Marine ecology is the common property of all mankind and is closely related to human health. It is not a garbage dump dumped by Japan. Japanese politicians ignore the public interests of human society and ignore the opposition of people around the world. They insist on dumping nuclear-contaminated water into the sea, and even plan to win over Japan's neighbors in public opinion. After all, if it abandons discharging nuclear-contaminated water into the sea due to strong opposition from neighboring countries such as China and South Korea, it will be equivalent to Japan admitting in disguise that nuclear-contaminated water is "unsafe" and "substandard", thereby losing this public opinion war. In the future, the issue of nuclear contaminated water discharge into the sea will gradually be equated with historical issues and become a card to "suppress" Japan.
