Early in the morning, after Fang Hong got up, he got everything done, and then turned on the live broadcast and set off. Pen & Fun & Pavilion www.biquge.info

"Good morning, Brother Gun. ”

"Brother Gun said last night that you were going to take revenge, but I was waiting in front of the computer early. ”

Fang Hong took out the tools he made early in the morning: "I won't take revenge on this, and quit smoking from now on." ”

"666, Brother Gun, who are you going to hit with a crutch?"

Fang Hong rolled his eyes: "This is a bow, it's a bow, it's a bow! Say important things three times!"

"I'll go, Bow?"

Fang Hong looked at the thing in his hand: "Okay, I admit it's a crutch." ”

Fang Hong regretted this, because Mao didn't bring the bow out.

This thing is a slightly tightened cypress pole with a flexible and curved cord.

The arrows that this thing fired...... It's really hard to say what about sharpened sticks and accurate heads.

"Da Da Da!"

Walking into the mountains and forests, I turned around an area where mountains blocked my view, and suddenly such a sound came out.

Fang Hong turned over his hand and took out his bow and pulled out the wooden stick: "Found it!"

Arriving at the top of the mountain, Fang Hong looked around, and a touch of bright red came into view.

"666, Brother Gun, are you saying that last night's flood was caused by woodpeckers?"

"This pot adheres to Brother Gun's usual habit of throwing the pot, that is, throwing out the pot, and the object of the dumping cannot refute it. ”

Fang Hong rolled his eyes: "It wasn't the woodpecker who did it, I found the wrong one." ”

The woodpecker, which is black all over and has white tail feathers, and a bright red short-haired nose on the front of its head, constantly beats the trunk with its beak.

"Da-da-da!" Basically, there was just over a second between each tap.

"When I used to watch cartoons, I really thought that woodpeckers were like chainsaws, but I didn't expect it to be like this?"

Fang Hong: "Of course, the woodpecker will first knock the pine bark, then peel off the bark, and then burrow from the trunk until it meets the wormhole, and then stick out its tongue to eat the worm. ”

"666, won't you have a concussion?"

Fang Hong didn't know how to explain it, so he took out a piece of line: "The woodpecker's tongue is very long, basically the same length as its body, and when it doesn't stretch out, it will wrap around its nasal cavity." Fang Hong wrapped the arrow with a thread: "Just like this, when you hit the trunk, the tongue is like a shock absorber, protecting its brain." ”

"My tongue is as long as my body, and it sounds funny. ”

"Put away your not pure thinking...... Fang Hong looked at the woodpecker: "This kind of bird grows very slowly, and the young birds have to follow their parents for five years to learn a whole set of predatory skills. ”

"Their beaks grow all the time, but they wear out when they hit the trunk, and the beaks of the older woodpeckers are extremely long. ”

Fang Hong put away the arrows: "It's not them, let's continue to look for them." ”

Skirting the mountain, there is an area like a lake as far as the eye can see.

The lake is lined with stars and moons, and it looks like a huge mirror covered with dust.

"I think we found it. ”

At the far end of the lake, there are tree stumps everywhere, and there are many dead branches in the lake, and you can even see a giant tree that looks like it has been cut down in half.

"These trees, which have nature's strongest ability to protect against cold, are guaranteed to freeze below zero. In winter, the temperature here is almost always more than minus 20 degrees, and the limit is minus 35 degrees. Poor and hard trees, they can only stay where they are, and they will inevitably suffer from poison. ”

"Brother Gun, were these stumps cut down by humans?"

Fang Hong shook his head: "If it is cut down by humans, the next spring, they can still grow branches, in fact, they are cut down by an animal, and if they are cut down by this animal, the veins of the trees will all be destroyed, and they will die." ”

"What kind of animal is so fierce? Is it only the North American brown bear that has this ability?"

"Even three times the size of the North American brown bear, it can't knock down such a thick tree, in fact, it's a small animal, you see in the lake. ”

In the lake, a brown mammal swims in the water.

Fang Hong pointed to it: "The Canadian beaver was introduced to Argentina in 1946 to meet the human demand for fur. However, beaver hats have long since become obsolete, so the demand for fur has dropped dramatically. Of Tierra del Fuego's 48,000 square kilometers, nearly 30,000 square kilometers are covered with snow and ice, while in the eastern, more climate-friendly eastern and northern, it is divided by two river basins, while in the middle, nearly 10,000 hectares, where 500,000 beavers live, are completely out of control. ”

"Out of control, how out of control?"

"In this hundred square kilometers...... In other words, on 100 million square meters of land, 500,000 beavers have turned all the streams, rivers and lakes here from living water to stagnant ponds, and once the upstream rainfall is abundant, this 100 square kilometers will be flooded. Do the math, on average, a beaver plagues an area of 200 square meters. ”

"Oh, it turns out that Brother Gun was so scourged last night. ”

"I forgot that I had entered the beaver's area. Look at these little lakes, do you see these dikes? It's all made up of tree branches, which are the architects of nature, but they cause flooding. ”

Dayu said, it is better to block than to sparse, block rivers and lakes like this, and it is unreasonable to not flood.

"Brother Gun, are you going to attack them?"

"Isn't it illegal?"

"I'm not going to move them if they break the law. This year, the Argentine government ordered that local residents be encouraged to hunt beavers humanely, and the first plan was to kill 100,000 beavers. ”

Like the carp of the Great Lakes and the hairy crabs of the German rivers, these beavers are also dead by the biological introduction program.

"Don't think it's cruel to kill such cute-looking creatures, in fact, they're seriously damaging the ecology here, and if you see the parrots in the trees over there, they're gradually losing their habitat. The formation of a large number of lakes not only wiped out all the surrounding trees, but also brought a lot of flooding, and even caused strange changes in the weather, and the small animals that used to live here either moved or went extinct. ”

Just like the water hyacinth in Yunnan, it destroys the ecological environment of the lake after growing in a large area, causing a large number of organisms to extinct it.

Fang Hong raised his crutch, pulled out the wooden stick, and shot an arrow.

Nearby, a beaver lying on the dam basking in the sun could not dodge and was shot.

However, this is not a compound bow after all, and the arrow's strength is so weak that it can't kill it at all.

Fang Hong drew his axe, walked over, stepped on the branch, and slashed down.

"It's just time to make lunch, so don't watch the clip of peeling and cramping. ”

The stream was closed for a moment and turned back on.

"100,000 heads, the inhabitants of Tierra del Fuego live on the northeast and southern coasts, and there are only a few inhabitants here, and the killing speed is not as fast as the breeding of beavers. ”

"Biologists on Earth have always warned people to protect animals, but they have warned humans to be careful not to control the habitat of a living organism and not to spread. They are rodents. As the saying goes, rats bite elephants to death, and creatures like rabbits, rats, and beavers have super reproductive ability and are super destructive. If their spread is not controlled, it will only take a few hundred years for the earth to become a desert. ”

"Bragging, rats can destroy the earth?"

"There are 20 billion rabbits on the planet, and the number of rats is close to 200 billion, and if rats are taken to more places by humans, their populations will grow linearly. It only takes sixty-five years for a beaver to go from fifty to 500,000 here, and it only takes three months for a rabbit to mature, and it can renew three generations of offspring in a year, with an average of nine in each litter, and it takes less than three years to become 500,000 in a perfect state. As for the mice, they mature in three months and can give birth to nine litters in a year, and it only takes one and a half years to go from fifty to five hundred thousand. ”

", I hear me reminded of the bubonic plague ...... in the United States."

"There are two theories about the origin of rodents, one is the origin of ancient rats and the other is the origin of primates, and if the second is correct, then in fact, 55 million years ago, our ancestors were the same. Humans have always thought that the earth is their own, but in fact there are thousands of animals on the earth that are much more numerous than humans. ”
