It is all about the human population exponential growth numbers versus Department of Energy's known world wide hydrocarbon reserves. When you graph the horizontal asymptote for natural human carrying capacity of the planet with the horizontal asymptote of the artificial carrying capacity provided by hydrocarbons, then we see asymptotic collapse between 2025 and 2070. In this case, asymptotic collapse means a minimum die off of all peoples above the natural carrying capacity. The natural carrying capacity is likely below 1 billion people if you eliminate mechanization for farm equipment and high yield crop production from hydrocarbon related fertilizers. However, it is more realistic to expect the die off closer to the 2025 mark than the 2070 point.

If teleportation technology is not developed soon and allow humans to colonize other planets, then the die off will happen.
