The pacific ocean is dying at a rate never before seen and no one can say the word Fukushima Daiichi. This one is man made.
There exist today, I understand, a number of large expanses of ocean area devoid of sealife. One is the size of the State of Rhode Island! A good example of sea-borne destruction is the plastic "carriers" formerly used to contain and carry six-packs of canned beverage. So many of those plastic rings were floating on the Earth's oceans that many water fowl were being found dead, their necks encircled by plastic rings. Evidently, those "carriers" have been eliminated, but for exactly what reason, I do not know. Frank
