Sounds perfectly reasonable....you can just pretend that 160 million more ****** won't exist in 2100 because you won't be around to care.
Imagine how much more wonderful places like Haiti, The Central African Republic and India would be if we could only increase their population A BILLION PERCENT......

I mean all we would have to do is to run a bunch of 100 mile diameter sewer lines from all those places down to Antartica, [using nuclear powered pumping apparatus to get the outgoing sewage from point A to point Z] and then use more nuclear powered apparatus that is stationed in Antartica to convert the 1 gazillion gallon per minute flow of incoming sewage to perfectly potable water and highly nutritional fluid that will be delivered by nuclear powered pipelines back to those 80 trillion people....!
