Hawaii deals with Japan's tsunami debris
Kamilo Beach is part of the devastating legacy of the March 2011 Japan tsunami.
"It's disheartening to
come out here and see all this marine debris in an area that's otherwise
so remote, debris that's washing up from other countries," said Megan
Lamson, debris project coordinator for the Hawaii Wildlife Fund.
2012: Japan's endless cleanup battle
Hawaii is in a unique
geographical spot, the center of the Pacific Ocean, to witness the
impact of the Japan tsunami. Debris swirls from Asia to the continental
United States through Hawaii. The islands are, in effect, a comb of the
Pacific.
The nonprofit Hawaii
Wildlife Fund said marine debris has been a problem for years for the
island state and tsunami debris has made things worse. According to
Japan, 1.5 million tons of tsunami debris floated away. The wildlife
fund organizes beach cleanups along Hawaii's shorelines and struggles to
keep up with the marine debris, made up primarily of plastic.
Lamson pulled out part of
a beer crate that read "Exclusively for Kirin Beer" in Japanese. She
also found a Suntory Whisky bottle stamped "Japan." Lamson also found a
small vitamin drink container with Japanese text. Since fall, the
wildlife fund and the National Oceanic and Atmospheric Administration
have found refrigerators, freezers, buoys and even an intact fishing
boat, all with Japanese text.
But most disturbing to
Lamson are a couple of soft plastic bottles with bite marks. "Marine
life in the ocean are mistaking plastic for their natural food," Lamson
said.
Lamson may suspect it,
but Lesley Jantz, a NOAA fishery biologist with the observer program,
can confirm it. Jantz has been studying the impact of marine debris in
fish.
In her lab, Jantz sliced
open the stomach of a lancetfis. You may never have heard of
the lancetfish, a sometimes 4- to 6-foot long fish with enormous teeth.
But bigeye and yellow fin tuna eat lancetfish. Tuna ends up on our
plates.
Jantz pulled out a 12 by
12 piece of indigestible black plastic. "It would be difficult to pass
through the system," said Jantz. "I've found several fish with the same
black plastic bag, just like this, even larger. If it gets to a certain
size, the fish is going to feel like it's full."
Jantz conducted a study
that included 64 fish of varying species. Twelve percent of them, she
said, contained plastic. When she looked just at lancetfish, 45% had
plastic. "One concern that we have and don't know is if any chemicals
from the plastic are absorbed into the tissue of the fish, which is a
problem if consumed by a fish that we consume. That's definitely the
next step, what is the impact?"
Across the island in
David Hyrenbach's lab, the impact of plastic debris is apparent among
the animal species he studies: birds. Hyrenbach cut open the bellies of
some albatross for it. Plastic pieces spilled out of the belly of a
2-month-old albatross. Eighty percent of the stomach was packed with
plastic.
Hyrenbach, an assistant
professor of oceanography at Hawaii Pacific University, pulled out a
small bottle top. "Toothpaste top?" he said. "No, cap of a medicine
tube." He reached into the stomach again. "Oh, it's a brush, you see?"
There were the unmistakable bristles of a hairbrush.
"Morally, this is
terrible. How is this possible? Majestic, far ranging, beautiful birds,
in a pristine place of the pacific, the northwest Hawaiian islands, you
open them up and this is what you find," said Hyrenbach.
He grabbed a box, packed
with toy soldiers, lighters and brushes. He explained that he pulled
all the items out of albatross from Hawaii. "Every bird I looked at had
plastic. Some had a little bit. Some had a lot. Everybody we looked at
had plastic."
NOAA said most of the
debris affecting the island cannot be tracked to any particular country,
even Japan, because the plastic is often so weathered and broken by the
time it hits Hawaii. "We don't really know the full impact of this type
of debris. It adds to an existing problem that we have across the
world," said NOAA Pacific Islands Regional Coordinator Carey Morishige.
"But it is quite eerie to see an item you think may have come from
Japan, someone's home, to sit on a beach thousands of miles away. It
brings home the fact beyond the marine debris issue this is first and
foremost a human tragedy." It should serve as a reminder, Morishige
said, that "the land and the oceans are incredibly connected."
