It is fascinating how there were several news angles that could have been taken from the WWF report, but the media picked up on the bad news/more sensationalist headline that "a vegetarian diet can harm the environment". Actually, the report was looking at the greenhouse gas emissions involved in the UK food system, and the scope for reducing them by 70 per cent by 2050.
The Meat Free Monday article gives a much more balanced assessment of the WWF report. The report said that livestock rearing alone accounts for 57 per cent of harmful emissions from UK agriculture. It indicates that a vegetarian diet (with dairy and eggs), a 66 per cent reduction in livestock production consumption, and technologies to reduce nitrous oxide emissions from soils and methane from ruminants, had the potential to reduce direct supply chain emissions by 15-20 per cent.
