Farmers have been gathering in London's Parliament Square to protest about what they feel is a lack of support for British food production. Organisers said they have three demands: first, a ban on what they see as 'dishonest' labelling where food imported and processed in Britain can be labelled as British; second, they want the UK to withdraw from the Australian and New Zealand Trade Deals; and third, they want a clear plan for 'food security'. Herring used to be a mainstay of communities up and down the west coast of Scotland. In the early 1900s Scotland was producing 2 million barrels of herring a year, but by the 60s and 70s, stocks of herring had been over-fished and collapsed. Since then, they've struggled to return, but a huge new spawning ground has been spotted by satellite. And, hemp has traditionally been used to make hardwearing textiles - things like ropes and canvas for sails. But it can also be used to build houses using a material called hempcrete! Film-maker, Steve Barron, who's best known for directing music videos, bought some farmland back in 2017, and decided to "grow his own home".
