What do people belong to on earth? Why are there such complicated emotional barriers?

Many people say that people are superior to animals, and they can speak, think, use tools and learn. . . It's all a family statement, and it's just that human beings are talking to themselves. Other animals didn't take part in the statement at all, and how much do people know about animals? These are just the conclusions that people think they take for granted. In my opinion: Difference 1: People are all animals, and animals are not necessarily people. In fact, people are animals. What's the difference? Then why do you have to say there is a difference? Its fundamental purpose, in my opinion, is to look at people as the former emperor did to people. Obviously, he is just a person, but he insists on saying that he is not a person, but the son of heaven, because then he is superior to people and can master the power of life and death of others. The relationship between humans and animals today is very similar to this. Difference 2: Man is the most important animal among all animals. He thinks he is above others and can dominate the fate of other animals at will. Difference 3: Man is the biggest loser of all animals. The wealth (such as oil, etc.) accumulated by the earth for several billion years was quickly dug up by man in one or two hundred years, and the resources obtained from Mother Earth were used as military weapons to bomb Mother Earth itself in turn. Difference 4: Animals will not destroy the earth, but people will, and the crimes committed by people can be borne by other innocent animals first. Under the action of so-called initiative, people have damaged the earth beyond recognition, and many innocent animals have been extinct. In fact, human beings also know that the good days of human beings are coming to an end (not to mention the light energy crisis is enough for human headaches). If humans don't know how to pull back from the brink, give up those unrealistic goals (such as emigrating to other planets, etc.) and don't really safeguard the earth, it won't be long before humans follow the footsteps of other animals and be deleted from the earth. In fact, sometimes I think, isn't everything that human beings do for reproduction? The rapid development of science and technology only provides better conditions for human reproduction. What about exploring the moon? Aren't they all preparing conditions for future reproduction? But human beings are higher animals after all, and being able to think about the meaning of living is the best proof. At the beginning of human birth, living is really for reproduction, but with the development of civilization, the meaning of living is gradually enriched, and more, it is for responsibility. From an early age, students' responsibility is to study hard, husbands' responsibility is to support their families, and wives' responsibility is to have children ... Every social role has its own responsibility; Generally speaking, our responsibility is to inherit civilization and learn more about human beings themselves. People are actually very simple to live, just eat; It is also very difficult for people to live, and there are many responsibilities waiting for you to bear. The meaning of living is to do your duty.
