Four-six-seven jī is a bit difficult, is it okay to change to a rabbit?

As soon as the double monthly pass was opened, it immediately lagged behind one place......

Friends, in the last three days, brother, I will hold it with all my might, I don't know if you can withstand it?

Ask for votes! Ask for a commuter pass! ――

"Rabbit?"

"Put rabbits?"

At the discussion meeting, many people first felt incomprehensible when they heard that the companion named Chi Zhengjie proposed such a proposal. To read the latest chapters, please lock in Aishang Novel Network biquge.info rabbits, which look cute and threatening, can be released into the wild to solve the current problem of food scarcity?

But the xiǎo Chi who proposed this construction yì was xiōng has become bamboo, and he first told everyone a very interesting math problem:

A pair of rabbits that begin to be fertile in the second month after birth, assuming that a pair of xiǎo rabbits are bred every month. Q: How many pairs of rabbits can a pair of rabbits breed in a year?

This is a question about the Fiyō Chena sequence, and the answer is one hundred and forty-four pairs. But in reality, the fertility of rabbits is much higher than that - young rabbits are already fertile after two months of life. The pregnancy cycle of the female rabbit is only 31 days, and it can give birth 4~6 times a year, and each litter is about 6~10 birds...... Therefore, scientists believe that if no measures are taken to limit the reproduction of rabbits in 90 years, then there should be a rabbit standing on every square meter of land on the planet!

Of course, rabbits have many natural predators, and almost all the larger ròu eaters and even birds will make it a top priority in their diets, and they do not have the same strong evasive ability as rats - this species at the bottom of the natural food chain would have been extinct long ago if it had not been for its strong reproductive ability.

But as long as the environment isn't so harsh, give them a little time and space – and of course enough forage – the rabbit population can explode as quickly as possible.

"If we don't want to let the promises made by the head of the Xie regiment to the people be disappointed, we don't just treat them as empty slogans...... It's still a bit difficult to make jī available to every household. But if you replace jī with rabbit, it's completely achievable. ”

Chi Zhengjie used this reason to support his Jianyì, because although Xie Xi withdrew from the committee, he was still the head of one of the main xiǎo groups in the Qiong Navy, and he had a high prestige in the entire Crossing Crowd, and if he expressed his support, there would be a large group of people to support him.

Xie Xi was really a little moved, but the opposition of the surrounding people was also very loud - the rabbit's reproductive ability is indeed super strong, but it is precisely because it is too strong that people feel scared. Once they are allowed to breed on a large scale, who can guarantee that there will be no impact on the island's ecosystem? Ancient China is not without rabbit disasters -- Professor Li Mingyuan is well-informed and strong, citing the record of the "Taiping Guangji" in the Tang Dynasty: "In the year of Yongchun, the rabbits in Lanshengzhou were violent, and tens of millions of people flocked into herds, eating seedlings and ...... them all."

Someone even brought up the famous case of Australian rabbits: in 1859, a farmer brought a few rabbits from a foreign country to raise them in order to hunt. Since they have no natural predators in Australia, their numbers are constantly doubling. By 1950, Australia's rabbit population had grown from five to 500 million, and most of the country's crops and meadows had been devastated.

Australians try their best to fight rabbits: poisonous yào, fence walls, animal predators, but with little effect. In the end, relying on the power of biotechnology, we found an infectious disease that occurred in rabbits, and successfully caused it to explode in the Australian rabbit herd, so as to eliminate more than 90% of the rabbits in one fell swoop, temporarily alleviating the situation.

However, it is only a relief, because the adaptability of the creatures is extremely strong, and some rabbits quickly develop immunity to the virus, and they quickly reproduce after they are lucky to escape. So throughout the 20th century, Australia's rabbit eradication campaign never stopped, costing a lot of money every year.

…………

The consequences of such a strict zhòng made everyone feel terrified, and many people began to express their opposition to Xiǎo Chi's construction yì - it doesn't matter if you eat less, you can ruin the ecological environment, but there is no place to regret it!

But Chi Zhengjie himself was engaged in the research of alien species control before the crossing, and in fact, the Australian rabbit case was only spread by him when he used to tell everyone during the casual chat at the Sleeping Talk. Since he dared to propose this proposal, he naturally had already considered it all:

"Ladies and gentlemen, the case of the Australian rabbit has its own peculiarity - the rabbit is an alien species, and there is almost no natural predator restraint in the local area, so it reproduces very quickly. In addition, Australia's climate is generally dry, and there is a lack of tall trees, and there is generally little green vegetation. However, the local economy is dominated by the sheep máo industry, which itself needs a large amount of pasture support, so the losses caused by the rabbits after the destruction of the pasture are particularly strict......"

As soon as the conversation changed, Chi Zhengjie pointed to the map of Southeast Asia on the wall:

"In Southeast Asia, where there is abundant precipitation, the vegetation coverage rate generally exceeds 70 or 80 percent, and most of the inland areas of Hainan and Taiwan Island are still inaccessible barren mountains and mountains, and there are not too few plants but too many trees. At present, the agricultural group still has to set fire to large areas of forests in the reclamation of wasteland, and even if there are tens of thousands of hundreds of thousands of hares, it will not be wasted, but it can appropriately reduce the difficulty of clearing and weeding in the future. ”

"On the other hand, there were rabbits on Hainan Island before, and there were many natural predators that preyed on them. As far as I have observed over the past few years, the island is very rich in species of ròu eaters such as wolves, foxes, mountain eagles, snakes, etc., and these populations will inevitably increase as the rabbit population increases, so there is no need to worry about the balance between the populations getting out of control. ”

"And ......"

Chi Zhengjie's arm drew a circle in the air and put it in front of him:

"Let's not forget, for other biological populations, we humans are the most terrible natural enemies. Any wild animal, as long as it enters our human diet, is basically reduced to the point where it needs to be protected. When I was studying the case of Australian rabbits, our tutor once said that the main reason for the rampant Australian rabbits is that the local people are generally wealthier and too lazy to catch rabbits for food, so they have to deal with them with money. If it's ...... in our country"

Chi Zhengjie's words resonated with many people, and everyone laughed. As modern people from the twenty-first century, they know all too well how terrible the big mouth of the Chinese is. Xiǎo Chi's mentor is right - if it is in China, the rabbits dare to rebel? I ate it immediately!

Finally, Chi Zhengjie assured everyone as an expert:

"This idea is not new, I have been working on it for several years. Artificially increasing the number of rabbits in the wild may indeed have some impact on the local biological chain - for example, due to the increase in the rabbit population, the number of wolves, foxes and other communities will increase, and the increase of these ròu animals will lead to a decrease in the number of squirrels and other animals...... But overall, the environment on Hainan Island has not changed much because of this. After all, rabbits are not considered an alien species here, not invasive species. Don't worry too much - rabbits breed in most parts of the world, but there are only a few real disasters, and they're all too easy to deal with. At best, we are using nature as a natural farm, using the surplus vegetation of the current islands to feed a fast-growing source of ròu. ”

After Chi Zhengjie's explanation, many people began to tend to accept his opinion again - after all, everyone is a layman in this regard, and Xiǎo Chi is an expert. He said no problem, it should be no problem, right?

After that, Li Jiangdong asked him a question: how to ensure that these rabbits eat weeds honestly after breeding, instead of rushing to the fields in groups to harm the seedlings?

"There's no guarantee of that."

Chi Zhengjie replied very bluntly:

"Rabbits behave very badly, and what they eat depends on their tastes. However, we can provide farmers with a very simple but effective protection......

Chi Zhengjie took out something that looked a bit like a slingshot and showed it to everyone, which was a clip used to set rabbits, the material was very ordinary, and it was made of bamboo and cotton rope. The design is very ingenious, as long as there is a rabbit big xiǎo animal drilling through it, it will inevitably be caught and unable to move.

"It's a rabbit clip, an improved version of the rat slingshot that specializes in mouse hunting. It's simple to make, but it works great. I believe that those farmers would be more than willing to fence off their paddy fields with such clamps and endure some crop losses – as long as they can regularly pick up one or two féi rabbits to take home as a side meal. ”

It makes sense to think about it - there are many factors that have plagued farmers' fields these years, especially for farmers who have migrated from the north, and the losses caused by drought and locust plagues and rat plagues must have been much higher than the legendary rabbit plague. If you can pick up rabbits in your own rice fields, it is not necessarily a bad thing for those farmers.

After that, everyone consulted the opinions of Zhang Mao Huā and Wu Youfufu, who were professional breeders, and they didn't know what names such as out-of-control populations, and they couldn't say good or bad about Chi Zhengjie's construction. But they confirmed that there are a lot of rabbits on the farm themselves - rabbits reproduce super fast, and ròu is not less, but they consume more forage and feed, and they like to play dòng all over the ground a bit of a problem. However, as long as the cage is strong enough, it can actually be raised very well.

In the past few years, there have been several incidents of rabbits escaping from prison, and I have not heard of any disasters in the surrounding area. Therefore, Zhang and Wu did not reject Chi Zhengjie's so-called "Hainan Island as a natural farm", but were a little worried about whether it could be reproduced after it was released......
