Republicans regained control of the U.S. House of Representatives in 2010 at a time of unprecedented global challenge and change. Instead of devoting the next year to embracing opportunity amid turmoil, though, the lawmakers waged the worst legislative assault in history against the commonsense safeguards we all depend on to protect our environment and health. In a single calendar year, the Republican-led House voted nearly 200 times to weaken, block, or delay needed measures that defend our air, water, wildlife, and lands. This book tells the story of that misguided campaign, how it put our nation at risk, and where we need to go from here, for the sake of Americans everywhere, for the sake of our children's future.
