Aquaponics combines plant cultivation and fish farming: Fruits and vegetables are grown in water reservoirs that also house fish. The fish waste fertilizes the plants, and they, in turn, clean and filter the water. 

This symbiosis is an ideal example of the type of closed-loop, waste-free sustainability championed by green advocates: There are virtually no unusable byproducts, and there’s little you need to add to the system to keep it going.

Train in Alabama oil spill was carrying 2.7 million gallons of crude - latimes.comhttp://www.latimes.com/nation/nationnow/la-na-nn-train-crash-alabama-oil-20131109,0,780637.story#axzz2kRpnIcPu

A train that derailed and exploded in rural Alabama was hauling 2.7 million gallons of crude oil, according to officials.

The 90-car train was crossing a timber trestle above a wetland near Aliceville late Thursday night when approximately 25 rail cars and two locomotives derailed, spilling crude oil into the surrounding wetlands and igniting a fire that was still burning Saturday.

Each of the 90 cars was carrying 30,000 gallons of oil, said Bill Jasper, president of the rail company Genesee & Wyoming at a press briefing Friday night. It’s unclear, though, how much oil was spilled because some of the cars have yet to be removed from the marsh.
