Abstract

Bio diversity, the diverse kinds of living things evolving over the ages and adapting themselves in a particular habitat, plays an inevitable role in equilibrium and sustenance of a natural ecosystem. It also helps build resilience and stabilization of different species of ecosystem. In general, it tries to remain in a balanced state until and unless some perturbations creep in. Whether it is human caused or not, it entirely has severe effect, creating imbalance in the whole process. In the long run, extinction or endangering of species occurs. These perturbations are often termed as stressors. These stressors, also known as drivers, are either directly human driven or indirectly human driven. Whatever be it, these stressors leave a bad impact in biodiversity or pose as a threat to biodiversity.
