Ecologist Garrett Hardin developed “lifeboat ethics” as a metaphor for examining the problem of unfettered population growth (Hardin, Psychology Today 8:38–43, 1974). Imagine a lifeboat in the ocean with 50 people aboard and room for only 10 more. The lifeboat is surrounded by 100 swimmers. Hardin pondered the question: when should swimmers in distress be taken aboard and how many should be offered salvation, given the capacity constraints of the lifeboat.
