The Daily Mirror reports never mind agriculture – algae-culture is the future as seaweed farms spring up along the British coastline. The slimy brown stuff is among the most eco-friendly raw materials as it does not need fresh water, land or fertilisers. Considered a superfood, kelp is also one of the most versatile and fast-growing organisms on the planet. Growing at up to two feet per day, it also feeds fish and other creatures, while capturing carbon emissions in the same as trees and helping to de-acidify the world’s oceans.

It is even a potential cure for farting cattle, whose emissions add to global warming. Studies show changing their diet to seaweed can cut methane by 80%. And a trial to feed them supplements is being backed by supermarket Morrisons.
