The
Great Pacific Garbage Patches?
Discovered
in 1997, by an American oceanographer named Charles Moore, the Great Pacific
Garbage Patch is composed largely of a combination of different types of
plastic, and other articles of trash floating out in the middle of the Pacific
Ocean. There are actually several garbage patches, but the in the pacific ocean
there are two. There is an Eastern and Western Pacific Garbage Patch. They are
also connected by an ocean current and pick up trash from all over the world.
The Western Garbage Patch is located between Japan and Hawaii. It is somewhat
smaller than the one in question here, which is the Eastern Pacific Garbage
Patch, located between California and Hawaii.
The
Eastern Garbage Patch has been described as being very large, and compared to
the size of the state of Texas; which is one of largest states, if not the
largest state, located in the United States. Large circular ocean currents
called a gyre hold the trash accumulations.
A
Plastic Soup
The
largest parts of the garbage patch are floating on and below the surface of the
ocean, so it is somewhat hard to see from above in aircraft or even when
driving a boat through it. Over the years it has become more visible though.
This plastic concoction is also located in the middle of the ocean where boats
rarely go, so that is why it may have gone unnoticed for so long. Another fact
to consider is that most trash was more biodegradable 50 years ago.
Shorelines
and beaches become trash dumps with plastic chip dunes and plastic sand beaches
when areas of this toxic mix break free from the gyre and wash inshore. There
are large areas of the ocean patches covered with bulkier pieces of trash that
can be seen here and there, like old bouies, plastic toys, and old fish nets.
Largely
unseen, however, the majority of Garbage Patch contains a high concentration of
small pieces of non-biodegradable
plastic, stringy melting pieces of plastic, Styrofoam, bottle caps,
and anything that doesn't break down basically.
It
is everything that escaped the garbage dumps somehow, or was dumped in the
ocean, and now has broken down into small plastic chips.
Pacific
Garbage Patches Effect on Wildlife
The
negative effects on wildlife have and will be profound with deaths by ingestion
or getting tangled up in the lager pieces of trash like old fishing nets and
those infamous six pack plastic rings. It is obvious that the animals are eating
the trash, with pictures like the one in the above You Tube video. The bird ate
plastic pieces of trash because it is colorful, and in abundance. It died
because birds, or any other kind of animals, cannot digest plastic and they
cannot pass larger pieces of it and it blocks up their system and they die.
They sadly feed it to their young, not knowing that it will kill them.
Scientists
are more concerned however with what will happen when all this plastic gets
down to the molecular level in the food chain of the ocean. It has already been
found that BPA plastic is harmful to rats and humans. Hence, the scare a couple
years back in 2008 with baby bottles containing BPA plastics. All those old
bottle containing BPA are either in landfills now, or will eventually end up
out in the ocean with the rest of them.
Clean
It Up Somehow
More
and more efforts are taking place to better understand this predicament of
ocean pollution and to try to clean up as much as possible before any more
damage can occur. Some water samples
indicate that in areas of the pacific garbage patch off the coast of California
there are more non-marine flotsam particles than there are live marine
particles. In some cases the ratio 6 non live particle to 1 one live particle.
To
remove the this waste would be counter productive. You would be removing the
plastic particle waste along with a large portion of the tiny animals, like
plankton and phytoplankton that make up the basis of the food chain, and that
are mixed up in it. A new study was done on the effect of "Nurdles"
or plastic pellets (pictured on the right), and it was found that they absorb
and hold toxins in highly concentrated amounts. This process is explained in
more detail in the You Tube video above.
It
is still widely unknown what effects the toxic mess of the pacific garbage
patch has had, and will have, upon the life of this planet.
Hubs That Explain More About This
Creepy Manmade Phenomenon:
Human
beings are turning Earth's oceans into plastic wastelands on a massive scale
never known before, and most people still are not aware of it, because popular
news media avoid this critical issue in favor of breezy Hollywood gossip.
There
is a new continent in the Pacific Ocean. Actually it has been forming for
years. It was documented in the 1950's. It is larger now, by some reports twice
the size of Texas. And growing. The most...
