Biological invasion (distribution, hazards, prevention and control measures)

Biological invasion mainly refers to the entry of organisms that are not native to the environment into the environment. Biological invasion actually has good and bad aspects. For example, we introduce a species to maintain the ecological balance of the environment. For example, the dung beetle was introduced to Australia and solved the problem in Australia. The problem of large amounts of animal waste in animal husbandry and the natural environment is also caused by the introduction of organisms that replace the food chain function of another organism in the environment. What I mentioned above may not be called biological invasion in some respects, but let me mention it. Of course, there are many organisms that invade a new environment, which will cause great damage to the environment, because after these organisms enter, they have no natural enemies and have abundant food, leading to large-scale reproduction. It will eventually destroy the entire ecological balance and may lead to the extinction of native species. Searching the Internet will bring up many examples. I will not copy and paste. As for prevention, the first step is to cut off the source and control various planting and breeding to prevent the introduction of harmful species. Eradication is a long process that consumes huge human and financial resources, so it is best to nip it in the bud. I hope it will be helpful to you.
