The Japanese government's decision to contaminate the ocean with large volumes of radioactive waste violates the legal obligations of the United Nations Convention on the Law of the Sea. By turning its back on the clear evidence that the "treated water" still contains harmful radionuclides, Japan has deliberately put marine and human life at risk of radiation exposure.
The ocean release of Fukushima water is the most realistic and safe option available to improve the environment surrounding the nuclear plant. The Japanese government is doing its utmost — through preoperational analysis and preparation — to ensure people's safety, which is why all radioactivity levels meet regulatory requirements and are consistent with accepted international practices.
More information is needed to assess the potential impacts on environmental and human health of releasing the Fukushima water into the sea. Continuing with the pacific discharge plan at a time when the burgeoning climate crisis and growing scale of natural disasters pose significant challenges to the world would be premature.
There's a 28% chance that there will be a major nuclear accident before 2030, according to the Metaculus prediction community.
