In March of 2011 a massive earthquake and tsunami caused a triple meltdown at Japan's Fukushima Daiichi nuclear power plant. If you're having a difficult time imagining the severity of that, think about how bad a single meltdown at a nuclear power plant is and then multiply it by three.
So, yeah, it's kind of big deal. The triple meltdown resulted in the plant releasing large amounts of radioactive waste, most of which eventually found its way into the Pacific Ocean. Not only is this radioactive waste now washing up along North American shores, it's affecting marine life, some of which is being consumed by people.
Large, bloody tumors have been turning up in sealife in the Pacific, creating worry that the ocean food web may be contaminated. Alaskan fisherman first started noticing these growths in the mouths of the fish they were catching and eventually started finding them on the bodies.
But it isn't just fish that are showing signs of radiation poisoning. Many other animals along the Alaskan coast are showing signs of it as, well, from Polar Bears to Sea Lions. That being said, if you're counting on the government to do something about this, you might be waiting for a while. According to them, there is “no evidence” of health risk from Fukushima radioactivity. They must not be testing the right ocean.
