Why should they be unsustainable? Lots of people do not have the energy (ie. heat in Western Europe, for example), food, goods and transportation options they desire. And we certainly can have 10x the current energy usage on earth without destroying the planet. Just because we haven't historically doesn't mean it can't be done, or that we won't (in fact we will, since we will run out of fossil fuels a lot sooner than we'll run out of people). It will take some technological advancement, and finding something else for the middle east and Russia to do, but surely we can do better than reducing the human population? I feel like taking a "just outlaw it" approach is definitely going to make many people suffer, and it's not necessary. We should discuss other options, and research them.
