Fukashima is still leaking and plastic is still killing. Coral is till dying off and poisonous fish are a norm. Things are not looking good folks.
Your worried about Fukishima? LOL Seriously you need to get an education. Google "Asia ocean pollution" and be prepared to be truly horrified. Within a matter of years many fish will not be edible because of the mercury pollution from China alone. Most of the plastic being dumped in the oceans today comes from Asian countries like China and Vietnam and not the US.
Fukushima has had a negligible impact on the oceans. The oceans are not more radioactive. Believe it or not, these things are monitored. Elevated caesium-137 levels can be measured in fish, but twice nothing is still nothing. The natural radioactive potassium in the oceans still vastly outweighs the new radiocaesium. Unless you're fishing in right in Fukushima lagoon, you will not encounter any radioactively contaminated fish.
