Every living thing has an important role in keeping the balance of nature. If one species is totally wiped out, it could lead to loosing other species as well. When the prairie dogs were wiped out in the Midwest, the black-footed ferret also was endangered. And if the endangered species is a natural predator, the explosion on the population of their natural preys may also give us a lot of problems. If a certain type of snake that feed on rats is one day wiped out, it could result to infestations by rats into our homes and food source. This happened when the natural habitat of snakes where converted into housing subdivisions. The snakes were eliminated but the rats remained.

Plants and animals are also one of the biggest sources of our medicines today. If these endangered species are gone, we may never be able to find out what could have been their roles in the betterment of our lives. They may hold the cure to the most dreaded diseases man is facing today. If we let these endangered species die, we might as well have let our loved ones die from diseases that these species could have helped in finding cure.
Saving these endangered species is also one of the evidence that the human society has evolved into a better one already. We are no longer the society that takes advantage of the weaknesses of other living creatures for our own gains. Since man pride himself as the most intelligent creature that ever walked in the face of the earth why don’t we show it by using this intelligence for the protection of the weaker creatures. We cannot advance as a civilization while leaving those creatures that helped us behind. As it is quoted, “a society is truly measured on how it treats its animals.”
Lastly, let us reflect that the species that we really are saving could be ours.
