Despite their prediction for the most likely path of post-peak fuel production, the authors of the letter, Kai M. A. Chan and Hadi Dowlatabadi of the Institute for Resources, Environment & Sustainability at the University of British Columbia, hold out some hope:

"Peak oil" represents not a crisis but a cross-roads. One path leads to energy production methods that are more environmentally destructive, but easier because of our existing infrastructure. The other realizes the promise of renewable alternatives and smart growth. When focused, environmental advocacy has been successful in helping society choose the right path. To do so here, we must recognize that "peak oil" brings both threats and opportunities, and will not alone define the right path. We're still living with a six-century fossil fuels legacy prompted by "peak wood" in the UK; it is time to make sure the path chosen now is more sustainable, socially and environmentally.
