Draw the demand curve for an environmental service, for example carbon sequestration (process of capture and long-term storage of atmospheric carbon-dioxide) from tree planting and discuss what its slope means as a measure of willingness to pay for the service (explain the direction of slope). Label the axes on your graphs clearly.
