Japan has begun discharging nuclear-contaminated water into the sea despite opposition. The plan involves releasing 7,800 cubic meters initially, aiming for 31,200 tonnes by March 2024, spanning 30 years. Global response is swift: Thailand doubles seafood inspections, South Korea maintains import restrictions, Malaysia imposes strict checks, China enforces a seafood ban, and the U.S. reduces Japanese imports. Experts predict radioactive materials will spread globally over time, with potential ecological and health risks. Concerns focus on seafood safety, but contamination could affect various products. Authorities emphasize vigilance and monitoring to mitigate potential harm.
