  • What if plastic pollution gets worse?


  • Plastic pollution is one of the biggest environmental issues our planet faces today.


  • Plastic slush fills our oceans, plastic trash litters our landscapes, and even the air we breathe has microscopic pieces of plastic polluting it.


  • This is Unveiled, and today we're answering the extraordinary question: What if plastic pollution gets even worse?

    歡迎收看 Unveiled,我們今天要回答一個特別的問題:如果塑膠污染加劇,會發生什麼事?

  • The problem with plastic is that, most of the time, it never fully disintegratesoften, it's specifically designed that way.


  • And, given that many plastic products are single-use items, we're producing more and more and more of a material that'll never go away.


  • True, some plastics can be recycled, but that doesn't mean that everyone does soleaving wrappers, water bottles, pieces of packaging, and everything else to clog up ecosystems.


  • Around 8 million tons of plastic winds up in the ocean every year.

    每年都有近 8 百萬噸的塑膠被丟入海洋。

  • It's predicted that this type of pollution will triple in the next decade, and that by 2050, there could be even more plastic in the water than fish,

    這種污染預計在接下來 10 年會變成 3 倍,而到了 2050 年,海裡的塑膠可能甚至比魚多,

  • which is devastating news for all marine life, with aquatic creatures either mistaking plastic for food and ingesting it, or getting trapped in casually discarded human trash.


  • According to recent figures, almost half of marine vertebrates were wiped out between 1970 and 2012, but if plastic use continues as it has done, the stats will get worse.

    根據最新數據顯示,有近一半海洋脊椎動物於 1970 至 2012 年間滅絕,若是人們持續使用塑膠,情況將更糟。

  • We'll see entire species forced to extinction and increasingly severe knock-on effects across the food chain as predators consume plastic via their prey.


  • The amount of plastic in the ocean is now so immense that at least five huge garbage islands have formed around the world.


  • Made up only of the more buoyant plastics, these floating trash heaps are set to grow and grow.


  • The Great Pacific Garbage Patch is the largest of all.


  • Also known as the GPGP, it floats between California and Hawaii and takes up an area twice the size of Texas, holding around 1.8 trillion pieces of plastic, including some dating back to the 1970s.

    這座又稱為 GPGP 的垃圾島漂浮於加州和夏威夷間海域,大小是德州面積的兩倍、含約 1.8 兆件塑膠,有些甚至能回溯至 70 年代。

  • And remember, these patches are only made up of plastic on the ocean's surface.


  • It's estimated that 99% of all plastic in the water is unaccounted for below the waves,

    估計有 99% 的海洋塑膠是在海平面下,去向不明。

  • and these often-smaller pieces pose an even more sinister threat.


  • At 5 millimeters long or less, microplastics are small enough to go unnoticed to the human eye,

    最長為 5 毫米的塑膠微粒,小到人類肉眼基本上無法察覺,

  • but these tiny particles that never truly break down like organic matter does can remain in the sea for centuries.


  • It's no longer a mistake on behalf of the fish to eat this type of plastic, but an unavoidable accident.


  • In fact, microplastics are so small they can be absorbed into an animal's body simply through respiration, or even via tiny plankton carriers.


  • Again, microplastics can make their way up the food chain even as far as seafood-eating humans, so plastic pollution directly impacts human health.


  • And it's not only the oceans we should worry about, either.


  • Landfills overflowing with plastic are concerningly normal nowadays.


  • And, as these areas encroach into other natural environments, the spread of non-biodegradable litter widens.


  • It can even affect our drinking water supply, with plastics leaching toxic chemicals into the groundwater in some areas.


  • At the very least, these materials wind up in rivers, and eventually end up in the oceans again.


  • Finding a solution to the issue, beyond simply not using plastic, is a problem, too.


  • Simply incinerating plastic is plain dangerous for anyone nearby.


  • And more broadly speaking, it contributes to air pollution, the depletion of the ozone layer, and climate change.


  • And it throws microplastics into the air, inflicting on us the same problem that sea animals face,


  • meaning every breath you take risks microplastics in your lungs, possibly your bloodstream, and eventually other parts of your body.


  • Completely cleansing the environment of the plastic that's already here currently seems an almost impossible task that will at least take a very long time.


  • But preventing the problem from getting worse is doable.


  • It rests on changing habits, increasing recycling, and reducing our reliance on plastic in general, both individually and as a society.


  • Right now, plastic pollution stretches to almost every corner of Earth.


  • But, as long as it's mass-produced and irresponsibly disposed of, the garbage heaps, landfills, and floating islands of yesterday's trash will continue to grow, and the negative effects will continue to pile up.


  • And that's what will happen if plastic pollution gets worse.


  • What do you think?


  • Is there anything we missed?
