Here's crowdsourcing idea: "How do we prevent human extinction this century or the next?"

I have often dreamed of 8 billion people asking this question all at once and making up their answers and posting them online somewhere or just online everywhere at once.

What I learned in college the most was that the questions you ask in college and in life are the most important thing you ever learn in college.

People go there to learn all sorts of trades but this question is the real one people should be asking:

"HOW DOES THE HUMAN RACE NOT GO EXTINCT THIS CENTURY OR THE NEXT?"

If you can answer this question in a way that people can respond to it then maybe the human race won't have to go extinct during this century or the next one.

Also, if you have a good idea or a sequence of ideas that might save us from extinction then write about it so we can then have a chance to survive as human beings here on earth or on other planets too.
