Talking about what is the way of nature in combination with practice.

Natural laws and natural ways are natural laws. In an example of a joke, it is natural for dogs to bite people, but it is unnatural for people to bite people and dogs, although people can bite people and dogs. The biosphere on earth is a food chain, an energy chain, a material chain and an information chain, and any node in it has special requirements at that position. According to this requirement, that is the way of nature. If you don't follow this requirement, it's against the way of nature. It is natural to explore whether the environment is dangerous and suitable before returning to the sea, and it is also natural to be eaten by hunters as food on the way back to the sea. However, if someone kills a young turtle at will for no bad purpose, it will go against the natural way, just like rabbits in Australia, which will cause a chain reaction in the biosphere.
