Dr. Tyrone Hayes discusses his journey as a scientist: initially just a “young boy who really liked frogs,” he would go on to earn worldwide fame for his work on the harmful effects of the pesticide atrazine. Arguing that “those who have the privilege to know, have the duty to act,” Dr. Hayes details his decade-long feud with Syngenta, the manufacturer of atrazine, as well as his acute observation that those who suffer most from the environmental impacts of harmful chemicals tend to be the socioeconomically-disadvantaged and racial or ethnic minorities. At the University of California, Berkeley, and in ponds around the world, professor Tyrone Hayes studies frogs and other amphibians. He's become an active critic of the farm chemical atrazine, which he's found to interfere with the development of amphibians' endocrine systems. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
