Conclusion
Peak oil represents a grave threat to our food supply, in my opinion. Few are aware of how important the petroleum industry is to the agricultural revolution in which we live. This is why I am currently trying to buy a farm. Consider this, prior to the agricultural revolution, estimates of hunter-gatherer population sizes, based upon anthropological data show that humans were quite few in number.:
"Measures of world population size on the eve of the transition to agriculture, some 12 000 to 10 000 years ago, come from estimates of the maximum population density that this way of life could sustain. These generally range from 5 to 10 million people, and the highest figure--calculated on the assumption that the world was 'saturated' with hunter-gatherers --is only 15 million." (Landers, 1992, p. 402)
Agriculture based only upon animal energy allowed the human population to grow to about 750 million by 1750 (Cavali-Sforza, 1994, p. 68). Peak oil will do several bad things to the world's energy supply. It will force us to use coal, and if one uses coal to replace oil, because coal will be used at a faster rate, the US turns its 200 year supply of coal into a 44 year supply (assuming that there really is a 200 year supply to start with). This implies that by the end of this century, we will no longer have fossil fuels with which we can foster global warming. Nor will we have fossil fuels with which to run our tractors and we will return at the very least to the 1750s. Going back to an animal-energy based economy means that approximately 5/6ths of us must die. The post fossil fuel world, lacking some new energy source, will consist of not many more than 750 million souls. What an ugly century this will be. While there are some long-shot grasps-at-straws possible replacements for fossil fuels, the political turmoil resulting from mass starvation may preclude their development and implementation.
Sadly, JJ, your grammar school dropout neighbor is not alone.With all do respect...We aint even begun to tap the earths resources. You cant apply math if the information keeps changin...I believe this way of life can end but its not because we have somehow EXHAUSTED the earth of its resources. Thats just not true. We have only tapped a minute portion of the earth resources and many of them replenish themselves and are only now out of our reach or some environmental bullshit keeps us from goin to get it. There is enough oil in the Gulf of Mexico for generations after generations to consume...These scientists plug in what they think they know and some computer model makes guesses. We will run out of food but it aint because the earth is overpopulated or tapped out !. Its because power comes from control of food and water !! People will die off because of evil power hungry assholes not the depleation of resources...

Potable water and living oceans are just environmental bullshit.

Your response would appear to accept the idea that we have reached "peak oil." Your charts would only be relative to this conversation if you did. Is this true? If peak oil is still in the future, as I thought you had argued, then the charts are meaningless.
