Summary Introduction
Introduction: Declination of biodiversity on the world’s ecosystem can be due to the influence of human activities. There are many other causes like loss and alternation of the habitats, introduction of genetically-modified organisms and exotic species, pollution, and climatic changes. Mostly, the threatened species become endangered in the near future due to some environmental causes and human activities.
