Invasive species are harmful not because of what they are, but where they happen to be. In this lesson, Jennifer Klos will explain the threat that invasive species pose to our natural ecosystem. An example of invasive specie is the Kudzu vine, also known as ‘the plant that ate the south’.
When it was introduced in the south-eastern United States for porch decoration and cattle feed, it multiplied quickly due to the availability of sunny fields, mild climate, and no predators. Although sometimes non-native species are introduced by some natural phenomena (such as storms and ocean currents), mostly this introduction occurs due to human activities. On the bright side, now many governments are closely monitoring the transport of plants and animals across borders.
