Invasive organisms are foreign organisms that are not native to the local area. To put it simply, it is the organisms that entered afterward adapted to the local life, and then reproduced in large quantities. Their invasion breaks the original ecological balance of the local area, damages the local biodiversity and brings fatal disaster to the ecosystem!

These exotic species all have similar characteristics: "no natural enemies, strong reproduction, and high adaptability"!

According to the 2019 Bulletin of China's Ecological and Environmental Conditions released by the Ministry of Ecology and Environment, a staggering number of more than 660 alien invasive species have been found throughout China.

To be honest, the current case is also "eat" is the most perfect solution, those who spend a lot of manpower and financial resources abroad, but also just do not cure the root cause, if there is a leakage of fish, exotic species comeback is just a matter of time!

On the issue of biological invasions, many countries have encountered, the following through a few typical cases to deeply introduce the harm caused by biological invasions.

On the origin of the crayfish, some say it escaped from the U.S. freighter, and some say it was intentionally dropped by Japan as a biological weapon. Before the invention of the spicy crawfish in China, few people in the world dared to eat the creature because of its tenacity and its scavenging.

Thanks to the Chinese people's "iron teeth", the invasive species of crayfish ended up being eaten one at a time, and two at a time. Spicy, thirteen spice, garlic, take turns on the battlefield.


The snail is very harmful to agriculture, it will eat rice seedlings, affecting the rice harvest; coupled with the lack of local natural predators, the snail rampage, becoming a major species of farmers abhorred.

In short, the danger of biological invasions should not be underestimated.

The spread of exotic species is also diversified, in addition to the natural way, human initiative to carry is also a very important reason, some people are hunting, in order to keep pets, while some people are in order to eat and sell, however, no matter what the purpose of the income before it is best to understand the habits, and do not arbitrarily discard some of the unknown attributes of the creatures, such as Brazilian turtles we know, once the "release" of the turtle. The "release", will bring great damage to the local environment, do not do something you think is a "good deed" thing.
