Preventing disastrous offshore spills may require space-program diligence

As crude oil continues to spew from the Gulf of Mexico seafloor — two weeks now after the Deepwater Horizon accident and sinking — questions continue to surface about what went wrong. To my mind, what went wrong was almost blind optimism on the part of industry, regulators, the states and the public. And any niggling doubt about the wisdom of that optimism was likely assuaged by at least a little greed.

Rural ozone can be fed by feed (as in silage)

Livestock operations take a lot of flak for polluting. Researchers are now linking ozone to livestock, at least in one of the nation's most agriculturally intense centers. And here the pollution source is not what comes out the back end of an animal but what’s destined to go in the front.
