I think Mencius was an early Chinese person who had the idea of ??harmony between man and nature.

If it is not contrary to the farming season, the grain will not be enough to eat; if a few grains of grain are not put into the sandalwood pond, the fish and turtles will not be enough to eat; if the ax and catty are brought into the forest at the right time, the wood will not be enough to use. The grain, fish and turtles cannot be eaten, and the wood cannot be used. This is to keep the people alive and die without regret. Maintaining one's health and losing one's life without regrets is the beginning of the king's way. ——"Mencius, King Hui of Liang, Part 1"

Mencius advocated saving resources and protecting the sustainable development of the ecological environment, which is the idea of ??"timely nourishment". Mencius advised people not to use dense nets to catch fish, so as to leave smaller fish to continue to grow and reproduce; to cut wood should follow the prescribed seasons and follow the nature of nature to meet the needs of continued use. Mencius taught people that the growth and reproduction of all animals and plants follow ecological laws that follow seasonal changes, so they must comply with the laws and do not try to break them. Furthermore, people must follow the ecological laws of growth and change of all things and carry out agricultural production, cutting and harvesting, fishing and hunting in a certain time sequence, and obtain living materials in an appropriate manner. They must not take excessively or use without restraint, which will lead to an imbalance in the ecological environment. Towards the end.

If the dog is nourished, nothing will grow; if the dog is deprived of its nourishment, nothing will disappear. ——"Mencius Gaozi 1"

While Mencius emphasized "taking time to enter the mountains and forests", he also emphasized the protection of natural resources. "Conservation" is very important. Not only should we use it in moderation, but we should also try to minimize what people ask of nature and maintain the original appearance of nature. That is what Mencius said: "You can take it, you can take nothing. Taking it hurts integrity; you can take it without it." "With, you can do without, and harm with benefits" ("Mencius Li Lou Xia"), so that all things in nature can flourish, be harmonious and orderly, and maintain a good ecological cycle system.

There are rich ecological ethical concepts hidden in Mencius’ thought, and reviewing Mencius’ ecological ethics is also very beneficial to the ecological construction of today’s society. Mencius told us that while developing the economy, we must pay attention to "keeping up with the times", not only complying with nature, but also protecting nature, pursuing ecological and economic efficiency based on saving resources, energy and reducing pollution, and achieving economic and environmental integration in economic activities. of coordination and unity.
