    A new study adds to the list of potential health threats from global warming: Higher mercury levels in certain fish. While eating fish is considered part of a healthy diet, it's also a source of mercury -- which, in high enough amounts, is toxic to the nervous system and kidneys.
    Small fish generally have only small amounts of mercury. But when larger predatory fish eat those smaller ones, mercury builds up in their fatty tissue. So, health authorities advise against eating certain long-lived predators, like shark, swordfish, king mackerel and tilefish. That's especially important for pregnant women and young children, since the developing nervous system is vulnerable to mercury's toxic effects.
