What's the situation? As China's ecosystem changes, so does the news of invasive alien species. And according to the "List of Invasive Alien Species in China", China has found more than 600 species of alien species, which has a very large impact on China's ecosystem, and many species groups have entered China's "nature reserves", so the restoration of local biological populations has brought great difficulties, and now China is also increasing the control of alien species.
Since 2021, there have been many exotic species seized in China, and there are also species that have spread, the most typical is the "red fire ant", and the biggest response to the interception of alien species is "Dalian Customs intercepted 100 live rat women", "live beetles" and so on. This all shows that the entry of alien species into Our country has become a "general trend", here can only be said to be hard customs personnel, as long as there is an alien species to enter, it may bring great impact.
The main sources of alien species are two cases - natural introduction and artificial introduction. Human factors account for most of it, and it is actually customs interception, that is, mail, so it may be the rise of the "pet tide". And with the rise of the "pet tide", many people are also seeking resources in this regard, hoping that they can be unique breeding. But they did not think of the impact after the introduction, did not think of what impact may be brought about after breeding, which really needs to be popularized.
<h1 class="pgc-h-arrow-right" data-track="18" more than 7,000 kilometers of parcels entered China > and were intercepted by customs</h1>
According to the Shanghai Customs, the package intercepted this time is more than 7,000 kilometers away from China overseas parcels, and among the two packages intercepted, 239 "ten thousand tooth monsters" were found, which were tested by the Customs Center, which were two exotic species - forest onion snails and covered large snails, both of which are strictly controlled to enter China, and once they enter China, they will inevitably have a great impact.
And in these snails, there are more than 26,000 teeth, many people when buying, completely do not notice these problems, but also pamper them, breed them, as pets. Indeed, in terms of appearance, it is also "stupid and cute", so it is deeply loved by everyone.
But what we need to explain here is that it is an alien species, if you buy it and are found, it will inevitably be seriously dealt with, but this time who is receiving it, there is no explanation for the time being. So even if the "pet tide" rises, everyone buys and sells freely. However, it is enough to breed native organisms stipulated by science, so that there will be no impact, do not breed exotic species, and make a little contribution to the maintenance of the environment.
<h1 class="pgc-h-arrow-right" data-track="17" >what species of forest onion snails and covered snails, and how harmful is it? </h1>
Forest onion snails – Forest onion snails don't look much different from our regular species, but this species is not native to China, and is mainly distributed in Central Europe, northern Europe and the United States. Shanghai is not the first time that forest snails have been intercepted. On another occasion this year, 154 live forest snails were found in the so-called "toy" package, which also aroused heated discussion. From here, it can also be seen that forest onion snails are indeed more popular in China, and they are not afraid of violations and similar incidents.
How harmful are forest snails? Non-native species are harmful, and forest onion snails are mainly more influential on our crops, they will directly destroy a variety of vegetables, melons, fruits, flowers, and huge amount of food, so as long as the forest onion snail breeding area, can quickly eat vegetables, melons and fruits and so on. At the same time, they can also achieve a new generation of reproduction through vegetables, melons and fruits and other agricultural products, so remind everyone not to buy.
Cover big snail - cover big snail is more powerful, hear "big snail" is definitely very large, indeed it belongs to the large snail species, this creature is not distributed in China, mainly distributed in Western Europe and Eastern Europe parts of the country. The species is also very edible, and can ingest food equivalent to about 5% of its own body weight at a time, and the target is also mainly crops, initially feeding on the young leaves of humus and fresh plants, but when it grows up, it begins to eat the stems, leaves and fruits of grapes, lettuce, rape and other plants.
Therefore, it is also dominated by edible crops, according to the encyclopedia data, there are 5 to 6 snail layers, the shell height is 38 to 45 mm, the shell width is 45 to 50 mm, so it does belong to the giant snail, which is the basic situation of the two organisms.
Obviously, forest onion snails, cover large snails are not native to China's organisms, and the damage to crops is extremely large, so as long as it appears we must eradicate it, can not let it spread in our country, it is not easy for china to carry out ecological environmental protection, we do not like to breed pets, and hurt our ecosystem. In recent years, China's protection of the ecological environment can be said to have cost a lot, and it is difficult to maintain, if because of your personal problems, and bring about huge environmental changes, you are really a "sinner".
<h1 class="pgc-h-arrow-right" data-track="14" > summary</h1>
With the change of China's ecological environment, it has indeed become better and better, China's forest coverage rate has reached 23.04%, forest stock has reached 17.56 billion cubic meters, grassland comprehensive vegetation coverage has reached 56.1%, wetland protection rate has reached 52%, and 150 million mu of desertified land has been treated. Under such a good ecological environment, if everyone does not take good care of the environment and introduce exotic species, it is really a "failure", and our decades of efforts may be in vain.
Don't underestimate the alien species, just like the well-known red fire ant, China's 12 provinces, 435 counties and municipalities have its footprints, if someone is bitten by the red fire ant, it may even bring fatal effects. Therefore, do not underestimate the alien species, their destructive strength and harm to the environment are "unimaginable".
