Kudzu, a Japanese vine introduced to the southeastern United States, has become an invasive species and covers millions of acres. While it was initially planted to control soil loss, Kudzu out-competes native species and harms the ecosystem.
Step-by-step explanation:
Kudzu, a Japanese vine introduced intentionally to the southeastern United States, has become an invasive pest species that covers over 7 million acres in the region. While there are no direct pros to Kudzu in native environments, it was originally planted in the 1870s to help control soil loss. However, due to its rapid growth, Kudzu out-competes native species and takes over their niches, causing harm to the ecosystem.
