Man and Nature
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.
