California defies Trump to ban pesticide linked to childhood brain damage

The EPA had moved to ban chlorpyrifos under Obama, but the Trump administration reversed that effort

California is banning a widely used pesticide that has been linked to brain damage in children, a major victory for public health advocates who have long fought to outlaw the toxic chemical in the agricultural industry.

The state ban on chlorpyrifos, a pesticide used on almonds, citrus, cotton, grapes, walnuts and other crops, follows years of research finding the chemical causes serious health effects in children, including impaired brain and neurological development. The US Environmental Protection Agency (EPA) had moved to ban the chemical under Barack Obama, but the Trump administration reversed that effort, rejecting the scientific conclusions of its own government experts.
