Goldman Sachs and the World Bank foresee global GDP expanding massively over the next 35-years. Whereas today, America's economic GDP is the world's largest at over $16-trillion, by 2050 China's GDP will have soared to over $52-trillion, dwarfing America's then $34-trillion. Canada's GDP will drop from 11th place to 16th.
What's not addressed in these projections is where mankind will find the energy and other natural resources to support this enhanced economic activity. We're already using the Earth's renewables at half again the natural replenishment rate. To increase the global economy fourfold in 35-years is more than exponential growth. What must the boys at Goldman see in store for 2100?
