It is absolutely necessary for human beings to develop and utilize resources and energy in order to survive, but all development and utilization should be comprehensively and scientifically considered from the balance of the whole nature, especially the ecosystem of the earth's environment, the so-called biosphere, and then the harmony between man and nature can be achieved on the basis of protecting the natural environment and maintaining ecological diversity. At present, we should not only strengthen and expand those ecosystems with primitive characteristics, that is to say, those ecosystems that are less affected by human beings should be protected and artificially rebuilt to maintain their original natural characteristics and maintain the balance of various elements in the ecosystem, but also pay attention to the valuable experience gained by human beings in understanding the toxicity of chemical substances. For various comparative substances, we should consider a safety measure to prevent environmental pollution, and also seek pollution-free production methods to produce non-toxic chemical products. Obviously, this is a suggestion for chemical workers.

On the one hand, we all complain that the environment is polluted, but we have not polluted the environment ourselves! For example, on the one hand, we clamor that smoking is harmful to health, on the other hand, we are producing and selling cigarettes in large quantities. On the one hand, we strongly advocate not littering. On the other hand, we often throw wrapping paper on the ground when eating popsicles. For example, some factory owners decorate their factories beautifully and luxuriously, but they secretly discharge sewage and waste water into the river ... So, although we promote environmental awareness every day, it pollutes the environment and harms living things.

Why are there so many contradictions? In my opinion, the key is that many people don't pay attention to environmental protection. Accuse others of polluting the environment, but forget that you are polluting the environment! Therefore, when promoting environmental protection, we should also add "start with me!" This last half sentence is really rooted in our environmental awareness, so that we always consider protecting the environment in our actions.
