Seaweed: a future carbon sink?


Mmmm, seaweed. Not just good for keeping sushi from falling apart and smelling a bit funny on Britain’s beaches: it’s also apparently a future carbon sink.

The Associated Press says:

A group of scientists at a climate conference in Bali say they could also be a potent weapon against global warming, capable of sucking damaging carbon dioxide out of the atmosphere at rates comparable to the mightiest rain forests.
“The ocean’s role is neglected because we can’t see the vegetation,” said Chung Ik-kyo, a South Korean environmental scientist. “But under the sea, there is a lot of seaweed and sea grass that can take up carbon dioxide.”

One of the problems with seaweed as carbon sink is stopping the seaweed releasing carbon back into the atmosphere later on. Bad news for sushi and lava bread fans: eating it is not an option.

    OK. Here’s a radical idea…how about saving the planet by making less stuff. Oh, no. Hang on. There’s a problem with that. It doesn’t quite square with the capitalist system. We have to make more stuff else the system implodes. Maybe we should kid ourselves that we can manufacture our way out of this problem. But that reminds me of the old saying about fighting for peace is like f**king for virginity…is like manufacturing for a greener planet.
    We’re all doomed! Aaaargh!
