I feel that the main human problem in the future is the uncontrolled population, no more land for aquaculture, and even for economic equities, in this case implanted chips in human body are needed to control the movement and human populations, this sounds creepy, but this an effective way to become a Solution and future effectiveness. Bitcoin is the solution for the economy because natural resources for the production of paper money/metal coins are extinct, technology is the last human hope.
This is an unreasonable fear spread by some crazies, probably those weirdos from greenpeace. Do you know how much land is currently uninhabited? I'm not talking about land with extreme conditions like the Arctic Circle, but normal land that can be used for farming.
The answer is a lot, more than we need and more than we will need in another 100 years of growing. If somebody decided to grow food in the uninhabited parts of Russia, he'd be able to feed whole Europe for centuries to come. We're not facing overpopulation problems, just some areas are becoming crowded.
