After the success of campaigns to get investors to divest from fossil fuel companies (some 400 institutions have committed to pulling money from coal, oil and gas companies to tackle climate change), factory farming is the next target. Fast food chain Subway is latest to join the backlash against antibiotic use in the farm sector. It has launched a new chicken sandwich made with meat from animals raised without antibiotics. The move is a sign of the growing consumer and business interest in the welfare and environmental impact of animals reared for meat, dairy and eggs, with most of the blame directed at intensive, factory-style farms.
