lead you to believe otherwise. There are literally THREE ways humans could be become extinct.

a. a new predator emerges that takes ppl out
b. extinction level event
c. all people stop having babies


the changes of a & c happening are rare. now certain populations could become extinct (and have). but as a whole, the world? no. but did you even read the article which spoke on the issues OTHERS bought up in this very thread about overpopulation and the real issues in regards to this decrease in population growth?

But why would extinction ever be a concern of yours? it's going to happen one day but outside of option A or B, not in our lifetime...so really, you should focus on things that affect our generation, and our children's generation because really that's all we have.
