Economist Dr. James Wong argues that economic growth cannot continue indefinitely on a finite planet—limits to growth are physical realities, not pessimistic assumptions.
Which ecological analysis would best support Wong's limits argument?
Resources are finite
Current economic activity requires 1.7 Earths of resources annually; efficiency gains are outpaced by growth; and critical systems (fisheries, topsoil, aquifers) are depleting at unsustainable rates with no substitutes
Growth has slowed in some countries
Economists debate growth
Correct Answer: B
Choice B is the best answer. Overshoot (1.7 Earths) + efficiency insufficient + irreplaceable depletion proves physical limits.
💡 Strategy: Physical limit arguments need quantified overshoot and inability to substitute.
