Sam Elsom’s Instagram feed is looking pretty bare. The fashion designer and photographer hasn’t posted a fashion-related image on his feed since mid-2018, but following an interview with the Australian Financial Review, the reason why is clear – it’s because of seaweed. Specifically, Asparagopsis taxiformis, a variety of seaweed which has been shown in scientific tests to reduce the methane output of livestock such as cows. This means that seaweed could be a major solution to climate change.
