Since 2021, China has repeatedly found incidents about the entry of alien species into China, such as: Shandong seized 38 poisonous ants, Xiamen seized 5 live Euphorbia longiflora, Jiangmen seized 3 live Hercules beetles, etc., which shows that there are more and more species entering China's territory, and in the case of more and more organisms entering, everyone is also very worried about the changes in the ecosystem, mainly because overseas species have entered, which will have an impact on China's ecology.
Since 2021, the most hotly discussed is the "red fire ant" invasive species, which has spread to 435 counties (cities, districts) in 12 provinces (districts and cities) in China, especially in the past 5 years, 191 new red fire ants have occurred in county-level administrative districts, which has doubled compared with 2016, so it is completely impossible to "control" the state, they destroy local organisms, and the threat to the local ecosystem is also very huge, so now it can be said that "everyone hates" red fire ants, but there is no way to remove them. However, this brings the news that an alien species has been intercepted.
The seizure of the "fire salamander" is the first (first) interception (first) interception (seizure) of live fire salamanders at the Beijing port, it can be said that it is very rare, it is intercepted in the inbound postal express box of live fire salamanders sent abroad, according to public data, the number of fire salamanders found this time is huge, a total of 19, which can be compared with our previous invasive species, and this time the fire salamander includes 9 female adults and 10 juveniles, some of which may also give birth to new juveniles.
So the harm is extremely great, the fire salamander was seized this time, once again issued a "warning" to us, the invasion of foreign organisms has become more and more common, since 2021, we have seen the seizure of foreign species is very much, so here also shows that the domestic "pet" tide is getting stronger and stronger, many people are willing to seek some very special species for breeding, completely do not consider the follow-up problems, most of what we have found now is also in the express mail.
And are all belonging to the "offshore" express, so a steady stream of foreign organisms appear, causing concern about the ecosystem is necessary, because not many people care about how much threat to humans may be brought to humans when they do not breed these organisms, when the incoming mail is seized, it is because the X-ray machine image is abnormal, so it is known that there are living organisms, if you avoid this pass, the real alien species have entered, but the specific place is from, not announced, so it is not clear, It just shows that it is "offshore", and it is certainly not local to China.
The fire salamander and other activities seized this time are one of the species prohibited in China, but the specific origin of the fire salamander intercepted this time is unknown, and the toxicity is unknown, but I can understand its general location from the data. In the world, there are about 500 species of salamanders, and the fire salamander is the most famous salamander in Europe, generally about 20 cm in size, with a black body, with yellow spots or stripes, and the creature mainly lives in mountainous areas.
The main food objects are a variety of insects, and occasionally eat small vertebrates, such as small frogs, so once they enter our country, small frogs may be threatened, and there are not many frog species in China today. At the same time, the fire salamander in Europe and the United States is a very common price is also a flat amphibian pet, so it is often used to breed, China found it this time, there must be someone to breed, otherwise it will not appear in our country,
The fire salamander itself has a strong reproductive ability and belongs to the oviparous birth, which is the terrible thing about the creature, it can lay 10 to 60 at a time, that is, 1 litter can produce 10 to 60, that is, 1 litter can produce up to 60, this yield can really be compared with mammals. No pig has the creature to produce, so it is very scary. And as long as the creature gives birth to the larvae, feeding ants crickets or fruit flies can grow rapidly, and after three months, it can eat ordinary small crickets, so it is very strong.
At this point, everyone should know why China wants to control the creature, because it has strong reproductive ability and is also very strong in preying on species such as scarce biological populations, such as small frogs, which will inevitably destroy the ecosystem, so it is very frightening, this is the situation of this organism.
China is one of the countries with the most biological invasions in the world, and more than 660 kinds of invasive alien species have been discovered, of which more than 50 of the 100 invasive species with the greatest threat in the world have invaded China. For example: water hyacinth, African giant snail, etc., these invasive species not only have an impact on water quality, but also have a huge impact on crops, these organisms in the field of large-scale spread, may lead to food production and so on.
That is the indirect impact on the survival of human beings, but also has a direct impact on human beings, for example, we say that the red fire ant, after being bitten, the serious situation may lead to human death, so this is a direct threat to human life, this is not still alarmist, many organisms have a fatal impact on humans, and many people who breed pets are mostly based on good looks, and will not care about its toxins, generally the better the species The stronger the toxin, the greater the impact on people and ecology.
Under normal circumstances, invasive species are rarely "cross-regional", but there are generally three invasion cases. Artificial introduction, trade unintentional introduction, natural introduction. For example, the alien species seized since 2021 are artificially introduced, fortunately all of them have been seized, otherwise after entering China, it is another catastrophic problem, so human activities are the key to the invasion of "alien species".
On the whole, we want to protect the ecosystem, in addition to protecting the local species, is to completely prohibit the entry of alien species, otherwise under the protection of decades, alien species in the absence of natural enemies, in a short period of time may be up to several decades of ecosystem destruction, so when we breed pets, it is best to breed local species, do not bring trouble to the protection of the ecosystem, this is not only a personal problem, but a problem for everyone living in their own country or region, One of your alien species introductions could bring about a greater catastrophe.
