99 percent of the species that have ever lived on this planet are extinct. The best way to understand when another extinction could happen is to study the previous five mass extinctions. The video discusses each one, the cause, the impact, and the numbers of species killed. Then it predicts the next mass extinction. (Hint: We are living it right now.)
