Since poison gas was invented for combat in World War I, our industrial use of neurotoxic chemicals has increased dramatically and with it, the number of children with special needs. A 2016 study by Northwestern University found that babies conceived near toxic Superfund sites were more likely to have disabilities than their siblings born to the same mother after toxic waste was removed. An overwhelming amount of evidence from institutions like Harvard’s School of Public Health now supports the conclusion that industrial chemicals are altering human development.
