1- Suppose world carbon emissions are expressed as the following product:

Carbon emissions = (energy/person) X (carbon/energy) X (population)

If per capita energy demand increases at 1.5 percent per year, fossil fuel emissions of carbon per unit of energy increase at 1 percent per year, and world population grows at 1.5 percent per year,

(a) How long would it take before we are emitting carbon at twice the current rate? (b) At that point, by what fraction would per capita energy demand have increased? (c) At that point, by what fraction would total energy demand have increased
