Half a century on from Rachel Carson’s seminal Silent Spring, debate rages over GM food labelling proposals
Fifty years ago, marine biologist Rachel Carson ignited the modern environmental movement with the publication of Silent Spring. It was an ecological alarm call – an attack on what she believed was the overuse of pesticides and the potential harm they might cause to humans and wildlife – and a call for a progressive science-focused view of modern agriculture and food.
Her deeper, ecological message is often overlooked by her most ardent supporters.
