1. At present, the invasion of alien species in China is very serious, which will bring serious ecological problems.
Invasive species will break the local ecological balance and destroy the local ecological environment. Invasive species are likely to get out of human control and cause serious damage, because there are no competing organisms in the environment. If they spread, the consequences will be unimaginable and will endanger the survival of local endangered species. China has always been a country invaded by exotic species, such as crayfish. We can make it into food, but other exotic species are not so delicious, which will bring local economic losses.
2. The invasive alien species in China are very serious, and the prevention of invasive species should be dealt with at the source.
We must cut off the way for alien invasive species. If a foreign tourist brings a creature, we must consult the information to ensure that the creature is not so aggressive, and don't let the creature escape and come into contact with other creatures. And put an end to the release of wild animals in different places, especially the illegal trade of wild animals. If wild animals are released at will, it will cause the danger of biological invasion. When we encounter alien invasive species, we should report to the relevant departments for artificial elimination.
In a word, the problem of alien species invasion in China still deserves our attention. China has become one of the countries suffering the most from alien invasive species. Hundreds of alien invasive species have been identified, which cause serious economic losses every year and will also affect the agricultural development in China. Species are interdependent and mutually restrictive, but the introduction of exotic species will upset this balance and cause serious problems.
