Environmentalist Dr Rosemary Mason has just written an open letter addressed to three senior officials in Britain: John Gardiner, Under Secretary of State for the Department for Environment, Food and Rural Affairs in the British government; Chris Whitty, the Chief Medical Officer for England; and Chris Wormald, Permanent Secretary at the Department of Health and Social Security.

Her letter focuses on the issue of food and the herbicide glyphosate. But the issues she discusses should not be regarded as being specific to the situation in Britain: they apply equally to countries across the world which are facilitating the interests of global agrochemicals conglomerates.
