Major factors for loss of biodiversity are 

(A) Changes in land and sea use 

(B) Acid rain

(C) Direct exploitation of organism 

(D) Climate change

(E) Ozone depletion 

Choose the correct answer from the options given below : 

Biodiversity loss is the loss that occurs as a result of a drop or reduction in this variety due to a range of circumstances.

Key Points

• The loss of biodiversity in a location may result in the extinction of some species, which in turn may result in the extinction of the entire ecosystem in that area.
• Some of the major factors for the loss of biodiversity: 
  • Natural resources that were limitless a thousand years ago now appear to be severely limited due to the rising human population alone.
  • One of the biggest causes of biodiversity and ecosystem loss is land-use intensification.
  • Overexploitation has resulted in the extinction of species.
  • For Example, Steller's sea cow and the passenger pigeon. 
  • Climate change has an impact on biodiversity on several levels, including species distribution, population dynamics, community structure, and ecosystem function.
• overexploitation of natural resources, which has resulted in the extinction of biodiversity.

Therefore, Major factors for the loss of biodiversity are changes in land and sea use, direct exploitation of organisms and climate change. 

Additional Information

•  Acid rain is a type of precipitation with a pH of 5.2 or below that is mostly caused by human activities such as the combustion of fossil fuels which emit sulphur dioxide and nitrogen oxides. 
• Ozone depletion: The gradual thinning of the Earth's ozone layer in the upper atmosphere is caused by the discharge of chemical compounds containing gaseous chlorine or bromine from industry and other human activities. 

​ Confusion Points

•  Acid rain can affect biodiversity as it can effects fish are harmed or killed, fish population numbers are reduced and fish species are completely eliminated from a waterbody.
