Shouldn't there be a safety on this or something?

The next mad extinction won't be for another 100000 years, wait till then.

The "next" mass extinction is right now.
https://en.m.wikipedia.org/wiki/Holocene_extinction

The next "proper" mass extinction where a dominant life form goes extinct like at the end of the Cretaceous or the granddaddy of them all, the Permian Mass Extinction

That's not how they are defined.
Besides, we've already lost *ALL* of the North American megafauna... did you even click that link?

No I did not.

You should. It shows that the Sixth Mass Extinction Event is well underway and it's looking mighty grim. At an estimated 140,000 species lost every year, this is the worst since the K-Pg you mentioned.

Nice pun
