I've been thinking about becoming vegetarian but I understand that organic farming can't work without livestock. Shouldn't I go on eating some meat?

Laurie: The current level of meat and dairy consumption in the UK is much higher than you would need to maintain a mixed organic farming system - and it is only possible with either very intensive production here, or large-scale extensive production in places like Argentina and New Zealand. The Soil Association and the Henry Doubleday Research Association are very clear that organic production works just as well with plant-based fertilisers (sometimes better). One of the best choices you could make for the environment is to become vegetarian or vegan, or if you must eat meat avoid red meat.
