What really happens to the plastic you throw away - Emma Bryce
-
0:07 - 0:10This is the story
of three plastic bottles, -
0:10 - 0:12empty and discarded.
-
0:12 - 0:14Their journeys are about to diverge
-
0:14 - 0:19with outcomes that impact nothing less
than the fate of the planet. -
0:19 - 0:21But they weren't always this way.
-
0:21 - 0:26To understand where these bottles end up,
we must first explore their origins. -
0:26 - 0:30The heroes of our story
were conceived in this oil refinery. -
0:30 - 0:31The plastic in their bodies
-
0:31 - 0:36was formed by chemically bonding
oil and gas molecules together -
0:36 - 0:37to make monomers.
-
0:37 - 0:43In turn, these monomers were bonded
into long polymer chains to make plastic -
0:43 - 0:47in the form of millions of pellets.
-
0:47 - 0:51Those were melted at manufacturing plants
and reformed in molds -
0:51 - 0:55to create the resilient material
that makes up the triplets' bodies. -
0:55 - 0:58Machines filled the bottles
with sweet bubbily liquid -
0:58 - 1:02and they were then wrapped, shipped,
bought, opened, consumed -
1:02 - 1:06and unceremoniously discarded.
-
1:06 - 1:07And now here they lie,
-
1:07 - 1:10poised at the edge of the unknown.
-
1:10 - 1:15Bottle one, like hundreds of millions
of tons of his plastic brethren, -
1:15 - 1:17ends up in a landfill.
-
1:17 - 1:19This huge dump expands each day
-
1:19 - 1:24as more trash comes in
and continues to take up space. -
1:24 - 1:28As plastics sit there being compressed
amongst layers of other junk, -
1:28 - 1:30rainwater flows through the waste
-
1:30 - 1:34and absorbs the water-soluble
compounds it contains, -
1:34 - 1:37and some of those are highly toxic.
-
1:37 - 1:41Together, they create a harmful stew
called leachate, -
1:41 - 1:44which can move into groundwater,
soil and streams, -
1:44 - 1:48poisoning ecosystems and harming wildlife.
-
1:48 - 1:54It can take bottle one an agonizing
1,000 years to decompose. -
1:54 - 1:59Bottle two's journey is stranger
but, unfortunately, no happier. -
1:59 - 2:02He floats on a trickle
that reaches a stream, -
2:02 - 2:04a stream that flows into a river,
-
2:04 - 2:07and a river that reaches the ocean.
-
2:07 - 2:08After months lost at sea,
-
2:08 - 2:13he's slowly drawn into a massive vortex,
where trash accumulates, -
2:13 - 2:18a place known as
the Great Pacific Garbage Patch. -
2:18 - 2:22Here the ocean's currents have trapped
millions of pieces of plastic debris. -
2:22 - 2:27This is one of five plastic-filled
gyres in the world's seas. -
2:27 - 2:32Places where the pollutants
turn the water into a cloudy plastic soup. -
2:32 - 2:36Some animals, like seabirds,
get entangled in the mess. -
2:36 - 2:41They, and others, mistake the brightly
colored plastic bits for food. -
2:41 - 2:45Plastic makes them feel full
when they're not, -
2:45 - 2:47so they starve to death
-
2:47 - 2:50and pass the toxins from the plastic
up the food chain. -
2:50 - 2:53For example, it's eaten by lanternfish,
-
2:53 - 2:55the lanternfish are eaten by squid,
-
2:55 - 2:57the squid are eaten by tuna,
-
2:57 - 3:00and the tuna are eaten by us.
-
3:00 - 3:03And most plastics don't biodegrade,
-
3:03 - 3:07which means they're destined to break down
into smaller and smaller pieces -
3:07 - 3:09called micro plastics,
-
3:09 - 3:13which might rotate in the sea eternally.
-
3:13 - 3:17But bottle three is spared the cruel
purgatories of his brothers. -
3:17 - 3:19A truck brings him to a plant
-
3:19 - 3:22where he and his companions
are squeezed flat -
3:22 - 3:25and compressed into a block.
-
3:25 - 3:28Okay, this sounds pretty bad, too,
but hang in there. -
3:28 - 3:29It gets better.
-
3:29 - 3:32The blocks are shredded
into tiny pieces, -
3:32 - 3:34which are washed and melted,
-
3:34 - 3:38so they become the raw materials
that can be used again. -
3:38 - 3:42As if by magic, bottle three
is now ready to be reborn -
3:42 - 3:44as something completely new.
-
3:44 - 3:48For this bit of plastic
with such humble origins, -
3:48 - 3:51suddenly the sky is the limit.

We’ve all been told that we should recycle plastic bottles and containers. But what actually happens to the plastic if we just throw it away? Emma Bryce traces the life cycles of three different plastic bottles, shedding light on the dangers these disposables present to our world.
