The word "pestilent" is an accurate word to describe kudzu.
While kudzu may have its beneficiary moments, such as serving as cattle feed, its destructive cons outweigh its pros. Kudzu as we know is an invasive species. Why is that? It is because it grows extremely well, too well in fact. When a kudzu crown (basically the seed) is present, it will continue to grow. Even if there is a tiny piece of that kudzu crown left when you relocate soil or try to eradicate it, kudzu will continue to grow. Scientists also found that kudzu emits chemicals that form ground-level ozone, which is bad for the environment.
Overall, kudzu is an invasive species that destroys ecosystems and causes a ton of environmental issues.
