Tepco in an attempt to save money have decided to dispose Fukushima radioactive waters into the sea. If the water is safe like what Japanese and American governments said, they could have just recycled these within the country e.g. farming, instead of pouring into the sea. According to what i heard, it takes only 57 days for the radioactive matetials to permeate the Pacific Ocean, and just a few months to flow through the world's oceans (any oceanographer to confirm this?) This has become an entire human race problem. The next few generations of humans may face radiation problem from consuming seafood and all seafood derivatives. No one is safe and immune if they eat seafood.
