7. Biting insects and blood-borne pathogens, begone! But with some kind of “don’t screw up the entire food web/population balance” rider.
8. There’s got to be some kind of population reduction. I know this is going to be why the peasants rise up and burn me in my palatial roundhouse, but I think there are too many people. Finding new ways to grow more food seems like a losing proposition, eventually, what with our planet being finite and all. Best suggestion so far: Everyone is reversibly sterilized at birth, no exceptions. Then, after you turn 21, if you want kids, you apply for a breeding license. At first I don’t think there will even be any more hoops than that. You apply for one, you get one. Like a fishing license.
