Cause and effect Quote by Ed Yong
““Dinsdale and Rohwer found that as humans become more common, so do microbes. From Kingman to Christmas Island, top predators such as sharks went from dominant parts of the reefs to bit-players, coral cover fell from 45 percent to 15 percent, and the water contained 10 times as many microbes and viruses. All of these trends are connected in a complicated web of cause and effect that revolves around a turf war between corals and their ancient rivals: the so-called 'fleshy algae'.””
