Population Growth

Human population growth may be the largest threat to earth ecosystems. We develop land for living space, business operations, government use, transportation, waste disposal, recreation, agriculture, energy production, and mining. We are also depleting wildlife for food and profit. Population growth is probably not sustainable at the current rate.
