More than 660 invasive alien species have been found in China, how did they invade?

These alien species may have been brought into the country by smuggling, some mailed as ornamental fish, and some naturally invased.

I know that my country's laws do not allow these alien species to enter the country, but some people prefer to bring these species into the country. It may be because these alien species have high profits, because they are more profitable, so these people like to take risks, and some people secretly bring these alien species into the country. Because of the rapid growth rate of these alien species, the number of native species has become less and less, and the native species have been invaded by alien species, which has also affected the local ecological balance.

The alien species we know, such as the alligator gar, this fish is an invasive species, this fish is poisonous, but many people like to introduce it as an ornamental fish, many people keep the alligator gar in a fish tank, and then this fish grows up, and many people release this fish. Because this strange fish is particularly strong in surviving, it causes all other fish to be eaten by it, destroying the local ecological balance. Alligator gar is usually entered by mail, the growth rate of alligator gar is particularly fast, alligator gar does not pick the environment, does not pick the water quality, it is because of the artificial introduction of alien species, so it leads to more and more alligator gar, and even a lot of injuries have occurred.

A lot of alien species have been found in our country, and these alien species are brought in artificially, and some people secretly put alien species in some mailed packages, trying to get through the customs in confusion. There are some alien species that are naturally invaded, such as some insects, which fly directly into our country from abroad and have a very great impact on our environment. Because some alien species are naturally invaded, they have led to pests and diseases in our country, which has affected crops and trees.

Every year, there will be a lot of alien species invasion, these alien species are natural invasions, so it is impossible to prevent them, if these natural invasion insects are found, they must be harmless in time.

Most of them are brought in by people or products that enter the country, and because many species are very small and difficult to catch or detect, they are brought into the country, and they will grow unbridled without natural predators!

Invasive alien species are mainly introduced into China through intentional and unintentional means, deliberately introduced by humans mainly for ornamental and other purposes, and unintentionally these species are mixed with goods to enter China.

China is one of the countries most seriously affected by the invasion of alien species, according to reports, invasive alien species are divided into natural diffusion, unintentional introduction and intentional introduction.

Introduction: The natural ecological environment of each region has a complete biological chain, and the invasion of alien species is likely to lead to the disconnection of the original perfect biological chain. If the biological chain is broken, the ecological damage is very serious, China has now found more than 660 kinds of alien species, these alien species have a very large impact on our ecological environment.

3. Don't release animals at willThe reason why there are so many invasive alien species is that on the one hand, they are intentionally introduced, and on the other hand, some people deliberately release them. Some people buy some alien species in the pet market, and then release these species in Xinjiang, this random release has caused damage to the ecosystem, and there is also a way to send species from abroad by mail, which are not allowed.

It will destroy the local ecological circulation system, and it will also affect other local animals, it will also damage the environment, and it will also damage crops and affect the normal life of human beings.

After the invasion of alien species, there will generally be a phenomenon of rapid mass reproduction without natural enemies, and in serious cases, it will destroy the local natural ecological environment and affect the survival of local acoustic species. Sometimes it will affect the interests of farmers and lead to economic losses.

Alien species can destroy the local ecosphere, and once the ecological balance is destroyed, huge natural disasters can occur.

This kind of foreign invasion is very strong in attack power, and has a certain degree of toxicity, which is easy to threaten people's lives.

The danger of invasive alien species is that because they are alien creatures, we do not know their natural enemies, so there is no way to check and balance, which causes them to reproduce very quickly.
