North Ronaldsay, a remote island in the Orkney archipelago off Scotland's northern shore, long ago built a flint wall to keep sheep close to the shore and away from the cows' grazing land. Since then, the sheep have adapted so well to beach life they only eat seaweed, and scientists have found they belch less methane as a result.
In a year, a cow produces about the same greenhouse effect as a car that burns 1,000 litres of petrol, so it's fairly evident how beneficial it would be to reduce livestock's carbon hoof-print simply by altering their diet. Experiments have shown that carbon dioxide as well as methane emissions are lowered when seaweed is introduced into feed. And if he succeeds in creating a nutritious seaweed blend that's palatable to ordinary livestock there would be other environmental benefits too, including being able to source more animal feed locally and sustainably.
The seaweed business was once big on North Ronaldsay and elsewhere in Scotland, so its use as food could be a commercial boon to islanders.
We’ve all been spending a lot more time in the kitchen over the past couple of months, some of us more successfully than others. But if you’re feeling ambitious, aren’t afraid of power-packed spice blends, and have a place to hang raw meat in your home for a few days, consider upping your Covid-19 culinary […]
I have long been a fan of pan-searing steaks and finishing their roast in the oven. Previously, I’d either thaw the steaks in the fridge overnight or I would sous vide them instead of using the oven, and sear them at the end. This technique: thawing the surface of the steak enough to hold seasoning […]
It’s a mandala of crispy fried carbohydrates, and I want to worship every bite.
Father’s Day is June 21st, otherwise known as the roughest shopping day of the year. Don’t get us wrong, Dad deserves an awesome gift for all the great things he gave you. But let’s be honest — buying for your father is often a chore. Your gift has to take into account what he already […]
Even in horrible economic times, a few simple rules hold unshakably true. And one of those rules is that if you possess an in-demand skill, you’ll always find work — and often, at a top market salary, to boot. If you understand Big Data and how to find order from the chaos of massive stockpiles […]
We live in a disposable era. If you can’t fix a broken item with a wrap of duct tape, there’s a very strong likelihood that its next destination is the trashcan. However, that probably leads to a trigger-finger death sentence for many household items that could be saved with just a bit more ingenuity. Before […]
