In recent years, the number of invasion of foreign species in my country has shown an upward trend, becoming one of the countries with the worst harm of foreign species invasion in the world. According to the "2020 China Ecological Environmental Statistics": my country has found more than 660 species of invasion. Among them, 71 types have caused or have potential threats to the natural ecosystem and have been included in the "List of Chinese Foreign Invasion Species", and 219 kinds of invasion of national nature reserves.

Some foreign invasion species are harmful because they reproduce rapidly, and the number has increased geometric levels. Due to the lack of natural enemies, it is often wanting to grow as a new dominant species in the local area. Causes severe biological pollution and cause irreversible damage to the ecosystem.

Water hyacinth

The water gourd was native to South America. At the beginning of the 20th century, it was introduced into my country as an ornamental plant. It was promoted as a pig feed. Because of its large reproduction, it was often covered with the entire rivers and lakes. , Destroy the ecological balance in the water.

"One yellow flower in Canada"

"Canadian Yellow Flower" is an ornamental plant introduced from North America in Shanghai and other places in Shanghai and other places in the 1930s. Later, Yiyi has a strong ability to reproduce and quickly occupy space. Essence

Brazilian turtle

Brazilian turtles, also known as red -eared turtles, are produced in Brazil and are produced in the United States. Brazilian turtles are the world's recognized ecological killer. Many countries such as China have listed it as dangerous foreign invasion species.

Red fire ant

Red fire ants are harmful creatures in agriculture, forestry and entering plant quarantine in my country, and are also one of the hundreds of the most most dangerous invasive species in the world. Red fire ants can directly consume the seeds, fruits, young buds, etc., which leads to the reduction of crops, which will also affect the growth and reproduction of some animals. At the same time, the red fire ant injury incident also occurred from time to time.

Fushou snail

Fushou snails, also known as the big bottle snail and Apple snail, are native to the Amazon River Basin, South America. In the early 1980s, it was introduced to China as a edible snail. Because of its strong adaptability and rapid reproduction, it became a huge harm.

Grassland greedy moth

Grassland greedy night moth larvae (top) and adults. Grassland greedy moth is a relocation pest of the global warning of the United Nations Food and Agriculture Organization. It has the characteristics of "special energy", "special energy" and "special energy flying". It has strong reproduction capabilities, fast relocation and spread, and seriously harm the growth of crops such as corn. In 2019, grassland greedy night moth invaded my country for the first time.

Pine width

Pine materials are native to North America. Pine material nematode disease is a devastating disease caused by pine trees that are parasitic in pine trees and mainly spread the medium in the pine body. After 40 days of infection of pine trees, it died. This disease has a wide range of spreads, fast spread, and difficult to prevent control. It is called the "AIDS" of pine trees.

Gulin trees are under immune injections of pinemark width disease.

Hollow lotus seed grass

The hollow lotus seeds are produced in Brazil, also known as water peanuts and grable lotus seeds. They were introduced into China in the 1930s. They were extremely harmful species and were listed as the first batch of foreign invasive species in China.

Coconut

Coconut heart leaf armor is a major hazardous creature with major danger. It is native to Indonesia and Papua New Guinea and is now widely distributed in the Pacific Islands and Southeast Asia. Coconut heart leaf armor has the characteristics of rapid reproduction, strong destruction and prevention.

食 食 鲳 鲳

In July 2012, Zhang Kaibo, a citizen of Liuzhou, was attacked by three fierce fish when he bathed the puppy in the Liujiang River section, and his palm was bleeding and bleeding. After the fish was caught, it was formally confirmed by the expert group to formally confirm that the fish was a Sang's Sawli native to South America. It was a kind of food and a fierce carnivorous animal.

In response to foreign invasion of species, my country's management system is constantly improving. The "Administrative Measures for Foreign Invasion" will be implemented on August 1, 2022. The measures are clear that the Ministry of Agricultural and Rural Affairs, together with relevant departments, establish a census system for foreign invasion species, organize a national census every ten years; establish a motion system for foreign invasion species, build a national foreign invasion monitoring network; establish a system of information release system for foreign invasion species.

The resolution of this problem must also rely on social and individual efforts to prevent foreign species invasion, and everyone is responsible. The Biological Safety Law of the People's Republic of China stipulates that any unit or individual shall not introduce, release or discard foreign species without authorization. Don't think that the invasion of foreign species has nothing to do with yourself.

At the same time as Ruzhou's arrest of crocodile sparrows caused a lot of attention, Shanghai Customs announced on August 25 that Shanghai Pudong International Airport Customs seized 300 living ants in a batch of pseudo -reporting as "Lego toys". These ants are identified as brutal harvest ants. The barbaric harvested ants were originally produced in Europe, fierce temperament, and habit of eating and collecting plant seeds. In recent years, the domestic ant pet circle has been hot, and many people have tried to mail ants from overseas to enter the country.

Affected by factors such as hunting mentality, alternative pets represented by rat, snake, lizard, crawler, etc. have been sought after by many people in recent years. In order to pursue trendy stimuli, some people blindly raised wild animals and plants, and even at the expense of foreign creatures without "Haitao". This behavior not only lacks awe of nature, but also lacks awe of the law. Essence

The apprenticeship is not enough. Consolidating the country's "biological safety defense line" must not only improve the legal system of biological safety and further improve the cost of illegal costs, but also the public must also build a overall national security outlook and protect you and me.
