Deep Sixed

In the deep sea, low oxygen levels, scarce sunlight, and freezing water limit the rate at which items decompose: Something that might survive a few years on land could exist for decades underwater. - ROVs photograph trash on the ocean floor.

0.0001 micromoles of oxygen per liter per year

If we look at how fast they metabolize, it would take them a thousand years just to reproduce themselves. They may be much older than this. There’s no way of knowing.

The Economist: The World in 2009

In 2009, a remarkably gifted politician, confronting a remarkably difficult set of challenges, will have to learn to say "No we can't", Guantánamo will prove a moral minefield, economic recovery will be invisible to the naked eye, governments must prepare for the day they stop financial guarantees, we will judge our commitment to sustainability, scientists should research the causes of religion, we will all be potential online paparazzi, English will have more words than any other language (but it's meaningless), Afghanistan will see a surge of Western (read: American) troops, Iran will continue its nuclear quest while diplomacy lies in shambles, the sea floor is the new frontier, we should rethink aging, (non-)voters will continue to thwart the European project -- but cheap travel will continue to buoy it -- though it has some unfinished business to attend to, and a Nordic defence bond will blossom.
