What is Kudzu?

Tens of thousands of people actually visit Antarctica each year. Who knew? I did not realize this. Personally, I have no desire to go there at all, so when I heard this report on TV, I was very surprised. What surprised me even more was the fact that the area's native ecology is being threatened by invasive, nonindigenous species. WHAT? The fact is, that all these visitors accidently carry an average of about 10 plant seeds each, from wherever they came from, often attached to their boots or bags. So now, populations of alien plant species have already been discovered in the Western Antarctic Peninsula. This migration of alien species is causing native species to die off and will eventually threaten the entire area, according to this report. Again. Who knew? It reminds me of another plant, Kudzu, that was introduced in this country because of its fast growing abilities and it was used after road construction to plant and grow quickly on bare ground near the highways to prevent erosion. This plant though, has proved to be a curse, smothering native plants and trees. You can see it everywhere, hanging from the trees and bushes all up and down the Interstate network of highways. Humans just don't seem to realize that these things can inadvertently threaten the natural ecology and cause more harm than good. Scientists are just now realizing the threat to Antarctica, but it is already TOO LATE to reverse the growth. What do you think?
