There is nothing more fundamental to human health than breathing clean air.

But now, after four decades of bipartisan action to ensure we have safe and health air, the Clean Air Act is under attack.

Senator John Barrasso (R-WY) has introduced a bill that would permanently block the EPA and every other federal agency from using the Clean Air Act -- or any other environmental law -- to do anything about reducing America's climate pollution.

This is part of a broad, coordinated pro-polluter legislative assault to weaken America's clean air standards and block climate action.

You can help stop this assault on clean air before it starts.

Join the Environmental Defense Action Fund's campaign to Clear the Air and demand Congress reject the "Do Absolutely Nothing on Climate" Barrasso bill -- and all other similar legislative assaults.
