Oil is the natural resource that allows access to all the other natural resources, so the curve for accessible natural resources can be matched to the oil exploitation curve. When oil production fluctuates, the curve for accessible natural resources also fluctuates. To find out the quantity of natural resources that is accessible per capita, all you have to do is superimpose the oil production curve and the population growth curve. Dividing the resources by the number of human gives the variation in per capita resources.
Although natural resource exploitation continues to rise (for the time being), per capita resources have been declining since the 1980s due to population growth.
Even as per capita resources are rising in some countries, e.g. China, other countries like Zimbabwe have none at all.
In 2050, per capita resources will have fallen back to 1950 levels, the population will have tripled, and natural resources also.
Better living conditions lead to increased production of nutritional resources, which results in a population increase. This in turn fosters knowledge, which improves accessibility to natural resources. By implication, exploiting and processing these resources increases the wealth produced, which in turn improves living conditions, and so on, in a closed cycle.
Economist graph data show natural resources as being in a constant state of upward flux. Unfortunately for economists, a large number of natural resources are exhaustible, and the Earth’s surface is finite. At some point, the cycle is broken and the population increase no longer boosts accessibility to the natural resources, because the per capita quantity decreases. Consequently, the wealth produced dwindles, living conditions deteriorate, the population declines, and the cycle reverses. The tricky part is the “moment of reversal”, when the population continues to increase as wealth begins to decline.
To sum it up, a decline in oil production will bring about a decline in accessibility to natural resources; exploitation will slow down and wealth will decline. Following a latent period, the population will start to decline in response. The upside of all this is that dwindling wealth will actually decrease pollution, allowing humans to breathe pure air and drink clean water.
