The world is presently overpopulated by the billions. We obtained this surplus through sheer folly and shortsightedness, a.k.a “greed”. There is a valid reason why overpopulation of this magnitude never appeared in human history before. No other civilization before ours exploited the oil reserves that were tens of thousands of years in existence, predating all human life and converted them into agriculture and global transportation system.
But we did, and we built a overpopulated world that polluted, raped, destroyed it’s natural carrying capacity to such a degree that human life itself is now threatened. We became so accustomed to this temporary ‘abundance’ that we fooled ourselves into believing it would last forever. We were dead wrong.
