Can We Just Kill Off Invasive Species?

Author:

A Cane ToadInvasive species are plants or animals that are introduced to a new area where there are no natural predators to keep them under control. 

These plants and animals can grow to populations that are out of control and the results can range from annoying to life threatening. 

Most of these invasive species are introduced unknowingly by people traveling or on purpose by people that think they are fixing one problem, only to create many more. 

So why don't we just find all these invasive plants and animals and just kill them or introduce their predators to their new environment? The short answer is because it is hard and could cause worse problems. 

The long (and more interesting) answer can be found in this short, but informative, video by SciShow
