The regulatory and legal system that for the last 50 years has protected the environment in the United States--the air that we breathe, the water we drink, the food we eat, and the toxic chemicals we encounter--is facing an assault unlike anything since the modern environmental movement began in the 1960s. The New York Times in the past year has committed an extraordinary amount of resources not just to investigate the controversies inside the headquarters of the Environmental Protection Agency. But we also have fanned out across the United States to document the real impact this radical shift in regulatory policy is having, via an ambitious investigative project that demanded all of the skills journalism can deliver from FOIAs, to databases, to litigation, to government sources, narrative storytelling and innovative online and print presentations. It is one of the biggest stories of our times. And no one has covered it as aggressively as The New York Times.
