There is a Sustainable Livestock Bill progressing through Westminster – it has its 2nd reading on the 12th of Nov.
It is summerised as ‘A Bill to require the Secretary of State to improve the sustainability of the production, processing, marketing, manufacturing, distribution and consumption of products derived to any substantial extent from livestock; and for connected purposes.’ In short, it calls on the UK government to control factory farming of meat and milk that is dependant on imported soya that is grown on deforested land in amazonian regions.
The full Bill can be found at: http://services.parliament.uk/bills/2009-10/sustainabilityoflivestockfarmingandfoodproductionstrategy/documents.html
