Daily Downers: Contaminations
>> Parks get contaminated by ammonium, which can subtly alter ecosystems. Yellowstone, Glacier, and Rocky Mountain National Parks, plus six other parks, have air that's increasingly contaminated with ammonium, possibly originating in concentrated animal feeding operations, says a report from the National Park Service.
>> Wal-Mart sold portable gas cans not compliant with Cali's clean-air regulations FOUR times in recent years, then settled for a mere $250K with the California Air Resources Board.
>> Radars taken out by global warming. "The Pentagon is closing down three of the 20 NORAD (North American Aerospace Defense Command) early-warning radar sites in northern Alaska because the ground they’re built on in some cases is literally crumbling into the Arctic Ocean as a result of erosion caused by waves on ice-free waters."
