How do people and animals develop in symbiosis?
The fate of man and animals is closely related
Since human collecting society, the fate of human beings is closely related to animals. Animals have gradually become prey of human beings, and then domesticated by human beings. In the long process of symbiosis and coexistence, human beings have successfully reached the top of the food chain with their own wisdom. From the early weak predators gradually become predators, breeders.
Man and animal are interdependent symbiosis
Human and animal are a kind of interdependent symbiosis. People's care and care for companion animals can be regarded as an extension of human external emotions. In order to survive and develop sustainably, human beings must deal with the relationship between human beings and other animals, and realize that human beings are only a part of the whole natural ecosystem.

What diseases do people and animals have in common?
At present, more than 1000 major human pathogens have been found, more than 60% of which are from animals (more than 800 species). According to statistics, between 1996 and 2004, nearly 70% of new and recurrent human infectious diseases were from animals. Zoonosis has become an extremely serious public health problem of global concern. Specifically, zoonoses can be divided into three types: viral, bacterial and parasitic.

How to protect human health?
Protect ecosystem balance
We should not only protect the homeland that human depend on for survival and development, but also carefully protect the habitat and ecological environment of animals, especially wild animals. Only by protecting them and maintaining ecological balance can we effectively cut off the transmission of diseases. Therefore, from the perspective of protecting species and human health, we must put an end to illegal killing, trafficking and eating of wild animals.
Development concept of "one health"
The international development concept of "one health and one health" may be the best way to solve the problem of coordinated development of human, animal and environment. We should learn from the lessons, advocate the harmonious coexistence of human, animal and environment, take the same health as the concept, further strengthen and improve the construction of public health system and biosafety system, care for animals, and prohibit eating wild game.
