Only by thinking critically and learning broadly can we reduce harm to our mother nature. What’s really green?

What message does the author really want to convey in the unit? Think and share Humans couldn’t live without Mother Nature. We must give priority to her, and then we can survive in a sustainable way. On no account should any activity of environmental protection be conducted by sacrificing our mother nature, such as exploiting wild areas, disturbing the peaceful life of wild animals. Real environmental protection should consider Mother Nature first and then us human beings rather than the other way round. It is essential for us to equip ourselves with adequate knowledge about environmental protection. We should obey the rules of nature instead of protecting the environment out of our own need or by our own assumptions. You cannot really declare any practice “sustainable” until you have done a complete life-cycle analysis of its environmental costs. The admirable goal of living sustainably requires plenty of thought on an ongoing basis.
