Should societies try to save every plant and animal species? I agree insofar as we humans have moral duty to be responsible for the anthropogenic factors which endanger these species, while it is irrational and impractical to undertake this action regardless of the expense to human effort, time and financial well-being.

To some extent, it is we human beings that bring about the extinction of a series of species. While it is no doubt that nature select concerning evolution plays an important role in the extinction of many species, we human being have long been accelerating its speed drastically, by polluting the invulnerable environment and overly hunting profitable species upon which many predators feed. We need look no further than the fact that many special species, such as a bird named Dodo, have disappeared after the European colonists landed on Mauritius. As we human being has done something culpable that harm the habitat of the plants and animals or even has slaughtered them relentlessly, we are not vindicated thus ought to assume the responsibility to expiate our guilty by trying every means to protect the animals and plants which may thrive without our negative influence.

However, to protect the plants and animals regardless of the expense may amount to no avail. As we all know, all the species are knitted to an intricate web by relationship of predator and prey. So any sharp decline of the number of a certain species will set into motion insessant vicious calamities that are beyond the control of human beings as a species in that web. Once the environment is destroyed or once they are to extinct, we can do little to impede such trend. That doesn't mean that we should refuse any expense on protecting the animals and plants, rather than restoration, it is more practical to safeguard them in a natural way and to restrict ourselves not to harm the species and their habitat.

Moreover, it may be insane to safe every plant and animal irrespective of the expense in effort, time, and financial well-being. Such statement assumes that we human beings have the capability to do so with few risks. However, social situation informs us that there are other trying issues to be addressed, such as hunger, warfare etc. Imagining that a worldwide war is brought up, its damage will not be confined to the human society, but spread to the environment which the innocent plants and animals rely on. Thus the effectiveness of species-saving will greatly shrink. So in this sense, we should strike a balance between species-saving and other competing interests when deciding how to allocate the fund and investment.

In sum, we should assume the responsibilities of protecting the endangered plants and animals whose extinction is on the edge due to detrimental anthropogenic forces. Meanwhile, we should come up with a more advisable and practical way to take advantages of the fund effectively at the stake of the fewest risks.
