A Hawaii-based marine conservation expert is "disappointed" by Japan's decision to release treated nuclear wastewater into the Pacific Ocean.
The country is going to release one-million-tonnes of diluted water from its Fukushima nuclear plant, which was hit by a tsunami in 2011.
The process could start as early as Thursday and take up to 30 years to complete.
Robert Richmond, Director of the Kewalo Marine Laboratory at the University of Hawaii at Manoa, says the Japanese government has missed an opportunity to develop a less harmful approach.
Richmond spoke to Corin Dann.
