[QUOTE="white_stuffed, post: 7298254, member: 1751"] They don't need more land, they're going to move it indoors... Extract from the report: [B]Moving horticulture indoors [/B] Horticultural products such as fruit, vegetables and salad crops are grown on 163,000 hectares, or 3% of cropland in the UK. There is considerable scope to improve grassland utilisation, improve productivity and enable land to be used for other uses. Indoor horticulture can raise productivity while reducing nutrient, land and water footprints. 19 Indoor systems such as vertical farming, where crops are grown in stacks in a controlled environment, can raise productivity while reducing the nutrient, land and water footprint.
