Massive vines that blanket the southern United States, climbing high as they uproot trees and swallow buildings. A ravenous snake that is capable of devouring an alligator. Rabbit populations that eat themselves into starvation. These aren’t horror movie concepts – they’re real stories. But how could such situations exist in nature? Jennifer Klos gives the facts on invasive species.
