How can a farmer and a cornfield in the midwest affect the fishermen in the Gulf of Mexico? In this video segment adapted from the independent film Big River: A King Corn Companion, the filmmakers explain how agricultural runoff from the Midwest has... contributed to a massive "dead zone" in the Gulf of Mexico. A cornfield treated with conventional chemical fertilizer promises a bumper crop, but chemical runoff from the farm enters the Iowa River, eventually draining into the Mississippi River and the Gulf of Mexico. In the Gulf, these dissolved nutrients allow algae to flourish. The algae's decay depletes the water of oxygen, creating a dead zone where shrimp and fish are starved of oxygen and die. Closed captioning included. Run time 02:41.

Architect Kate Orff sees the oyster as an agent of urban change. Bundled into beds and sunk into city rivers, oysters slurp up pollution and make legendarily dirty waters clean -- thus driving even more innovation in "oyster-tecture." Orff shares her... vision for an urban landscape that links nature and humanity for mutual benefit. Kate Orff asks us to rethink “landscape”—to use urban greenspaces and blue spaces in fresh ways to mediate between humankind and nature. (10:00)

Protected patches of land are the only spaces some creatures have left to explore, find food, and make their homes -- away from all the angry traffic. But mucky rubbish flows all over the place when people put pollution into streams and rivers.
Pl...astic,
metal, styrofoam and other manufactured materials clog up our water
ways. So if you chuck stuff in the street you can expect to have to
drink it later on. Ewww!
Our living planet, and our earthling
family are more precious than anything man-made. Why should companies
make money by selling you stuff that destroys your own enviornment?
Don't buy it! And if you see a special spot in distress, have a think on
how you can help. In some cases you can ask the council to clean up
junk -- but it could take ages, and why should they have all the fun!?
The
mud might be squelchy and the rubbish is gross but it can be a great
adventure to go out of the road to help out -- and maybe meet a shiny
eel or mossy tortoise - realizing just how closely we are all connected

These photographs of albatross chicks were made in September 2009 on
Midway Atoll, a tiny stretch of sand and coral near the middle of the
North Pacific. The nesting babies are fed bellies-full of plastic by
their parents, who soar out over the... vast polluted ocean collecting what
looks to them like food to bring back to their young. On this diet of
human trash, every year tens of thousands of albatross chicks die on
Midway from starvation, toxicity, and choking.
To document this
phenomenon as faithfully as possible, not a single piece of plastic in
any of these photographs was moved, placed, manipulated, arranged, or
altered in any way. These images depict the actual stomach contents of
baby birds in one of the world's most remote marine sanctuaries, more
than 2000 miles from the nearest continent.
