Model Answer A: IELTS Band 5+
The question of whether or not we should try to save endangered species is definitely a controversial one. Although some people argue that these animals are not useful and that we should let them die out in the same way that many others (like the dinosaurs) have died out before, I personally believe that endangered species are actually worth saving. There are two main reasons for this.
First of all, it is important for us to recognise the key role that endangered species play in nature. The environment is made up of fragile ecosystems, where plants and animals all rely on one another to survive. If one animal disappears or a new one is introduced, it upsets the balance of nature and affects other animals above and below it in the food chain by changing the environment that they live in. These changes often come back to affect us in ways that we do not expect. In the same way that rabbits introduced to Australia by the British now eat the plants that many native animals need to live and ruin farmers crops, the extinction of a predatory animal would allow its prey to reproduce out of control and would probably cause plagues. Thus, because environmental change is actually a danger to us, we clearly have an interest in saving endangered species.
However, maybe the strongest argument for saving endangered species is that all life is valuable in and of itself. Even if these animals do not have any practical use, they should still be saved. Furthermore, because human activity has destroyed the natural living environment of many endangered species, we should do the best we can to save them.
To conclude, I feel that endangered animal species are indeed worth saving. They not only have their own value, but the balance of nature would be disturbed if they died out.
