Blog #5: Are Humans Impacting the 6th Extinction Event?

Throughout Earth's history, there have been five major extinction events. Because of those events, many species either became endangered or extinct. But all of those events occurred due to a certain cause. There lately has been talk that humans may cause the next extinction event with pollution and such. I think it is completely possible that it could cause a major extinction event in the distant future with the effects of pollution. But that's not the only possibility, I think that another could also be caused by natural events such as major ocean level changes and asteroid impacts.
