Garrett Hardin
b. 4-21-1915; NYC
d. 9-14-2003; Santa Barbara, CA (suicide - Right to Die)

Ecologist Garrett Hardin is best know for his essay, The Tradegy of the Commons.

Hardin asked his readers to picture a pasture open to all and to expect that each herdsman will try to keep as many cattle as possible on the common pasture. He goes on to tell us that this model may work satisfactorily for centuries because diseases and wars keep the numbers below the carrying capacity of the land. However, when social stability becomes a reality, the commons fails because each herdsman seeks to maximize their personal profit by keeping just one more animal on the pasture - the population grows, the pasture remains a finite resource.
