The small size and apparent wastefulness of the livestock sector is readily apparent. It takes a huge amount of land and other resources to generate a relatively small amount of product. A surprising proportion of biomass in recent years has gone into ‘renewable energy supply’, where it is deemed ‘zero-carbon’. http://peterharper.org/services/courses daily 0.75 2025-04-09 https://images.squarespace-cdn.com/content/v1/5212032ee4b0a807b652e71a/1414674589053-DUPWN07XHQ56MVCXQXWM/Weekend+course+in+Korea.JPG Courses Students and teacher of an international postgraduate course in Kyoto, Japan, 2006. The students came from China, South Africa, USA, Sweden, Uzbekistan, Indonesia, UK, Philippines, and of course Japan. Teaching sessions were held in the mornings, and in the afternoons the entire class would cycle for a study visit relevant to the day's theme. On the way, every day an international picnic.

In the winter, the vine is cut back, allowing the low sunshine in. During summer the leaves shade the space underneath, and the plant (a kiwi vine) also provides fruit. This is an ancient idea, widely used in Mediterranean countries, but popularised by the Permaculture movement.

On the left are genuine bridges going in the right direction, but (constrained by politics and economics) they don't get very far.
