The below shows possible futures. These, however, invariably spark strong reactions and questions that must be answered.
The outer graph shows the development over a period of 2 million years. The smaller graph in the blue frame shows the development since the beginnings of agriculture, some 240 generations ago. Humans with our potential and posture have existed since at least 100,000 years, which is 4,000 generations of 25 years each. Modern time with our explosion of populations and resource consumption started around 1750, that is 10 generations ago. Present world population size is 6.5 billion (2006) - and growing at a rate of 80 million a year. Compare facing the future with on-line population counters. Resource consumption and depletion is growing relatively faster than population growth because of economic growth.
The open question is which key resource will be depleted first and will then lead to a collapse of the present structures. A grim future lies ahead. Unless we decide to halt growth and convert back to a low resource use society. We will count ourselves lucky if full-scale resource wars can be avoided.
The below graph shows the development - past and possible future - from 1900 to 2100.
The utimate scenario could well be - but God forbid! - the flooding scenes as pictured here ... albeit not limited to the blacks or colored people. We believe climate change will also hit the white-collared whites.
The above graphs and perspectives raise important questions, which must be answered. You find some important questions here.

The Limits to growth curve was never really falsified. Only the time frame was incorrect. Today, more than 40 years later, the situation is worse since we have grown our economies and the world population and per capita resource consumption enormously. |
The 1972 curves from the Limit to Growth can be transposed along the time axis and we see the same threatening future of depletion and ensueing die-off.
One should not believe that existing and yet-to-be-invented technology will save us. Since technology cannot revive extinct species, nor can it recreate depleted resources.

When deaths get higher than births, the birth rates cannot continue to rise, as is suggested at the point "x" by 2050.
When the population declines rapidly, the birth rates must decline as well. Because less women cannot increase individual births to compensate for the reduced number of women.
