地球生物多样性正在迅速减少，作为一个直接和间接的人类活动影响（Frankham，2003）。一个未知的但是几个物种已经灭绝，而其他减少人口规模的地方他们在威胁（grenyer等人。，2006）。几个物种现在称为良性的人类为了提高他们的管理和确保他们继续生存（加斯东，2000）。主要的力量导致灭绝的过度开发，引进的物种和栖息地的丧失，污染（Frankham，2003）。这些力是通过人类造成的，并与人类人口的增长与。
人类因素削减物种对民众的大小，他们很容易受随机影响（诺斯，1999）。这些因素包括人口，环境或遗传（如近亲繁殖和遗传多样性和随机性的灾难损失）。甚至如果背后的真正原因是消除人口减少，人口规模小的问题会继续（Frankham，2003）。此外，考虑到物种灭绝和濒临灭绝的数量不断增加，像保护生物学的概念得到了高度的重视。进一步，本文特别尝试揭示在保护生物学的概念。

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.
