Although we always said that this should not be for natural resources and ecosystem labeled price, in fact it is almost impossible, not to mention those of the industrial and commercial resources, even our most basic physiological needs (such as water, vegetables, meat, etc.) are obtained in nature and ecosystem, and put a price tag for tradings in human society. In my vision, the world has a very reasonable system of balance between human interests and the ecosystem. The value of this is that people can enjoy the resources and value of nature, while ensuring that the process of obtaining them does not cause damage to nature and makes the resources sustainable. In short, it is to make people a part of the ecosystem rather than a mere interference. We should always be in awe of nature when acquiring resources.In order to achieve this goal, I think the government should pay attention to the company, law and related technology and facilities of these resources acquisition. As we talked about water resources in this class, it is necessary to provide corresponding policies for the use and management of water resources. The Earth is a blue planet with very little available fresh water. These kinds of ideas and truths should also be included in advocacy and propaganda so that people can participate and do their part.
