Should Japan discharge nuclear waste water from its crippled Fukushima Daiichi nuclear power plant into the Pacific Ocean? This is a question for the international community as a whole to answer, the islands in the Pacific Ocean in particular, not just the Japanese government.

The decision to dump the contaminated water into the ocean is not just a domestic issue of Japan when there is potential danger that the radioactive water may cause lasting damage to the marine ecology and marine resources all over the world.

Earlier this year, Japan unilaterally announced that it would start discharging the radioactive water in spring or summer, just before the International Atomic Energy Agency's task force arrives in Japan for a review.

There are alternative ways to dispose of the nuclear contaminated water rather than just dumping it in the sea, which is an irresponsible choice by the Japanese government, cheap for Japan but expensive for the world. That is what has made the international community so outraged, as dumping such a large amount of nuclear waste water into the ocean is not the only feasible way to solve the problem.

Rather than taking into consideration the possible serious consequences dumping the toxic water into the ocean may cause the marine environment, which will hurt the fisheries the Pacific island countries rely on, and heeding the calls of the international community to reconsider its decision, the Japanese government is stubbornly rushing ahead regardless.

Given that related data and evidence provided by Japan are far from independent or verified, Pacific islands and international organizations have enough reasons to voice their concern about the matter and their opposition to what the Japanese government has decided to do.

Erring on the side of caution is essential in this matter, as it will be too late when the dumped nuclear wastewater causes serious damage to the marine ecology worldwide. It is more than necessary for the Japanese government to think twice about its decision to dump the water into the Pacific Ocean. It should heed the concerns of the Pacific island countries and the rest of the international community.

Japan should seek as much assistance as possible from other countries to find a safer means of disposing of the radioactive water in a cost-effective manner. Japan needs to take a global and long-term perspective on this matter and dispose of the water in a way that causes the least environmental impact, so as to set a good example and precedent for dealing with similar nuclear accidents elsewhere. If so, what Japan has done can be a contribution to humanity.
