Crab Claws, Sustainability, and Your Money

Perhaps the most sustainable crop in the world is the stone crab claw, a seasonal Florida delicacy. You see, stone crabs are caught in live traps, a claw is removed, and the crab is returned to the water. The claw regenerates, usually growing back larger than before—an ability they evolved to escape predators, which now supplies Florida fisheries with a sustainable catch.

We have come a long way since 1883, when a keynote speaker at the International Fisheries Exposition in London proclaimed that “all the great sea fisheries are inexhaustible.” We later learned to our chagrin that it is, in fact, entirely possible to harvest anything to the point of extinction.

Fortunately we also figured out how to nurture fisheries to produce more fish, and to limit harvest to sustainable levels. You can take out the entire population of fish just once…but you may be able to harvest some fraction of the population, year after year, until the end of time.

A pertinent comparison may be made to your stock of wealth in retirement. Like a fishery, a portfolio can be over-harvested until it inevitably declines and disappears. But with sustainable management, it may produce a recurring crop. This is the endowment principle in action. A dollar may be spent one time only—but if invested, the income from it may be spent every year, in perpetuity.

Decades ago, our life expectancies did not extend long past retirement age. Planning for a short retirement, one could aim at a target sum and figure that it would be spent down over a few years, then there would be a funeral. But with many life expectancies extending decades past retirement, the arithmetic of planning has changed completely. Not every financial planner has kept up with the change.

Sustainable fisheries assure the world that it will not run out of fish. Sustainable portfolios reduce the chance that you will run out of money in retirement. One of our objects is to help you understand what part of your resources may be considered permanent capital, to be invested on a sustainable basis.
