So, the first question arises, Do we know the correct meaning of biodiversity or Are we introduced to the exact definition of the term ‘Biodiversity‘. Biodiversity is commonly used to replace more clearly defined and long defined terms, diversity of species and richness of species.
Biodiversity especially introduced to the variety and variability of life on Earth. Biodiversity is basically measures variation of genetic, species and at ecosystem level.
Marine biodiversity is generally high over coasts in the western Pacific, where surface temperature of sea is highest, with the mid – latitudinal bands in all oceans. Terrestrial is generally greater at near around equators, which results for warm climate and the high primary productivity. As biodiversity is not even distributed clearly on earth, and is richest in the tropics. These ecosystems of tropical forest cover less than 10% of earth’s total surface, and contains near about 90% of the world’s species. There are some latitudinal gradients in species diversity. Biodiversity usually tends to cluster in hotspots, and also increasing throughout time, but will suggesting to slow I’m future.
It is expected to 99.9% of all species which have been ever lives on earth, are amounting to over more than five billion species, are estimated to be extinct. It is suggested on the number of earth’s present species which ranges from 10 million to 14 million, out of which 1.2 million have been fixed documentation and over 86% have not yet been explained. Rapid environment changes usually causes mass extinctions.

Since the life began on Earth, five main mass extinctions and several others events have tends to larger and sudden droplets in biodiversity. Biodiversity is basically not evenly distributed, rather than it varies along the globe as well as within regions. Along some other factors, diversity of all living things totally depends upon temperature, precipitation, altitude, soils, geography and the other present species all over the region. Therefore, this estimate seems to represent under the diversity of organisms.

  • LATITUDINAL GRADIENTS
    • Usually, there is an increase in biodiversity from poles to poles. Thus, species are more  at lower latitudes than at higher latitudes. This is often referred to as latitudinal gradients in the diversity of species.
  • HOTSPOTS
    • A biodiversity hotspot is a region where a high level of endemic species which have been experienced a great habitat loss. This term hot spot was firstly introduced in 1988 by Norman Myers at that time.
  • EVOLUTION
    • Chronology –
      • The origin of life have not been established through Science, where, some evidence suggests which life may already have been well-established only few hundred million years after the formation of earth. This history of biodiversity during the Phanerozoic, started with that rapid growth during the Cambrian explosion.
    • Diversification –
      • Diversification also appears that the diversity continues to increase over the time, especially after mass extinctions.

Cause –

There are always some causes of every unappealing or every processed resultant its same as with causes of biodiversity.
Following are some direct threats as the causes of loss in biodiversity –

  • Residential & commercial development
    • For industrial and commercial areas.
    • For urban areas & urban areas.
    • For recreational areas.
  • Mining & energy production
    • Mining {minerals and fuels}.
    • Non-renewable energy production.
    • Renewable energy production.
  • Usage of biological resources
    • Victimization
    • Fishing
    • Hunting
  • Farming Activities
    • Aquaculture {seeded shellfish beds}.
    • Agriculture.
  • Service corridors & Transportation
    • Collisions with the vehicles using corridors.
    • Service corridors
  • Pollution
    • Households sewage.
    • Excess energy.
    • Air-borne pollutants.
  • Climate changes
    • Changes in temperature.
    • Changes in precipitation.
    • Changes in geographical regimes.
  • Over exploitation
  • Deforestation
  • Invasive species
  • Habitat loss

Therefore, It is concluded that biodiversity is very important for the sake of society.

“Biodiversity is the greatest treasure we have… It’s diminishment is to be prevented at all cost.”
