We often say that the earth is our homeland and human society comes from nature. Therefore, I think our society is a part of nature. People should live harmoniously with nature. All the materials we need to live with come from nature, but we should also repay the nature, rather than blindly solicit. For example, we should plant more trees and take actions to protect the environment. In addition, we have to control population. Due to excessive population growth, human beings require much more natural resources than before, which lead to excessive pressure on nature. In order to long-term development, the population growth must be controlled. We all come from nature which is our homeland, so we must try best to protect it.

　　 我们常说,地球是我们的家园,人类社会来自大自然。因此,我认为我们的社会是一个自然的一部分。人们应该与自然和谐的生活。所有的材料我们需要接受来自自然,但是我们也应该回报大自然,而不是盲目地恳求。例如,我们应该种植更多的树木和采取行动来保护环境。此外,我们必须控制人口。由于过度的人口增长,人类比以前需要更多的自然资源,自然导致过度的压力。为了长远发展,必须控制人口增长。我们都来自大自然,是我们的家园,所以我们必须尝试最好的保护。
