Great Pacific Garbage Patch

The Great Pacific Garbage Patch.

Does the name Charles J. Moore ring a bell? Probably not. And why should it? Is he a Hollywood superstar or Grammy Award winner? No. Charles Moore is an oceanographer and racing boat captain. Still doesn’t ring a bell? Ok, so let me introduce him:

Charles Moore loves the ocean, especially the widths of the pacific. This changed in 1997 when he and his crew were on their way back home from Hawaii where they had just won the third place in the “Transpac sailing race”. Moore was looking for a fast way to Los Angeles and therefore decided to take a short-cut through the so called “North Pacific Gyre” – one of the most remote places in the ocean. Most sailors avoid this route and fisherman are seen very rarely. Maybe this is because of what Charles Moore found out: the colourful flashing on the sea-surface doesn’t come from fish but plastic garbage.

The Great Pacific Garbage Patch. For many people, the idea of a “garbage patch” conjures up images of an island of trash floating on the ocean. In reality, these patches are almost entirely made up of tiny bits of plastic, called micro-plastics.

The crew saw plastic parts of all sizes floating on the ocean. Moore recognized disposable razors, bottles, fasteners, CD covers, bags and shoes. “It might sound unbelievable but there was not a single clear spot around us. It didn’t matter where we looked, garbage was floating around us everywhere”, Moore remembers.

As soon as he was back home, the sailor started informing the world about “the worlds largest dumping ground”. The Great Pacific Garbage Patch in the North Pacific is the most well known example of a gigantic environmental disaster. Even experts can only guess its dramatic magnitude.

The Plastic Garbage Patch is twice the size of Texas. But where did this trash come from? Marine biologists estimate that about 80 % of the litter is from land, either dumped directly into waterways or blown into rivers and streams.

Apart from the infamous Great Pacific Garbage Patch, which is made up of plastics, chemical sludge and other marine debris drawn in by a vortex formed by rotating currents, scientists believe there are four other major gyres and associated garbage patches in the Indian Ocean, North Atlantic, South Atlantic and South Pacific.

So, does there float one large garbage-carpet between Hawaii and the USA? Or are there two (each one as large as middle Europe)? Because the majority of garbage is underneath the surface (and in depths up to 10 meters), satellite measurings can only show the vague expansion. However it is sure that there’s plastic garbage everywhere. Particularly high is the density in regions where the air current (as in the North Pacific) causes strong ocean vortexes. There are five of such vortexes that experts know of.

Water covers more than 70 % of the planet’s surface. This makes our rivers, lakes and oceans the lifeblood of our planet. Many of the animals living in these habitats may be extinct very soon. Experts say plastic trash has already killed millions of sea birds and marine mammals.

Marine debris can be very harmful to marine life in the gyre. For instance, loggerhead sea turtles often mistake plastic bags for jellies, their favorite food. Albatrosses mistake plastic resin pellets for fish eggs and feed them to chicks, which die of starvation or ruptured organs. Photo Credit: Wikimedia Commons.

Of the 225 million tons of synthetic materials (which are produced each year), approximately 10 % lands in the ocean at some point. According to the UNEP (United Nations Environment Programme) more than 100 million tons of plastic garbage float at sea.

So what can we do?

The Ocean Conservancy gives a list of 10 tips for helping out:

  • Volunteer for a beach or river clean-up effort.
  • Put trash in a secure, lidded receptacle – most marine debris starts out on land.
  • Properly recycle everything you can in your area.
  • When boating, bring your trash back to shore, and ask your marina to handle waste properly.
  • Less is more: Don’t buy stuff you don’t need, and choose items that use less packaging.
  • Inform and inspire your friends and co-workers to help stop marine debris at the source.
  • Bring your own containers for picnics instead of using disposables. Take your own reusable bags whenever you go shopping.
  • Write to companies or visit local businesses and encourage them to reuse, recycle, and generate less packaging.
  • Put cigarette butts in ashtrays, not on streets, side-walks, or beaches.
  • Tell Congress it’s time to stop trashing our ocean. Take action now and send an email to your representative!

“The Great Pacific Garbage Patch.”

    maybe we should stop buying plastic? Boycott plastic. Hard to do but really we survived without it for so long.

    Thanks for your comment Sarah!
    Sure, boycotting plastic would be great but since it has become such a big part of our life, it’s not easy to live without it (at least for most people). Our generation is so used to plastic (bottles, bags, etc.) that it would take “baby-steps” (which is better than nothing of course) to get things going …
    I think the most important part for now is to get people to KNOW what’s happening out there. After reading about the Great Pacific Garbage Patch for the first time, I was really shocked and it changed my view completely. Today I try to stay away from plastic as much as I can … and this is how to get the ball running.

    To those saying nothing can be done;

    In South Australia, light weight plastic shopping bags are outlawed. Supermarkets use heavier duty plastic bags that customers pay a nominal fee for, so tend to bring re-usable bags.

    And this, from a recent survey of Australia’s coast: “Observationally we do not find full plastic bottles or cans or glass bottles in South Australia and I would likely attribute that to the, to the container deposit scheme that they have there.” Dr. Britta Denise Hardesty

    Thanks for your insight Nick!
    Good to hear that other countries are trying to do something against the plastic pollution!
    Here in Austria, we’ve always had to pay for plastic bags when shopping (supermarket). Still, I feel like more can be done and should be done. Paper bags cost 3 € cents more, so I think supermarkets should just ban plastic bag all together…

    I just recently learned about the environmental effects plastic is causing us. I am partly responsible, which is disturbing to me. What can I do in my life to change the effects I have on the crisis? Plastic is everywhere which makes it difficult to not use. Can we ban plastic?

  6. Nisa

    Hi Tommi!
    Thanks for your comment! Yes, plastic is causing a lot of environmental issues … but unfortunately, it’s everywhere and there’s no escape from it. Governments really need to re-think this issue and invest in new inventions, technologies, etc. to get rid of all the plastic garbage we produce.
    We were actually in Bangladesh last summer and plastic bags are banned there! I wrote an article about this right here, maybe it’s of interest for you:
    I think each and every one of us can just start with small steps. For example to stop buying a plastic bag with each shopping our, but rather bring your own bags. Might be a small step, but if everyone does this, plastic bag production would reduce itself a lot…
    Take care!
    Best, Nisa

    We are all in agreement that plastic polution is a disgrace. How about turning the gyra’s into a resource? Or a half profitable resource sponsored by international effort. Mining of our old rubbish land fill sites is only a 10 years away to extract minerals once thrown away. Perhaps heat is the answer. Plastic comes from oil and oil is money. Buy an old Oil/Gas tanker with plenty of space, convert it to a recycling plant, sail it out to the gyra usng conventional fuel. Once on location, scoup up the garbage, dry it out on deck, roast the plastic in an oxygen depleted reactor vessel to produce a “syn-gas” (which then becomes the ships self generating fuel). Compact what cannot be recycled or turned into syn-gas.
