Plastics are a ubiquitous, inescapable part of daily life. They have many seemingly irreplaceable, inexpensive and convenient uses. But there is a dark side to some of them that goes far beyond the painful photographs of albatross chick tummies stuffed with discarded cigarette lighters or turtle necks strangled by six pack rings. Some of them are exceedingly hazardous to life, even at what appear to be low doses. Much of the hazard arises because they contain chemicals that interfere with hormone signaling: endocrine disrupting chemicals (EDCs). By hacking the hormone signaling systems that control fetal development, they can set in motion physiological processes that can lead to a wide array of diseases and disabilities. Intense study of EDCs began in the 1990s. Since then, millions of dollars have been invested in this scientific field, yielding thousands of research papers. Pete Myers will lay out the core central themes that have emerged in this field over the last two decades: low doses matter a lot; wha
