For the past hundred years, with the tremendous expansion of humanity, massive human intervention in nature is observed. Many people opinioned that, loss of biodiversity is the prime environmental concern. While others argue that, there are a lot of other issues to be handled first about the environment. I completely agree with the former statement that the destruction of plant and animal resources is the principal problem that must get prime consideration. I will elaborate my views by bringing up the points such as ecological imbalance as well as disruption of the food cycle as a consequence of such loss.
