It is clear that healthy ecosystems provide the underpinnings for the long-term health of economics and societies.

There are fewer chemical pollutants in the air. Our drinking water is safer. Our food standards have been raised. We’ve cleaned up more toxic waste sites in three years than the previous administrations did in twelve. The environment is cleaner, and we have fought off the most vigorous assault on environmental protection since we began to protect the environment in 1970. We are moving in the right direction to the 21st century.

They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
