Great Pacific Garbage Patch
We’ve written about the Great Pacific Garbage Patch in the past on a few occasions. However, it seems it’s a hot topic right now (perhaps getting some national TV news coverage tonight?), so I thought I’d revisit it and drop in some updated information on the huge garbage patch in the Pacific Ocean.
First of all, some orientation:
The Great Pacific Garbage Patch is actually two “garbage patches” in the Pacific Ocean, each about the size of Texas! Yes, Texas. Due to ocean circulation patterns, debris (especially plastic, which takes quite a while to disintegrate) accumulates in certain spaces. Think of it like there are two giant toilets out there that, when flushed (and they’re always flushing) slowly turn the water in the whole, gigantic ocean. Yep, something like that. (There are actually a lot of them around the world, such as the “Great Atlantic Garbage Patch,” but the Pacific has two of the biggest, and two of the most polluted.)
With hundreds of thousands of pieces of debris, especially plastic, floating around out there, you know it’s causing problems for ocean life. As reported before, plastic has been found in about 9% of Great Pacific Garbage Patch fish. Additionally, dead sea turtles and other marine life have been found to have huge stomach-fulls of plastic and other garbage.
An interesting (read: sad) note I just read is that about 10% of all plastic produced in the world ends up in the ocean.
Of course, huge hurricanes and tsunamis, like the tsunami that hit Japan last year, have an even greater impact on this topic. They pull even more debris, plastic, and God knows what else out into the oceans. Perhaps, with the anniversary of that horrible Japan tsunami and Fukushima nuclear meltdown approaching, more people are being informed about this Great Pacific Garbage Patch of plastic.
It’s always good to remember, what goes out into the environment, comes back into us. While it may not be evident at first thought, the plastic and other synthetic materials that sea life consume ends up in the stomachs of many humans, in one way or another. Even for vegetarians, like myself, there are many sea vegetables that may actually be taking some of this in as well. Not fun to think about, perhaps, but this is the world today. Fix it or live with the consequences.
