It never occurred to me that the human body and a coral reef have a lot in common--until I spoke to Forest Rohwer for this podcast. Rohwer is a microbiologist at San Diego State University, and he studies how microbes make coral reefs both healthy and sick. Just as we are home to a vast number of microbes, coral reefs depend on their own invisible menagerie of algae and bacteria to get food, recycle waste, and fend off invaders. But as Rohwer writes in his new book, Coral Reefs in the Microbial Seas, we humans have thrown this delicate balance out of kilter, driving the spread of coral-killing microbes instead.
