The great successes of the modern environmental movement in the '60s and '70s had laid the seeds of their failure in the early years of the 21st Century. They had built institutions filled with lawyers and scientists well suited to lobby policy makers who basically shared their world view. This worked well when liberals controlled the Congress and much of the federal bureaucracy, and when the politics of the time were more supportive of active government efforts to regulate the economy and clean up the environment.
