In Toxic Truth, journalist Lydia Denworth tells the little-known stories of these two men who were among the first to question the wisdom of filling the world with such a harmful metal. Denworth follows them from the ice and snow of Antarctica to the schoolyards of Philadelphia and Boston as they uncovered the enormity of the problem and demonstrated the irreparable harm lead was doing to children.
Lydia Denworth presents insights from studies of everything from at-risk kids in Head Start to noisy cocktail party conversation, from songbirds to signal processing, and from the invention of the telephone to sign language. Weaving together tales from the centuries-long quest to develop the cochlear implant and simultaneous leaps in neuroscientific knowledge against a tumultuous backdrop of identity politics, I Can Hear You Whisper shows how sound sculpts our children’s brains and the life changing consequences of that delicate process.
