Ye Xiaoyao also felt that there was no connection, but he still stood on Zhao Weitong's side and said: "Be quiet, be quiet, what are you yelling about, if you don't want to stay, you can go out!"

When the classroom was quiet again, Zhao Weitong spoke again.

"It doesn't seem like there's a connection, but it's very connected. Zhao Weitong said lightly: "Human beings can destroy nature like this without a strong body, when human beings not only have the ability to destroy natural resources, but also have the ability to destroy the ecological balance?"

No one answered this question.

"If you had animal genes and became a human who could strangle an African lion on your own, wouldn't you want to feel what it was like to defeat a beast?" Zhao Weitong continued.

This question caused the boys in the classroom to discuss, and they did have this thought, after all, everyone wanted to feel the feeling of dominating a "powerful species".

"It's not a few people who think this way, it's a majority. Zhao Weitong said: "Maybe in the blink of an eye, only humans and animals domesticated by humans will be left in this world, and other animals will be extinct." ”

"Not really......"

"Yes, we're not barbarians anymore. ”

"We are all new human beings in the age of civilization. ”

The discussion began again.

Zhao Weitong accepted everyone's discussion before asking, "Do you think you are all civilized human beings? Do you think you are not barbaric human beings? Do you think you are all kind and not cruel at all?"

The discussion stopped.

Zhao Weitong suddenly became serious: "In fact, everyone is not kind, we are accustomed to enduring 'cruel' things every day, this is the most cruel place for human beings." Have you ever understood how humans tame animals? Do you really think that all domesticated animals are docile from the beginning? No, it's not like that at all, every animal that humans domesticate is cruel! The process of domestication is also cruel! Of course, you can think that this is what human development needs, and I have nothing to say. ”

Ye Xiaoyao was a little stunned when she heard this, she really didn't think that it was cruel for humans to domesticate other animals.

"Do you know where the milk we drink now comes from?" Zhao Weitong said. Cows continue to be pregnant and give birth to calves to have a steady stream of milk, so these cows have been in the days of pregnancy and milk since they can give birth to death, and the cycle is continuous, and their children have no chance to eat milk, because those newborn calves are very valuable, their life is very short, they are locked in wooden boxes at birth, and they don't even have the opportunity to see anything outside the wooden boxes, because calfskin shoes, leather sofas, leather coats, and leather seats are the most comfortable, and the meat of calves is the most tender, and the tender veal will be sent to all restaurants around the worldEvery one of us has eaten tender beef in a hot pot restaurant, right? We've all eaten steak in a Western restaurant, right? We've all worn leather clothes and shoes, right? If you say no, you've always drunk milk, right? Because you want to drink milk, those calves don't drink it, so they can only be slaughtered and become a meal, so as human beings, we really don't have the right to think that we are good, even if everything we do is normal evolution and has to exist. It is a cruelty for any kind of animal to be domesticated and raised by humans, because once it is domesticated and raised, it means that it will become a normal meal for human beings, from birth to becoming food, how many animals have a short life span is incredible? The normal life span of a cow is 30 years, but human beings can shorten the life of a calf to three days in order to eat the tender beef of a calf, because humans have domesticated cattle, they can raise and control the breeding of cattle, and they can shorten the life span of this animal without any scruples. Isn't that cruel enough?"

The whole classroom was silent.

There was a girl who was drinking a carton of milk, her hands trembled, and she felt that what she had just drunk was not milk, but life.

"Maybe human beings don't need to blame ourselves for this, because we are human beings. Zhao Weitong said: "So we are accustomed to it, and slowly accept this kind of cruelty, which is no longer cruel to humans, but in fact it is cruel to those animals, and things that don't matter to us still matter to other animals." ”

Ye Xiaoyao nodded vigorously.

Zhao Weitong smiled: "Of course, don't think that human beings are too evil like this. ”

"This is what human development needs, and this is something we cannot control. Someone chimed in.

"That's right, that's something we can't control. Zhao Weitong said: "However, now that someone wants to use animal genes to change the direction and speed of human evolution, what kind of disaster will this cause?"

No one spoke.

There really is no one who dares to imagine it.

It's just unimaginable.

In the process of slowly evolving over the years, human beings have done so many things that are "cruel" to other animals.

These "cruelty" will evolve over time, making people feel less cruel and take it for granted.

But what about Professor Conda after he changed the direction and speed of human evolution?

Some "cruel" things that human beings do will not become accustomed to with the passage of time and slowly evolve, but will lead to unimaginable consequences.

"I know you can't imagine it, but I can't imagine it. Zhao Weitong said: "I am a student of biology, I can't imagine that kind of disaster, let alone you." ”

There was silence in the classroom.

Zhao Weitong knew that this atmosphere was not good, so she smiled and ended her topic: "Okay, I won't say more, you don't have to be nervous." ”

"Although I know that each of us understands it differently, I will say now that those who can still accept Professor Conda's ideas can leave immediately. Ye Xiaoyao raised his voice: "I don't need to say this, you will also take the initiative to go." ”

Then, sure enough, three people got up and left, two boys and one girl.

Ye Xiaoyao was a little unhappy.

Zhao Weitong is quite accustomed to it, because she knows very well how attractive the ideas put forward by Professor Kangda are, so she knows how terrible this kind of view is once accepted, and she is not surprised that some people choose to leave without being convinced.

"Cruel people can continue to leave!" Ye Xiaoyao reminded again.

Now no one chooses to leave anymore, Zhao Weitong looked at the people in the classroom, and she was very relieved to be able to stay so much.

"Okay, lock the door! The next song we are going to write is to oppose Professor Kangda's kind of thinking!" Ye Xiaoyao said: "We want to make everyone realize that changing the natural evolution and changing the world will only kill themselves! This is a very serious matter! I never thought that we could make music and influence all mankind, and today we should be proud and proud that we have the opportunity to participate in this creation! To hell with those who leave!"

"To hell with them!" everyone's sense of mission instantly rose.
