There is no doubt that human activity has an effect on the planet. We see the evidence of mankinds endeavors all around us. Overall, it seems that human activity harms the Earth more than benefits it makes. As is vividly betrayed in the photo above, due to over development, there is limited land being set aside for endangered animals.
Absolutely, we should reserve some land for the worlds animals for the following reasons. First, mankinds need for land is constantly growing. If the demand is not checked controlled in some way, humans will eventually develop all of the earths available land. At that time, mankind will have no more room to grow, and all the wild animals will have disappeared, as well as other valuable resources. Second, humans are able to innovate and can use the land that they already possess in more efficient ways. Animals are unable to do this. Once their land is taken away from them, they will die. Third and last, endangered animals are an important part of the biodiversity of our planet. If they disappear, we cannot predict what the effect will be. Therefore, we should treat such animals as a valuable resource to be protected.
To sum up, the worlds endangered animals are an important resource and we should protect them by setting aside some land for them. Although mankinds need for land continues to grow, people are intelligent and inventive enough to put the land into use properly. In this way, we can have enough land for farming, housing and industry, and preserve the biodiversity of the planet at the same time.
