As recently as 11,000 years ago - "near time" to geologists - mammoths, mastodons, gomphotheres, ground sloths, giant armadillos, native camels and horses, the dire wolf, and many other large mammals roamed North America. In what has become one of science's greatest riddles, these large animals vanished in North and South America around the time humans arrived at the end of the last great ice age.

No other species in Earth's history has been able to disregard the natural laws that govern population size quite like humans have. But population growth has come with an increase in resource consumption, which has created a number of environmental problems: Farmland is being degraded, fresh water is becoming polluted, fish are being overharvested, forests are being flattened, fossil fuel emissions are driving global warming, and the list goes on.
