Mr. Chris wanted you to catch this video. It is about invasive species! Invasive species are plants and animals from other places in the world that are brought here to Maryland. Some are harmless enough, but others are dangerous to both the flora (plants) and fauna (animals) here in Maryland because they have no natural predators and they compete with native (flora and fauna from Maryland) for habitat and resources (like food and water).
