New Smog Rules

Hosted by

The Environmental Protection Agency proposed new smog rules today. The stricter standards target smog-producing factories and power plants by limiting how much ozone they can pump into the air. Ozone is the emission that causes smog. Smog, in turn, causes all kinds of health problems: asthma, heart disease, even premature death. And it just so happens that California is the capital of smog in America.
