This TED-Ed lesson highlights three examples of how invasive species can destroy entire ecosystems. In one case, the introduction of the Burmese python led to a rapid decline of an already sensitive species in Florida. In Australia, European rabbits eat themselves out of house and home, and an Asian plant called kudzu wreaks havoc in the South. All of these species and several others were introduced to foreign areas by humans with unintended consequences.
When a species is introduced into a place where none of its natural controls exist, its population can grow unchecked to the point where it becomes a pest. It begins to out-compete native species and possibly drive them to extinction. These invaders also have an effect on the economy by destroying crops and wood products.
Once established, these invasive species are difficult to eradicate, so it’s best to keep them out in the first place. See the seven worst invasive species on the planet, and take action to keep them out of the biologically sensitive Sonoran Sky Islands in the Southwestern United States.Whizzco
