the cause and effect between of both this paragraphSo what will it take for sustainable food production to spread? It’s clear that scaling up must begin with a sort of scaling down — a distributed system of many local or regional food producers as opposed to just a few massive ones. Since 1935, consolidation and industrialization have seen the number of U.S. farms decline from 6.8 million to fewer than 2 million — with the average farmer now feeding 129 Americans, compared with 19 people in 1940.It’s that very efficiency that’s led to the problems and is in turn spurring a backlash, reflected not just in the growth of farmers’ markets or the growing involvement of big corporations in organics but also in the local-food movement, in which restaurants and large catering services buy from suppliers in their areas, thereby improving freshness, supporting small-scale agriculture and reducing the so-called food miles between field and plate. That in turn slashes transportation costs and reduces the industry’s carbon footprint.
