It will probably lead to mass production of unhealthy foods and a lot of sickness.

I'm not sure when, but when the times comes and they is too many humans for resources i would love to be watching from above or wherever you go a purge style ending.

But i hope the human race never ends

As someone else said before i take it your watching Utopia,Good Program.
But beside it being a TV Show if you look into the story and out it all together some of it does line up in hard clear evidence, People think we will find something or they would never do that, The thing is the government is already doing it, In my opinion the world has already started this faze of change, Starting with the NSA, Who knows what is to come next.
My advice is be prepared for the worse because i may get laughed at now but when we are being rounded up you will wish you never laughed.

I'm not too worried about it. I would probably be dead by the point the world becomes far too crowded. If it does, I expect people to adapt like we've done so forever now. And I bet we'll start taking up land in deserts and other such places.

That would only reduce the population so little, it wouldnt matter, anyway that would never happen everyone would complain lol
