Question

The biomass of the forest increases at an annual rate of 3.0 * 10^5 kg/ha.
The forest biomass is 50% carbon by mass.
Each year the district uses 4.0 * 10^5 gallons of fuel oil for heating and hot water.
10kg of CO2 is produced when 1 gallon of fuel is burned.
1.0 kg of CO2 contains 0.3 kg of carbon.
The cost of putting 1 ha of the forest into conservancy is $10,000.
