A new push for federal funding of genetically-modified crops has touched off a battle among non-profit organizations seeking to help developing countries and ease world hunger. On one side is the Bill & Melinda Gates Foundation and The Chicago Council for Global Affairs, which supported a study calling for the federal government to finance new agricultural biotechnology research. Using this study, Senators Richard Lugar and Robert Casey have introduced the Global Food Security Act (SB 384), which would direct more than $7 billion in government subsidies to biotech companies for development of new GM crops.
