French MPs gave themselves a round of applause for approving legislation to reintroduce a banned pesticide last month. A figure rose from the public gallery to shout: "You are supporters of cancer ... and we will make it known." Fleur Breteau made it known. Her outburst and appearance she lost her hair during chemotherapy for breast cancer " boosted a petition against the "Duplomb law" to well over 2m signatures. On Thursday, France's constitutional court struck down the government's attempt to reintroduce the pesticide acetamiprid " a neonicotinoid banned in France in 2018 but still used as an insecticide in other EU countries as well as the UK " in a judgment that took everyone by surprise. The ruling said the legislature had undermined "the right to live in a balanced and healthy environment" enshrined in France's environmental charter. For Breteau, 50, a battle is won but the struggle goes on. "The law is a symptom of a sick system that poisons us. The Duplomb law isn't the real problem. It's aggravating an already catastrophic system," she said. "We are living in a toxic world and need a revolution to break the chain of contamination in everything ... If people don't react we'll find ourselves in a world where we cannot drink water or eat food that is uncontaminated, where a slice of buttered bread or a cup of tea poisons us. It will be a silent world, without animals, without insects, without birds."
