Industrial-scale beef production is impacting global climate, but scientists have found a way to make cattle-rearing more environmentally-friendly.

Around 70% of methane emissions from agriculture is due to cows. Cows release methane, a by-product of their digestion, either through belches or farts.
Researchers have discovered that by supplementing a cow’s diet with a type of red algae seaweed, known as Asparagopsis taxiformis that the amount of methane released is reduced by as much as 80%.

Red algae seaweed contains a compound called bromoform, which is responsible for interfering with the enzymes that product methane. Unfortunately, bromoform is found only in the red sea algae, not freshwater macrophytes, darn!
