When I was a kid living along Massachusetts Bay, we often saw seaweed (various species of marine macroalgae – kelp, etc.) as somewhat irritating. It could get in the way of fishing lines, and it would pile up on beaches in rank rows.

But seaweed, which, blessedly, grows rapidly, is looking better and better. It absorbs carbon dioxide, absorption that directly fights global warming, and it offsets a bit of ocean acidification caused by carbon dioxide from our fossil-fuel burning; it slows coastal erosion by weakening the force of waves in storms that have worsened as sea levels rise, and provides shelter for innumerable marine creatures. It’s used to make food, fertilizer, medicines, bioplastics, biofuel and animal feed.

(I’m sure that many readers have tried the seaweed salad in ethnic Asian restaurants.)

And now researchers are investigating its use as a source of minerals, such as platinum and rhodium,  as well as “rare-earth” elements (which actually aren’t that rare), that are crucial in the renewable-energy sector and in other technological applications, too. Seaweed sucks up these minerals.

Much more research needs to be done to demonstrate all possible uses of seaweed, but the potential for seaweed aquaculture seems enormous. I can see many profitable new seaweed farms being developed off the southern New England coast. There’s already a large kelp-farming sector in the Gulf of Maine, benefiting from the size of available waters, and the industry is growing along the Rhode Island and Connecticut shoreline, too.

It’s heartening to see scientists working on all-natural ways to address global warming. Of course, in some places there will be fights over which sites to take over for seaweed farming; I hope that the broad public interest will usually win over, say, the demands of summer yachtsmen. Certainly, these farm sites should be chosen carefully, with guidance from the likes of the Marine Biological Laboratory, in the village of Woods Hole in Falmouth, Mass.
