World-Renowned Biology Prof to Speak on Pesticides

Hawaii SEED News Release

A state-wide speaking tour of world-renowned University of California Berkeley Professor of Integrative Biology Dr. Tyrone Hayes will include Molokai on May 16. Paul Towers from Pesticide Action Network will be speaking as well, presenting an overview of pesticide use nationally and internationally and the significant role that Hawaii plays as ground zero for open-air pesticide experimentation.

The Molokai event will be held on Friday, May 16 at 6 p.m. at the Molokai Community Health Center. Other special guests will include Lorrin Pang, M.D. of the Hawaii Department of Health and Jeri Di Pietro, president of Hawaii SEED.

Dr. Hayes is best known for his research findings that Swiss Chemical Company Syngenta’s herbicide atrazine is an endocrine disruptor that not only demasculinizes male frogs but transforms them into fully functioning reproductive females. Dr. Hayes is also an advocate for critical review and regulation of pesticides and other chemicals that may cause adverse health effects. Dr. Hayes has presented hundreds of papers, talks, and seminars on the role of environmental chemical contaminants in global amphibian declines and in the health disparities that occur in minority and low-income populations.

Despite his research being contested by Syngenta, it was used as the basis for the settlement of a multimillion-dollar class action lawsuit against them. According to the lead plaintiff’s lawyer Stephen M. Tillery, “Science has been fighting an uphill battle against giant pesticide manufacturers like Syngenta who claim that a little weed killer in your drinking water won’t hurt you. Independent scientists now believe that even trace amounts can harm you and your children for generations to come.”

According to Joy Shih, a doctoral candidate at the University of Hawaii’s School of Ocean and Earth Science and Technology, “the chemical poses a particular threat in Hawaii because of the islands’ geography.” She thinks atrazine should be banned. “I think of Hawaii as one giant watershed,” she said. “There is no inland, from the tops of the mountains, everything flows into the ocean. So anything that you apply that is water soluble ends up in the ocean. Fish are definitely affected and coral is affected.” Shih said that studies show that atrazine causes coral bleaching and harms phytoplankton, which rest at the bottom of the aquatic food chain.

According to Pesticide Action Network, there are many viable ways of producing corn and growing food without relying on atrazine. Healthy, resilient farming systems can grow food to feed Hawaii, without the use of hazardous pesticides. Syngenta, which is based in Basel, sells more than fourteen billion dollars’ worth of seeds and pesticides a year and funds research at some four hundred academic institutions around the world.
