What is the Great Pacific Garbage Patch?
00:00:06
Well, first, let's talk about what it's not.
00:00:13
It's not a floating island of trash, like a garbage dump or a landfill.
00:00:16
It's also not the only patch.
00:00:20
They exist all throughout the ocean,
00:00:22
and the Pacific Garbage Patch just happens to be the most famous.
00:00:24
Garbage patches are large areas of marine debris concentration
00:00:28
that are formed by rotating ocean currents called gyres,
00:00:31
kind of like big whirlpools that suck things in.
00:00:34
A garbage patch is made up of tiny plastic pieces
00:00:39
called microplastics that are less than five millimeters long.
00:00:42
It's more like pepper flakes swirling in a soup
00:00:46
than something you can skim off the surface.
00:00:48
You might come across some larger items
00:00:51
like plastic bottles, but it's possible
00:00:53
to sail through a garbage patch and not see anything.
00:00:55
And they're a big problem for the ocean and us.
00:00:59
People often ask why we can't just scoop up
00:01:03
all the marine debris in the ocean.
00:01:06
And the answer is, unfortunately, it's just not that simple.
00:01:08
The first challenge is the sheer size
00:01:12
of these garbage patches.
00:01:14
They're huge.
00:01:15
They're constantly moving with ocean currents.
00:01:17
And there's debris from the ocean's surface
00:01:20
all the way down to the sea floor.
00:01:22
Not to mention all the marine life we would disrupt
00:01:24
if we tried to just scoop up debris.
00:01:27
So what can we do?
00:01:29
Well, the ultimate solution is prevention.
00:01:31
And we need to keep that as our highest priority.
00:01:34
We can reduce, reuse, and recycle
00:01:36
to keep trash out of the ocean in the first place.
00:01:39
And we can participate in things like shoreline cleanups.
00:01:42
It's a lot easier to deal with debris
00:01:44
before it gets to the ocean.
00:01:46
Because until we stop marine debris at the source,
00:01:48
we'll just be cleaning it up forever.
