodiversity. It is an essential component of nature and it ensures the survival of human species by providing food, fuel, shelter, medicines and other resources to mankind. The richness of biodiversity depends on the climatic conditions and area of the region. All species of plants taken together are known as flora and about 70,000 species of plants are known till date. All species of animals taken together are known as fauna which includes birds, mammals, fish, reptiles, insects, crustaceans, molluscs, etc.

Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.

A healthy biodiversity provides a number of natural services for everyone:

• Ecosystem services, such as
  • Protection of water resources
  • Soils formation and protection
  • Nutrient storage and recycling
  • Pollution breakdown and absorption
  • Contribution to climate stability
  • Maintenance of ecosystems
  • Recovery from unpredictable events
• Biological resources, such as
  • Food
  • Medicinal resources and pharmaceutical drugs
  • Wood products
  • Ornamental plants
  • Breeding stocks, population reservoirs
  • Future resources
  • Diversity in genes, species and ecosystems
• Social benefits, such as
  • Research, education and monitoring
  • Recreation and tourism
  • Cultural values
