Why EPA proposal to put high-polluting diesel trucks back on American roadways is a bad move

The U.S. Environmental Protection Agency (EPA) is once again in the spotlight, this time by its proposing to allow high-polluting diesel “glider” trucks to operate on America’s roads.

Home breathing environment: Recirculated air

Going the distance: As to pollution’s ‘hitching a ride’ on locomotive air, implications

Air pollution isn’t motionless – it moves. And, currents of air (wind), is what enables its movement. The occurrence can alternatively be called air pollution locomotion, the word “locomotion” meaning place-to-place moving. Depending on conditions present, pollution in the air can travel thousands of miles from where it is sourced. There is conclusive evidence that … Read more
