The ecological footprint of the average U.S. citizen is significantly larger than the global average. What would happen if all humans on Earth each had an ecological footprint that matched that of a typical American? A.The need for ecological services would decrease. B.The global population would surpass fifteen billion people. OcThe global usage of resources would become much less sustainable. O.The balance of the three Es would shift more to economy.

If all humans on Earth each had an ecological footprint that matched that of a typical American, the most likely outcome would be:<br /><br />C. The global usage of resources would become much less sustainable.<br /><br />This is because the ecological footprint of the average U.S. citizen is significantly larger than the global average, meaning it requires more resources and generates more waste. If everyone on Earth lived this way, the demand for natural resources would far exceed what the planet can sustainably provide, leading to environmental degradation and resource depletion.
