Dolphins have fascinated humans for millennia, giving rise to an abundance of stories and myths about them, yet the actual details of their lives in the sea have remained elusive. In this enthralling book, Kathleen M. Dudzinski and Toni Frohoff take us into the dolphins' aquatic world to witness firsthand how they live their lives, communicate, and interact with one another and with other species, including people.

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.

More than 12,000 years ago, in one of the greatest triumphs of prehistory, humans colonized North America, a continent that was then truly a new world. Just when and how they did so has been one of the most perplexing and controversial questions in archaeology.

Science magazine describes the Pascagoula River of southeast Mississippi as the last unaltered large river system in the lower 48 states and southern Canada. Along its banks and watershed, 600,000 acres of public lands - wildlife management areas, national forest, wilderness areas, national wildlife refuges, Nature Conservancy preserves - ensure the creation of a tremendous natural river system.
