Last week I posted a comparison of food prices a hundred years ago in America compared to food prices today - not in terms of the dollars they paid then, but in terms of how long an average worker of that time had to work to earn them. Food today costs us much less in time and work than food did then. I wonder if you were surprised.
Since the world has a fixed amount of resources and a rising number of people consuming them, those resources are running out, right? Back in the 1970-80's that was a hot topic.
Paul Ehrlich published his book, The Population Bomb, in 1970 saying on the first page that hundreds of millions of people were going to starve to death in the '70's because the earth could not support so many people, and that population growth was a cancer. Today the earth supports almost 8 billion people, twice as many as at that time, and food is more (not less) available. Why was he so wrong?
