I attended Whale Watching cruise to see biological impacts of Fukushima No.1 nuclear power plant accident. Though I have visited various places in the world to see the health consequences of the accident, I have never found any effect against creatures living there. However, there is a little concern that radioactive materials will be brought to overseas by the wind or ocean current. So we have to see the effects against overseas too.
The winter months mark the start of the whale watch season in Hawaii, when approximately 8,000-10,000 majestic North Pacific humpback whales leave their summer home in icy Alaska waters and migrate 3,000 miles to warm Hawaiian waters. Hawaii is the only state in the U.S. where humpback whales breed, calve, and nurse their babies.
Generally speaking, marine animal's growths are so fast than human beings that they are more sensitive to radioactive materials of the environment than us. So I attended Whale Watching cruise to see effects of the accident against creatures which are grown up by Hawaiian food and water. Fortunately, I can see them grown up safely and I cannot find any impact of the Fukushima nuclear power plant accident. It seems that there is no problem for childbirth and child-rearing in Hawaii, USA.

ザトウクジラは11月から翌年の5月までは出産と子育てのため暖かい海で過ごします。このためアラスカから５０００㎞も回遊し、ハワイの海へやって来ます。北太平洋に生息するザトウクジラの 3分の 2 が、ハワイ諸島に集まります。ハワイのザトウクジラは沿岸に集まる傾向があり、海岸からも見られます。ハワイアンハシナガイルカやトビウオも見ることが出来ました。
