UK's lost sea meadows to be resurrected in climate fight

First seagrass restoration in Britain will capture carbon rapidly and offer habitat for lost marine life

"We think this whole bay was once carpeted with seagrass," says Evie Furness, waving across the sparkling, sunlit waters of Dale Bay in Pembrokeshire, Wales.

The underwater meadow is long gone though, a victim of past pollution and shipping. So from a boat half a mile from shore, Furness is feeding a long rope into the water, which carries a little hessian bag of seagrass seeds every metre. "We've passed the 800,000 seed mark now," she says.
