(2) Human life and production activities should proceed from the perspective of maintaining the sustainable development of the biosphere and act according to the development law of the ecosystem.

In the ecosystem, every living thing is an important link in the food chain (net). The defect of one link will affect many links. If we can't strengthen the protection of species,
