The major causes of losses of species are as follows:
  • Loss of habitat
  • Over-exploitation and hunting animal species for selfishness.
  • Excessive deforestation
  • The introduction of exotic or alien species which cause competition between the new species and local species.
  • Co-extinction where if one species get extinct then other dependent species will also get extinct.
