How often in today's environmental debates have you read that "the science is in dispute"—even when there is overwhelming consensus among scientists? Too often, the voice of science is diminished or diluted for the sake of politics, and the public is misled. Now, the most authoritative voice in U.S. science, Science magazine, brings you current scientific knowledge on today's most pressing environmental challenges, from population growth to climate change to biodiversity loss. Science Magazine's State of the Planet 2006--2007 is a unique contribution that brings together leading environmental scientists and researchers to give readers a comprehensive yet accessible overview of current issues.
