With world food prices projected to continue rising, so too will the number of hungry people.
We know from studying earlier civilizations such as the Sumerians, Mayans, and many others, that more often than not it was food shortages that led to their demise. It now appears that food may be the weak link in our early twenty-first century civilization as well.
Will we follow in the footsteps of the Sumerians and the Mayans or can we change course–and do it before time runs out? Can we move onto an economic path that is environmentally sustainable? We think we can. That is what Plan B 4.0 is about.
Mobilizing to Save Civilization
Plan B aims to stabilize climate, stabilize population, eradicate poverty, and restore the economy’s natural support systems. It prescribes a worldwide cut in net carbon emissions of 80 percent by 2020, thus keeping atmospheric CO2 concentrations from exceeding 400 parts per million.
