Live Future 2000

Chapter 386 In-depth Academic Discussion
Li Lechen heard Wang Jin's footsteps when he first arrived in the community, and also heard him inquiring about his own unit in the community, so naturally he was not surprised at all when he knocked on the door.

So when Wang Jin came in, Li Lechen only paused for a moment, and then continued to clatter on the keyboard.

Zhou Mi welcomed Wang Jin to the living room, and was about to call Li Lechen, but was stopped by Wang Jin: "Don't disturb him."

Afterwards, the two entered the study room together, and they saw Li Lechen seriously looking at the computer.

Wang Jin nodded happily.

Zhou Mi looked up to the sky and rolled her eyes.

After Li Lechen came back from the hospital, anyway, he was either sleeping or playing games, so he probably was about to drop out of school.

It was really a waste of my hard work. I took notes carefully in the past two months, and even prepared an extra copy of the usual test papers.

Seeing Wang Jin's appearance, Zhou Mi didn't bother to expose it. Seeing Wang Jin sitting down on the small sofa in the study, she also sat beside him.

I saw Wang Jin take out a stack of papers from his arms, on which he printed an article on the No. [-] imitation Song Dynasty, to be precise, it was a small half of the paper, entitled "The Impact of Human Activities on Biological Evolution".

Zhou Mi was a little puzzled.

It looks quite esoteric, are you planning to come here to discuss academics with Li Lechen?What's the relationship between them?But it seems that Li Lechen attended Wang Jin's lecture for the first time.Maybe it really mattered.

Wang Jin didn't explain anything, but became excited again when he saw this content again.Although he has watched it countless times, he still couldn't help but read it again. At the same time, he did not forget to point out some key conclusions to Zhou Mi.

Although Zhou Mi made various guesses, her eyes still fell on the paper.

"The evolutionary effects of human activities have gradually appeared on animals and plants. Some are caused by human intervention and climate change on a global scale, and some are caused by local pollution and increasingly dense urbanization. "

".Since ancient times, fishermen have always followed the rule of catching big fish and letting go of small fish. But one point has been ignored by people, that is, small fish do not necessarily grow smaller because of their short growth time, but rather It is because its own traits determine that it cannot develop into a normal individual big fish. This is inadvertently carried out manual selection of "survival of the fittest" again and again, so that some fish species with worse and worse quality are retained."

".In European waters, the size of fish is getting smaller and smaller. It has been observed that the size of some fish has even been reduced by half in the past ten years, and the proportion of small fish in the waters is gradually increasing. Fish The various organs of the human body are also generally shrinking, and the number of fish stocks has decreased by 60%. Pessimists believe that 29% of the fish species currently fished are less than 10% of the maximum level. The author believes that if this development continues If it continues, the global fishery will collapse completely by 2056."

Wang Jin's finger stopped here, and he said, "I've always predicted 2048, but his prediction was 12 years later than mine, but after I recalculated later, I found that it was missing because the government will quickly deplete fish resources. Protective measures will be taken, so the extra 12 years is absolutely appropriate."

"???"

Zhou Mi didn't understand for a while, she was stunned for a long time and asked: "You said these were written by Li Lechen?"

"Of course!"

Wang Jin looked smug, as if Li Lechen was already his favorite student.

Zhou Mi was speechless for a moment, and twitched the corner of her mouth: "Could it be searched on Baidu?"

After all, Zhou Mi got up immediately to see what Li Lechen was doing clacking on the computer keyboard.

Nine out of ten are playing games!

In the end, Wang Jin stopped him again: "Please don't disturb him, it's a terrible thing to be interrupted."

Zhou Mi was helpless.

She has been with Li Lechen for the past few days, and she hasn't seen him doing anything serious in the past few days, but because of her health, everyone indulged her.If you talk about doing academics, it is absolutely impossible.

I just don't know why Dr. Wang Jin is so sure.

There is no way, he has white hair, and he is a Ph.D. from a national scientific research institution. He came to Li Lechen's house so excitedly, and took an article that he might have copied from Baidu. He must think that Li Lechen is a genius. In addition, Zhou Mi is at someone else's house, so naturally she can only follow.

Wang Jin continued to admire the half of the thesis.

".Urbanization is perhaps the most visible impact of humans on the planet. The plants and animals that live in cities are constantly evolving to adapt to the environment that humans have transformed"

".In the city there is a kind of annual chrysanthemum whose seeds grow larger and heavier than their counterparts in the wild. Previously, the seeds of this chrysanthemum were spread by the wind and scattered with the wind. The lighter seeds were originally It is an advantage, but in the city it is the opposite. If it is blown farther by the wind, it is likely to fall on the concrete or asphalt ground in the distance and cannot grow. The seeds become heavier and can fall directly into the soil around the plant , is conducive to the continuation of the population. There are also some weeds that grow in the cracks of the city's masonry roads. Compared with those in the wild, these grasses no longer scatter seeds around. It is foreseeable that by about 2100, more than 80% of the plants will be no longer produce seeds."

Wang Jin again focused on the date of this prophecy.

"This is a bit ridiculous. Plants will become extinct without producing seeds. It will be too exaggerated in less than 100 years."

Zhou Mi didn't know why, but she also saw it when she looked at it.

Wang Jin thought for a while and sighed: "The theoretical basis for this prediction is very sufficient, but the time prediction... I don't know what it is based on."

"It must be a wild guess." Zhou Mi asserted.

"I don't think so. Some people think that this situation will not take 100 years."

"Uh!"

Suddenly, Li Lechen sighed.

Zhou Mi got up quickly, and said with a worried face: "What's wrong?"

"No chicken again!"

Li Lechen was furious and started a round again.

Zhou Mi's face darkened immediately, she was indeed playing a game.

Looking at Wang Jin, he was a little confused.No chicken?What's the meaning?
Oh~~~Right!
Wang Jin's gaze fell back to the paper.

".Not only plants are evolving, but animals are also being forced to evolve due to urbanization. A typical case is the so-called 'industrial blackening phenomenon'. It may be nothing if only the color change, but scientists have also discovered more shocking changes A fish called Atlantic cod lives in the Hudson River in the United States. Due to sewage discharge, there are many toxic pollutants in the Hudson River, and in just a few decades, Atlantic cod has evolved resistance ...it can store toxins in fat without causing damage to itself. This is similar to how insects develop resistance to insecticides and bacteria develop resistance to antibiotics."

"This passage must have been copied from Baidu!"

Zhou Mi pointed out immediately.

Wang Jin nodded his head in a rare way.

However, there are a lot of articles in the world. Such examples are naturally borrowed from existing achievements, otherwise they are all innovations, and the articles are not like articles.
