I don't get it

The Interior Secretary is issuing new regulations, which carry the weight of law as long as they do not conflict with actual congressionally passed legislation, altering the requirement that federal agencies must assess the amount and effect of greenhouse emissions for construction projects.

The draft rules would bar federal agencies from assessing the emissions from projects that contribute to global warming and its effect on species and habitats . . . . [Interior Secretary Kempthorne said] "It is important to use our time and resources to protect the most vulnerable species. It is not possible to draw a link between greenhouse gas emissions and distant observations of impacts on species."

What you don't know can't hurt you, right? So we better know as little as possible. Nay, we MUST know as little as possible. Or the terrorist polar bears win.
