Drugs are like Judaism was to Nazi Germany. Hitler killed a greater proportion of the gypsy population than the Jewish population even though he killed more Jews than gypsies. He really destroyed the community a lot more and you never hear about that. You do but not nearly as much. If Hitler hadn't killed so many people horribly in concentration camps and battlefields then there'd be an even bigger population problem today.
War keeps down the population so to speak.
Then again, World War II was a triumph of American style capitalism. I don't think the real problem is population. Yeah, distribution of resources. I just drove through France. France is all agricultural and it's beautiful and no one lives there, basically.
