Bisphenol A is an estrogen mimic, found in some of the plastics we use in our everyday lives. How much of a problem is this endocrine disrupter? Are there other compounds that should concern us?
Biologists suggest that some natural experiments could help illuminate this question. For example, cats are experiencing an unusually high number of thyroid problems. What could be triggering this hormone disturbance? Alligators in Florida lakes also demonstrate abnormal development. What can they teach us?
