Juroara, I partially agree with you.

I agree that the world can support a large human population. Not so sure about the "rich people telling the world we need less people" part.

Russia, for example, has a huge untapped areas that could be used for agriculture. Also, Africa could also support itself with today's genetically engineered crops, but apparently when the United States sent over a bunch, they were denied because the government thought the crops would be "unhealthy".
