06 07 11 - 06:457 billion humans.
Next stop, nine billion -- and after that, twelve. After that, 20 billion humans.
Even if we cram every one into a 650 sq ft apt, the resources they are going to need will be massive.
Food. Water. Roads. Hospitals. Schools. Malls. Workplaces. Factories. Sewage. Religion.
The concept of a planet covered in plastic, concrete and steel, where "animals" and "plants" are museum pieces, fast approaches. When we have total technological domination, there are no "bad areas." We just cover it all.
If we love life, we should be ready to cull.
As opposed to genocide, or eugenics, or even murder, culling is a process of saving people: identify the ones who should live. Assume everyone is dead, because we have taken a path of doom; however, pick the ones we should save, and either (a) focus on keeping them safe or (b) kill everyone else, guaranteeing the safety of the ones who should live.
My suggestion is simple -- we set up a merit/demerit system:
College education +1
IQ over 119 +2
IQ over 129 +3
Started own business +1
Military service +1
Violent crime -3
IQ under 109 -1
Drug addiction -1
Drives SUV -1
Add them all up: if over zero, keep.
Surely however there are more factors we should consider. Graduate education? Costco membership? Likes disco?
