Japan is moving in a positive direction on its fisheries policy and ensuring the marine ecosystem remains sustainable, said David Rockefeller Jr., an environmentalist and a descendant of one of the most influential business families in the United States, but he noted in an interview with The Japan Times on Monday that the country needs to do more to tackle the issue of plastics polluting the world's oceans.

The management of marine species is becoming more feasible, as scientists now have a better understanding of the globe's fish populations, Rockefeller, a philanthropist, a sailor and an advocate for healthy oceans said. He noted plans for reform by Japan, therefore, are positive and necessary. "We don't want our grandchildren criticizing us because today we didn't act," he said,

Rockefeller, who is in Japan for business, as well as for other ventures, was speaking on behalf of the nonprofit organization Sailors for the Sea, which he established in 2004.
