The Pacific is a big ocean but what's at the Fukushima site is a huge volume of radioactive waste. Some has already drained into the bay (no one even knows how much at this point). Once the longer half-life radioactive Cesium is absorbed by small sea life, the radioactivity will become more concentrated in the tissue as it passes up the food chain. What do you have at the top of the food chain, beside us? Well, there are swordfish, tuna, whales, sharks, all of which will have their lives if not their species compromised by this nuclear disaster.
