Mass extinctions occur when the conditions on Earth change faster than species can adapt. Since humans have greatly changed the conditions on Earth and continue to change them at rapid rates, a mass extinction is a likely possibility if nothing is done to reverse or stop the changes (mainly the amount of carbon dioxide being released to the atmosphere). Another common cause of mass extinctions are extraterrestrial which cannot be predicted and are somewhat spontaneous.
