1. The popular "king" wild boar.
First of all, I would like to introduce you to a new face who "unexpectedly became popular": wild boar. Wild boars, as the name suggests, are pigs that live directly in the "wild" without being raised by humans. The emergence of "wild boar" is not the product of a "native species", but an "invasive species".
It is said that wild boars were able to cross the ocean to North America, and it was a group of "brave explorers" who "contributed a lot". In fact, because "it is difficult for a good woman to cook without rice", they can only eat this bite of "American" flatbread "in another way".
Speaking of these explorers, these explorers are really "creative": in the 30s of the 20th century, these "pig brothers" were "brought into the jungle with one hand and released back to North America" by the "thrill-seeking" Americans: half to make the "hunting of wild boars" more "challenging", and the other half to advance the "hunting season".
Seeing that there are more and more "pig brothers" rushing into North America, "hunting tourism" has also become a "fashion", but these "explorers" did not think of their "unintentional moves", which have already made "wild boars' reproductive ability unstoppable".
In fact, in less than 10 years, there have been a number of "wild boar breeding bases" in North America, large and small, a family of three "pigs with women" life, in the "unique" ecological environment, wild boars "can not be idle for a moment", trying to "expand the family".
The end result: within a few decades, the "boar's face" has taken up a huge area in North America. As a result, the Americans can only publicize a "hunting tour" to "prepare for the large-scale clean-up of wild boars", but these "wild acts of unknowing the height of the sky" can only make wild boars "more rampant challenge" to humans.
2. The "God of Sewers" Asian carp.
After introducing the "arrogant and unreasonable" wild boar, now we will reveal a "kung fu" general: Asian carp. The Asian carp is a type of fish that is "almost indistinguishable" in terms of appearance, and the most common examples are "grass carp", "silver carp" and "bighead carp...... It can be said that as long as they appear in "the rivers, lakes and ponds of North America", then "it must be an Asian feast".
This incident began in the 70s of the last century: when the United States was a country with "extremely high biodiversity," there were some "terrible" problems, that is, the "disorderly spread" of organisms, which led to the "extermination" of North American species by some "Asian invaders."
In the face of this life and the years of life, the Americans chose a "fearless" "confrontation method": they decided to start sorting out the "invasive species" "from home", so they let the "Asian carp" "enter the land of North America".
Then it can be shown that the Americans "came prepared" and instead of "blocking the Asian geese" from entering the "American market," they also "vigorously encouraged" the people to "raise fish" at home, and the "Asian carp" quickly occupied the "rivers" and "waters" of North America.
But "the situation is about to change": American researchers have discovered that "Asian carp" can both "devour unstoppable" and "elusive", and if they appear in "the waters of North America", the "peaceful countryside" will become "in dire straits".
Under these circumstances, the Americans decided to make a big move: not only did they clean up the entire waters, but they also specially purchased "professional equipment for fish hunting", and also "hired a professional team" to sort out the "Asian carp", but "the waist bag could not support the soldiers", and soon "the number of Asian carp in general will still be small."
But in fact, the Americans' method of "turning the spring breeze into rain" is only "resisting the Asian carp" and thinking that it is "large-scale breeding...... In less than 10 years, these "Asian warriors" were able to take their place in the "moist soil" of "North American life".
It is worth mentioning that before entering the 21st century, the fighting form of Asian carp has undergone "earth-shaking" changes: they are no longer "stubborn", but have become "badger-like sturdy", not only "athletic", but also "deceitful" "height" (1.2 meters) and "weight".
Although the Asian carp "give what they want" on the "North American continent", the "scientific and technological spirit is still very good", and they not only "attack" "from the physical level", but also "break through" by "chemical means", and these "battles" will continue for many years, and they are still "peaceful coexistence" to this day.
3. The gorgeous Asian tiger prawns.
The next species to be introduced to you is the "biggest headache for Americans" water crab: the Asian tiger prawn. The Asian tiger prawn, as the name suggests, is a "shrimp species that lives in Asia" in China, and "it is worth mentioning that this creature also "thrives and reproduces" in the "waters of North America".
In fact, it is precisely because "they have a strong ability to adapt" and "crazy reproductive ability" that they will thrive like the United States and the West Entertainment Lake. But it all happened "suddenly".
You know, it is obviously a kind of "shrimp", and "Asian tiger prawns" can also be as "thick" as human "wrists", which shows that when they "live" and "hunt" in the "waters", they are extremely "wonderful" existence, not only that, but they can also "avoid risks" and "check in one fell swoop" at the most critical moment.
So these "kings of the water" can "stand out" in the waters of "North America", but it also means that they are "determined" to "infringe on other aquatic organisms" in the local area. In fact, not only in the midst of the "Great Rebellion", but they were also able to "easily" infest other creatures in the waters of North America, so it is "reasonable" that these "Asian tiger prawns" are not "spurned" by the locals.
In order to reproduce "better", they will even migrate "to the waters downstream", and this behavior happens to "affect their" lives. But soon the "good news" came: the "hatred" of the "North Americans" for the "Asian tiger prawns" did not stop, and they continued to "persist in numbers for several years".
Even though the Americans spent "several years" cleaning up these "Asian tiger prawns", the strong "vitality" it showed was "jaw-dropping", so the war ended in a "peaceful negotiation" way. It can be said that this Asian tiger shrimp war is a "win-win" ending, although "there are still countless Asian tiger shrimp" in the "waters of North America", but at the same time, their own numbers have not increased much. ”
4. "Mysterious species": Kudzu.
The next thing for you to introduce is the "ordinary people" who "don't know the truth", in daily life, we must have seen these "kudzu", but never thought that in "North America" they can become "troubles", they are "down-to-earth" just to "feed themselves", but unfortunately, the waters and water environment of "North America" do not allow them to live "as they like".
So what happened? As a "mysterious plant," when Americans "first see" their "lovely faces," they will unconsciously "exclaim" and "see how beautiful these plants are, and how sophisticated the Chinese people are."
However, if "if you see kudzu again, Americans will "look solemn": "If you see these plants, you must follow in my footsteps", "If you accidentally step on kudzu, there will be a large group of kudzu roots, which will affect life in the United States."
Although Kudzu is not a "household name", its "population strength" is also able to "adapt to any environment...... Most kudzu live in a "mild" environment, but when "threatened to their survival", they will look for a new environment to "adapt to life" "at night".
Not only that, in the process of "population" biased towards "breeding", they also have the "fighting spirit" of "showing superbness...... For example, "one kudzu" can expand to "dozens of kudzu" in just a few months, so that their "population" expands rapidly.
5. "Trout figure": snakehead fish.
The last invasive species to introduce to you is the "snakehead fish". This "weird" but "fascinating" species can "live alone" for 6 years on the "continental United States", and then live a life of "reproduction", and the environment of "partial activity" is "different", and it can "reproduce".
However, it is precisely because of its "reproductive ability" that the "snakehead" will "disintegrate" the "population" of the "snakehead" in the "river environment", and the "living environment of the North American mackerel" will be degraded.
In response to the "lawlessness" of the "snakehead fish", the American people have also "introduced several years of clean-up measures", that is, "introducing some "native fish" that have a "suppressive effect" on the "snakehead fish", but soon these "methods" will also make people "disappointed".
