Acid rain is back, and thanks to farming, worse than ever

from The Grist. Factory farms not only spread disease such as swine flu, they are producing acid rain.
Policy makers, environmentalists -- even Republicans -- like to congratulate themselves on the "victory" over acid rain. As this American success story is usually told, acid rain's effects were addressed by a 1990 update to the Clean Air Act that created a cap-and-trade system focused on sulfur dioxide emissions from coal-fired power plants. Since the system was implemented, sulfur dioxide emissions dropped 70 percent, and threatened forests and wildlife were saved. Hurrah!

There's only one problem with that version of history: It's not true.
