If you really want to know what happens, then go to Japan and stay there; eat the seafood, drink the water and bathe in the the environment. Take notes, leave a journal for posterity and have children. Post your data to social media, words and pictures; leave it to the future to assess the outcome. You are too close to the inception point, with little data to make a valid extrapolation. Given 20 or 30 years worth of data will give a meaningful direction for further extrapolation. Given 100 years of data, an hypothesis will redefine the direction and possible results.
