A foreign company plans to clear several dozen acres of ecologically valuable mangrove swamp in Vietnam for the creation of a shrimp aquaculture facility.  This decision will create economic profits of $5000/year to the company (which hires substantial numbers of local villagers) after one year of construction but will cost $10,000 (paid upfront) to build.  In addition, the loss of the mangrove habitat will reduce spawning and nursery habitat for valuable fish species - thus reducing the catch of fish by artisanal fishermen from 1000 tons to 750 tons per year (which has a market value, after costs, of $10/ton).  Assume that these losses are experienced from the very first (construction) year onward and are permanent.
