At this bend, Yang Shubao was almost taken to the ditch.

He didn't know how delicious the long-necked antelope was, anyway, the Europeans almost ate them to extinction after they came to Africa.

Africans also know that the long-necked antelope is delicious, but the long-necked gazelle is particularly alert and fast, and the indigenous tribes of Africa can only get a few occasionally, they have no war horses to catch up with the long-necked antelope, and the spears and short arrows in their hands are not a threat to the long-necked antelope group.

Europeans are different, they come with shotguns, horses and hounds.

Until 2015, before the giraffe was listed on the IUCN Red List of Threatened Species, high-end restaurants in Africa had giraffe meat for town dishes.

Another female student raised her hand and stood up: "In other words, we are not protecting the ecology for the sake of the earth as advertised in the slogan, but simply for the protection of us human beings?"

Yang Shubao nodded: "This is an obvious thing, the earth doesn't care how we make a fuss, even if all the nuclear bombs of the human race explode, it is no threat to it, it has time to recover." But human beings are different, once the biosphere collapses, even if human beings are not directly buried in the catastrophe, they will not survive the biosphere to return to normal. ”

A male student raised his hand and said, "Mr. Yang, I think you are exaggerating, even if humans do not destroy the environment, species are still going extinct, I am an environmental engineering student, and we are well aware that the earth is ushering in a new period of crustal activity and climate change." ”

Yang Shubao nodded and said: "You are right, young man, so what we need to do now is not to destroy the environment, but to protect the environment, pollute first and then clean up, it is time for us to clean up our environment." ”

"Species are going extinct, do you think this has no effect on the ecosystem? No," he added, adding: "You know the Olive Tree, right?"

"Yes. Some students nodded, but many more shook their heads.

"The Olive Tree is a very valuable tree on the African continent, it can grow up to 100 feet tall and can have a circumference of more than 10 feet. ”

"These trees are of great quality, delicate in texture, and are of great value both for both ornamental and economic purposes, and they used to be the best raw materials for canoes on the African continent, and our tribe also has a large canoe with an olive tree, which is hundreds of years old. A black student in the front row added.

Yang Shubao smiled and nodded: "Yes, but if you know about it, you will know that it is about to become extinct." In fact, humans have been taking care to protect it, but they have not been able to protect it, because they need the assistance of the dodo to reproduce, but the dodo is extinct. ”

"Why?" asked several people.

"The seed shell of the giant cranial olive tree is very hard, and they can't open the shell to grow on their own, so they need the dodo to feed. After eating the seeds of the Giant Cranial Olive tree, the dodo digests the seed shell, at which point they are expelled into the soil before they can grow. ”

"Is there no way to save them, such as replacing the role of the dodo with other birds, or grinding the seed shells through a physicochemical reaction?" asked Rowling, who was the host.

Yang Shubao nodded and said: "As far as I know, botanists are now looking for spitting chickens to take on this job, but it is not very suitable, and the big cranial olive tree is already very dangerous in short." ”

After a pause, he continued: "This is a clear example of how organisms are not independent of each other, we all belong to the same ecosystem, and every extinction makes the ecosystem more fragile, but there are some that we don't perceive for the time being. The most frightening thing is that the destruction of the biosphere is still in the stage of quantitative change, and we do not know whether quantitative change will lead to qualitative change, and once it does, it will cause ......"

He spread his hands out, and there was no need to say anything about the rest of the words.

Seeing him spread his hands, a golden lion-faced tamarin thought it was for food, it got out of Nicole's arms and crawled and ran towards him, crawling on top of him three or two and poking his head out.

Finding that he had nothing in his hand, the golden lion-faced tamarin sighed, shook his hand and jumped down, landed on the ground, got up smartly, and ran down the stage in a decent manner.

The students on the steps were fascinated by this scene, and some girls with snacks immediately reacted and took them out to show it: "Hey, little marmoset, look at me here!"

The golden lion tamarin ran over happily after seeing the snacks.

The audience was full of exclamations: "Oh my God, this monkey is so clever!"

"How cute, is that smart?"

"Hey, come to me, I've got bananas here. ”

"You don't have bananas. ”

"All men have bananas!"

There are many foodies among college students, especially girls, and they have food to take out in small packets, most of which are fruits.

The other marmosets couldn't hold back, and they jumped out of Nicole's arms and ran into the audience.

There was chaos in the gymnasium, and Yang Shubao hurriedly shouted when he saw that the situation was not good: "Listen to me, listen to me, ladies and gentlemen, please don't make a commotion, don't make a commotion." It's better to make a deal like this, you stop seducing the golden lion tamarin, and I'll give you a shock!"

The members of the school animal protection association and the security guards strengthened the maintenance of order, and the commotion was suppressed for the time being, but many people were waiting for the shock in his mouth.

If there is no shock, they will shake the gymnasium and let Yang Shubao know that the students of Durban University of Technology are not easy to fool!

Yang Shubao waved to the door, and Lucy understood what he meant, so she patted the gorilla's arm and let it go on stage.

The silverback gorilla slowly stood up.

The muscles of the forearm were piled up, and the two fists smashed on the floor one after another, and the floor of the gymnasium shook slightly, and its huge body moved forward with the lifting of the fist, and the muscles on the shoulders and back were like steel poured, hard as a rock, indestructible!

The students sitting near the doorway had their eyes straight: this silverback gorilla is not a model!

The gorilla raised its head and walked forward step by step, with deep eyes, spoken nostrils, stubborn pursed mouth, and short, thick neck, and people who saw this scene had only one thought: the ancient beast walked on earth.

After a short silence, exclamations rang out one after another, and many people hurriedly called: "Hey, Powell, come to the gymnasium, there are fierce beasts to see here! No, it's not a lion, it's a silverback gorilla!"

"Stop eating, come and see, silverback gorilla, alive!"

"Ask him to bring me a piece of fruit. ”

"You want to die fat?"

"I want to feed the silverback gorilla!"

Ignoring the noisy environment, the silverback gorilla walked firmly and forcefully to the podium, and then climbed up with nimble movements that did not match its large size.

The frame of the rostrum made a tooth-sore sound, and the table shook a few times, but fortunately it did not collapse.

Yang Shubao pressed the silverback gorilla's shoulder and smiled: "This silverback gorilla is a lowland gorilla, it does not belong to South Africa, it is protected by the Land Reform Department in conjunction with my reserve, how is it, does it feel good to protect wild animals?"

Someone whistled excitedly, someone waved to the gorilla, someone held a banana and asked, "Sir, I'm going to feed the gorillas, is that okay?"

Yang Shubao waved his hand and said, "No, gorillas don't eat people." ”
