Weoften 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 withnature. All the materials we need to live with come from nature, but we shouldalso repay the nature, rather than blindly solicit. For example, we shouldplant more trees and take actions to protect the environment. In addition, wehave to control population. Due to excessive population growth, human beingsrequire much more natural resources than before, which lead to excessivepressure on nature. In order to long-term development, the population growthmust be controlled. We all come from nature which is our homeland, so we musttry best to protect it.
