Phyllis Omido, a single mother from Mombasa, Kenya took action to close a local lead smelter after finding out that her child was suffering from lead poisoning from her breast milk. She collected data in the form of local knowledge and hospital visits with patients suffering from lead poisoning, and founded the Center of Justice, Governance and Environmental Action. With proof of the plant’s impacts, Omido organized letter-writing campaigns and street protests, and in 2014 the smelter ceased operations. Throughout the duration of the protests, Omido was arrested and attacked by armed men. Today, Phyllis Omido continues to push for a clean and safe environment for all Kenyans.
