三年级英语作文范文：人与自然

　　There is no doubt that human activity has an effect on the planet. We see the evidence of mankind’s 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 world’s animals for the following reasons. First, mankind’s need for land is constantly growing. If the demand is not checked controlled in some way, humans will eventually develop all of the earth’s 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 world’s endangered animals are an important resource and we should protect them by setting aside some land for them. Although mankind’s 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.

　　毫无疑问,人类活动对地球有影响。我们看到了人类的努力在我们周围的证据。总体看来,人类活动危害地球超过好处。生动地背叛了在上面的照片,由于在发展,有限的土地被拨出濒临灭绝的动物。

　　绝对,我们应该保留一些土地给世界的动物,原因如下。首先,人类对土地的需求不断增长。如果不检查的需求控制在某种程度上,人类将最终开发所有可用的土地。那时候,人类将没有更多的发展空间,和所有的野生动物将会消失,以及其他有价值的资源。其次,人类可以创新并且可以使用他们已经拥有的土地,更高效的方法。动物是无法做到这一点。一旦土地被远离他们,他们就会死亡。第三和最后,濒危动物是地球生物多样性的重要组成部分。如果它们消失了,我们无法预测将会造成什么样有影响。因此,我们应该把这些动物视为需要保护的珍贵资源。

　　总之,世界上濒危动物是一项重要的资源,我们应该保护他们,为他们留出一些土地。尽管人类对土地的需求继续增长,人聪明,发明足以使土地正常投入使用。通过这种方式,我们可以有足够的农业用地,住宅和工业和保护地球的生物多样性在同一时间。
