01/06/22 - Human food from grass, lab-grown meat and robotic weeders

We look at a future of food production where livestock takes a back seat. We visit a two-million-pound project called 'Pasture to Plate' which is setting out to prove that the nutritional goodness in grass can be extracted and fed directly to humans. And hear about a company hoping to be the first in the UK to produce 100 percent lab-grown meat. Presented by Anna Hill Produced for BBC Audio in Bristol by Heather Simons
