Preface: If you are not afraid of Gatling, you are afraid of biological invasion, and this drama is not exaggerated when it is placed on the old beauty who has been "tortured".
Biological invasion
An Asian carp directly "drained" the ecosystem of the Great Lakes. Just when it was in trouble, the arrival of Asian tiger shrimp directly made it give up its struggle.
Call it destruction, I just want to lie flat!
What kind of "heavenly ability" does this tiger shrimp have, so that the old beauty who has always been fierce is helpless?
What is the horror of biological invasion?
1. Asian tiger shrimp
Tiger prawn fishing
I'd rather face a tiger with real ammunition than face this basket of smelly shrimp! An American netizen complained so much on social platforms, and his "rich voice" also resonated with the broad masses of the American masses.
One after another, they threatened: "When you fight a tiger, take me one!" ”
These jokes are enough to prove the "scariness" of tiger shrimp. Tiger shrimp, also known as grass shrimp, is a very common meat shrimp in Asia.
Tiger prawns
The firmness of the meat, coupled with its large amount of protein and trace elements, is loved by Asian people.
American businessmen apparently saw a huge business opportunity in them, so in 1988 they imported a large number of tiger prawns in Thailand at a high price.
At this time, they were immersed in the dream of making a lot of money from anti-sale, completely unaware that their actions would bring incalculable losses to their country.
Tiger prawns
As seasoned businessmen, they know the disasters that come with biological invasions. To prevent it from flooding again like Asian carp, they have set aside a special area for farming, which is a farm in South Carolina in the United States.
Under the "special treatment" of Lao Mei, tiger prawns have made their home in this small sea. It has to be said that this sea area is indeed like a paradise for tiger prawns.
There are no natural enemies, and the environment is suitable for survival.
Tiger prawns
Therefore, the size of tiger prawns is larger than in Asia, which really makes Laomei make a fortune.
To think that on it, it is indeed profitable. Therefore, many water plant farmers have also joined in. But just when he was intoxicated with the sweet dream of shrimp for money, the arrival of a natural disaster completely pushed the situation into an uncontrollable range.
In 1988, an unprecedented hurricane swept through the Atlantic Ocean with lightning speed. The hurricane set off huge waves that overwhelmed the breeding base.
Hurricanes are coming
These foreign tiger prawns, "ride" on the ocean current, come to various waters of the United States. Although the relevant departments carried out fishing and rescue operations in the first place after the incident, unfortunately, less than 300 of the more than 2,000 "outsiders" were recovered.
At this time, there was only one thought in everyone's mind: "It's over!" In fact, this is not because he is too timid, but because he has a living example in front of him, which has to be a headache.
After 30 years of fear, tiger prawns, which could only be obtained by order, were completely flooded.
Overflowing tiger prawns
A female shrimp can lay 50-1 million eggs, even if how to deduct the loss in the process of adult shrimp, the survival rate of tiger shrimp is a practical problem that cannot be underestimated.
At first, fishermen could only catch them in specific waters, but over time, the sphere of influence of tiger shrimp has expanded.
In any ditch, you can find its figure.
The waters are comfortable, there are no natural enemies, and the United States is paradise for them! However, for Americans, there is a bitter hatred between them and tiger prawns!
Second, unimaginable economic losses
Dollar
The continuous growth and expansion of tiger prawns has continuously squeezed the living environment of their native aquatic organisms, resulting in a large number of native aquatic organisms "on the verge of extinction." ”
In addition, tiger shrimp continues to expand, and its size is also soaring rapidly, gradually endangering the daily life of local residents.
In various waters, ecosystems have been irreparably hit by this alien species. What's even more frightening is that the power of these shrimp is not only in aquatic creatures and humans.
As omnivorous, they do not refuse to come, constantly eating the roots of mangroves.
mangrove
And as we all know, the United States is often threatened by waves. As a coastal guard, Mangrove has been working diligently to prevent soil erosion.
However, whether it is to increase fishing efforts or to intervene biologically, the end result is not ideal. Although tiger prawns themselves have a lot of nutrients, they can bring a lot of energy to the human body.
But in any case, the Americans did not like it.
Helpless Americans
One is the psychological effect, as "white people", they did not disdain to eat these alien creatures at first. The second is the change in the meat quality of tiger shrimp due to different growth environments.
When in Asia, the body is small and the meat is delicious. But one side of the soil and water to raise one shrimp, the species after arriving in the United States, its own meat quality has become a little more woody.
Although it is constantly expanding, its own meat texture is greatly reduced.
In addition, most of the local likes in the United States are "eaten raw", which is called the freshest taste of preserved food. And the fishy smell of tiger prawns eaten raw is also an unacceptable existence.
Tiger prawns
An even more important reason is the flooding of tiger prawns in U.S. ditches. The water quality problem has also led to an increase in harmful substances in the body of tiger prawns.
If consumed for a long time, it will cause huge losses to human functions. This is good, you can't catch it, you can't sell it.
Lao Mei really shot herself in the foot this time, but what room for redemption is there to regret that this matter has become a foregone conclusion?
It can be said that the United States has a long way to go to resist the invasion of alien creatures!
Carp invasion
In fact, the United States seems to have been fighting alien invasion in recent years.
Carp, which is popular on the mainland, was introduced from Laomei to Japan, and it was completely spread and multiplied.
Initially, it was introduced to clean up the flooded seaweed organisms in the United States, and the number of fish in the sea was declining due to overfishing.
So think twice, the United States paid a lot of money to bring back the Asian carp species.
However, "it is easy to ask the gods and send the gods", and the arrival of the carp quickly cleaned up the algae that was flooded at that time.
Overflowing carp
However, in the later stages of development, the carp population gradually crushed the local native fish species. Not only that, because the number of reproductions is too fast, and the growth is rapid.
The density of carp in the river area seriously endangers the navigation of ships, and there have even been incidents of carp attacking people.
The so-called attack was also caused by carp attacks that crossed the surface of the water while the boat was sailing normally.
As a result, the hull was unstable, causing the ship to capsize. In response to this series of "special attacks", the relevant US governments have also organized special fishing teams.
Professional fishing teams
But how can human power compare to the rapid reproduction of fish? Before the catch is sold, a new wave of carp is active again above the surface.
In addition to fishing, Laomei also called on the domestic people to eat carp. But unexpectedly, carp, which was well received in the mainland, became a disgusted existence in the United States.
The fundamental reason is that the carp itself contains too many spines, which is a very difficult fact for American housewives.
Overflowing carp
Perhaps forced by the carp, Lao Mei actually used rotenone toxin. However, handfuls of toxins were thrown into the water, and the carp was not much less, but the local fish were irreparably damaged.
This series of useless operations is also completely put in order. Helpless, they could only cry in front of tons of carp.
In addition to the fish and shrimp invasion suffered by the United States, Australia is also facing the suffering of biological invasion.
Third, Australia driven crazy by rabbits
Rabbit invasion
"Australians would never like rabbits!"
Can you believe it? Australia, where there are now 10 billion rabbits, was not even a rabbit in its native land, not even a single rabbit hair.
And now all the "arrogant" rabbits are all outsiders, and this is all "thankful" to a man named Thomas Austin.
At that time, just out of the novelty of hunting, he secretly imported several hares from Europe.
Hunting rabbits
But before the interest in hunting was enjoyed, the land around his house was ravaged by rabbits.
In 1926, according to incomplete statistics, there were 10 billion rabbits in Australia. Even the authorities have joked: "Australia has been ruled by rabbits!" ”
In order to solve these culprits who make a mess of the land, the government is racking its brains. From rabbit hunting competitions to bringing in foxes for biological intervention, it didn't help.
More and more rabbits are born, and they have become the most troubled existence in the local area.
rabbit
They flock in groups, constantly impressing, and nibbling on local herbs. The little rabbits, who eat an amazing amount of food, sweep the lawn away.
But as we all know, Australia is proud of its livestock industry. However, the pasture is gone, and what kind of economy is this developing.
Unable to bear it, they attacked again.
Bunny slogan
Even in order to eliminate them, the Australian government directly piloted helicopters and bombers to indiscriminately bomb the rabbit's "main base". And in the shells that were thrown, a large number of viruses that can kill the cells of the rabbit's body were also added.
But unfortunately, the rabbit's vitality is completely beyond their imagination.
Even to this day, the "war" of Australians with rabbits has not stopped.
Perhaps some friends will be curious, will the above creatures invade the continent? From a practical point of view, their chances of invasion are small.
Plague rabbits
Not to mention that the mainland was the first country to farm carp, just talking about the "108" practices, mainland carp is unlikely to flood.
When it comes to Australia's "enemy" rabbit, I believe that without saying much, everyone will think of a joke: "No rabbit can leave the Sichuan-Chongqing region alive." ”
The Sichuan people's love for rabbits will never allow them to become a disaster. I think if it weren't for the fertility of the rabbit itself, it would have been eaten as a "rare animal" by us!
Finally, let's talk about tiger prawns, not to mention the thickness of the arms, which have not yet grown into a slap or not, it has become a delicacy on the table.
Tiger prawns served to the table
It can be said that it is the Chinese "foodie attribute" that prevents the above biological invasion phenomenon. ”
But to say that there are no biological invasions on the mainland is actually wrong.
According to official statistics, the mainland has become one of the most biologically invasive countries, with as many as 660 invasive species.
The annual loss of these alien organisms to the mainland is as high as 200 billion yuan, in addition to economic losses, their continuous erosion of the space of native animals and plants, but also caused a decrease in biological nature.
Biodiversity
Reducing the harm caused by the control of these organisms is not only the responsibility of the relevant departments, but also each of us.
Fourth, the author believes
First of all, biological invasions include plant invasions in addition to animals. And these foreign invasions are often attached to the luggage of returning tourists outside their borders.
One is the unintentionality of tourists, and the second is deliberate smuggling.
Customs inquiries
But in any case, their behavior has brought great losses to the local production environment. This also requires extra careful inspection by customs officers to try to avoid the invasion of these species.
It can be said that biological invasion is not only about the United States, Australia, and China. It is closely related to every country on this planet, because the losses it causes are irreversible existences.
And what we ordinary people can do in advance is not to buy or release alien species without authorization, thereby causing trouble for the country.
