The planet biodiversity is being speedily dwindling as a direct as well as indirect impact of human activities (Frankham, 2003). An unknown however several species are already extinct, whereas various others have decreased population sizes which place them at threat (Grenyer et. al., 2006). Several species now call for benign human involvement in order to enhance their management and make sure their continued existence (Gaston, 2000). The chief forces contributing towards the extinction are habitat loss, over exploitation, introduced species and pollution (Frankham, 2003). These forces are caused through humans, and are linked with growth of human population.
Human associated factors trim down the species to populace sizes where they are vulnerable to stochastic impacts (Noss, 1999). These include demographic, environmental or genetic (such as inbreeding depression and genetic diversity loss) catastrophes and stochasticity. Even in case if the actual reason behind population decline is eliminated, issues related to small population size would even then continue (Frankham, 2003). Moreover, taking into consideration the increasing number of species being extinct and endangered, the concepts like conservation biology has gained high importance. Further, this paper particularly attempts to throw light on the concept of conservation biology.
