Animal or plant speciesâ€™ protection from extinction is beneficial because all species are important for balance in the nature world. Moreover, some animals and plants are key in the field of medicine since they provide raw materials used to produce different drugs. These species may include the African clawed frog that secretes antibiotics, the dogfish shark which has cancer fighting molecules. In addition, chemicals found in certain plants assist in treatment of Hodgkinâ€™s disease and other types of cancers. Also, some extracts from specific and rare marine animals has a unique ability to act as anti-cancer agents. (Cunningham, & Saigo, 2005).
Extinction of some species has varied effects because the balance of nature will be broken. For example, a breach in a food chain may cause a drastical increase of some species in over a short period since there will be no consumers in the ecosystem. This growth leads to increased competition for food and space causing starvation ad leading to a disbalance. The predators will also experience lack of feood, and as a result, they will starve to death, which may cause the possibility of their extinction.
The elimination of one organism from an ecosystem, therefore, serves as a domino effect causing the disappearance of other numerous organisms. The introduction of new cloning technology will further accelerate the process of extinction since the easier it is to clone an organism, the lesser efforts are directed towards the protection of the whole species (Ehrlich, 1983).
Extinction is irreversible as a species that becomes extinct is lost forever, and thus, the expensive efforts required to protect animals facing extinction are justified. Protection of different rare and endangered species is achievable. As a solution to this global issue, an investment of 0.1% of global GDP in environment protection will ensure the pay off a large chunk of the ecological debt (Ehrlich, 1983).
