According to Infova Foundation Approach:- Biological diversity – or biodiversity – is the term given to the variety of life on Earth and the natural patterns it forms.

The biodiversity we see today is the fruit of billions of years of evolution, shaped by natural processes and, increasingly, by the influence of humans. It forms the web of life of which we are an integral part and upon which we so fully depend. This diversity is often understood in terms of the wide variety of plants, animals and microorganisms. So far, about 1.75 million species have been identified, mostly small creatures such as insects. Scientists reckon that there are actually about 13 million species, though estimates range from three to 100 million. Biodiversity also includes genetic differences within each species – for example, between varieties of crops and breeds of livestock. Chromosomes, genes, and DNA-the building blocks of life-determine the uniqueness of each individual and each species. Yet another aspect of biodiversity is the variety of ecosystems such as those that occur in deserts, forests, wetlands, mountains, lakes, rivers, and agricultural landscapes. In each ecosystem, living creatures, including humans, form a community, interacting with one another and with the air, water, and soil around them.

It is the combination of life forms and their interactions with each other and with the rest of the environment that has made Earth a uniquely habitable place for humans. Biodiversity provides a large number of goods and services that sustain our lives.

Our need for pieces of nature we once ignored is often important and unpredictable. Time after time we have rushed back to nature’s cupboard for cures to illnesses or for infusions of tough genes from wild plants to save our crops from pest outbreaks. What’s more, the vast array of interactions among the various components of biodiversity makes the planet habitable for all species, including humans. Our personal health, and the health of our economy and human society, depends on the continuous supply of various ecological services that would be extremely costly or impossible to replace. These natural services are so varied as to be almost infinite. For example, it would be impractical to replace, to any large extent, services such as pest control performed by various creatures feeding on one another, or pollination performed by insects and birds going about their everyday business.

“Goods and Services” provided by ecosystems include:

  • Provision of food, fuel and fibre
  • Provision of shelter and building materials
  • Purification of air and water
  • Detoxification and decomposition of wastes
  • Stabilization and moderation of the Earth’s climate
  • Moderation of floods, droughts, temperature extremes and the forces of wind
  • Generation and renewal of soil fertility, including nutrient cycling
  • Pollination of plants, including many crops
  • Control of pests and diseases
  • Maintenance of genetic resources as key inputs to crop varieties and livestock breeds, medicines, and other products
  • Cultural and aesthetic benefits
  • Ability to adapt to change
