Professor Wang Zhenghuan, School of Life Sciences of East China Normal University, said in an interview with Xinmin Evening News that the Nurcun was native to South America and was a rodent animal. Nowadays, many countries around the world have farming, with high fur, meat and medicinal value. Occasionally escape will naturally breed in the appropriate environment. The hazards of the Nurf are mainly the dykes caused by digging holes, eating crops and vegetation, and destroying crops and greening. If the density is very low, it will not pose a threat to the security of the local ecosystem. But as foreign species, they should not appear in our open environment, regardless of whether they can cause species invasion.

Wang Zhenghuan emphasized that with the improvement of people's living standards, more and more foreign animals (pets, fur, meat, meat, and medicinal) will be increasing, and strengthening source management is the key. As an individual, we must have a sense of environmental protection. Whether it is foreign species or local species, it must not abandon the suburbs at will.
