This graph shows world population growth throughout history. The data comes from the United Nations. I like to pay attention to the part of the graph that shows humanity just muddling along for tens of thousands of years. I like to contrast the short, brutal, filthy lives those humans undoubtedly led with the lives of obese, whiny Americans.
Human beings the world over owe their lives to technology or, more specifically, to the men responsible for discovering it was possible. Most people, as this graph so amply demonstrates, would not be alive in any time but the last few hundred years. Most of us would not even have been born.
