Threats to Biodiversity

Threats  to Biodiversity
Habitat destruction    The tropical rain forest destruction is mainly due to habitat destruction. The causative factors responsible for habitat destruction are :
·          Overpopulation: it is a condition where an organism number exceeds the carrying capacity of its habitat. This term is used for human population. Overpopulation is the ratio of population to available sustainable resources.
·         Deforestation: It is the removal of a forest and the land is used for other purposes. It leads to multiple environmental problems at atmospheric, hydrological  and soil level which ultimately affect the biodiversity. It causes extinction of many species.
