Another person obsessed with the "number" of people on the planet, and missing the point.
There are enough resources, and enough space, to provide for the seven billion people on the planet. No amount of resources are sufficient for populations that refuse to live as humans.
The current problems are mostly caused by a "reverse Darwinism" being enforced by the self-anointed global elites -- the "survival of the un-fittest". We have about 1.6 billion muslims on the planet, subscribing to an ideology that preaches only chaos, death, and destruction. These creatures, from populations with average IQs below 85, operate at the level of baboons who, because they are too stupid to do anything constructive, insanely rip each other apart, along with any other creatures that happen to be in their vicinity.
The elitists keep feeding and providing for the inner-city sub-humans, promoting and encouraging lifestyles of dependency and degeneracy. Without all the freebies, these people could learn to read, write, work, and could become productive, functional humans.
Nothing but wasted human potential. It isn't the number of people that is the problem. It is the percentage of that number who will never become fully human.
