1
Consider the classic white t-shirt.
2
Annually, we sell and buy two billion t-shirts globally, making it one of the most common garments in the world.
3
But how and where is the average t-shirt made, and what's its environmental impact?
4
Clothing items can vary a lot, but a typical t-shirt begins its life on a farm in America, China, or India where cotton seeds are sown, irrigated and grown for the fluffy bolls they produce.
5
Self-driving machines carefully harvest these puffs, an industrial cotton gin mechanically separates the fluffy bolls from the seeds, and the cotton lint is pressed into 225-kilogram bales.
6
The cotton plants require a huge quantity of water and pesticides.
7
2,700 liters of water are needed to produce the average t-shirt, enough to fill more than 30 bathtubs.
8
Meanwhile, cotton uses more insecticides and pesticides than any other crop in the world.
9
These pollutants can be carcinogenic, harm the health of field workers, and damage surrounding ecosystems.
10
Some t-shirts are made of organic cotton grown without pesticides and insecticides, but organic cotton makes up less than 1% of the 22.7 million metric tons of cotton produced worldwide.
11
Once the cotton bales leave the farm, textile mills ship them to a spinning facility, usually in China or India, where high-tech machines blend, card, comb, pull, stretch, and, finally, twist the cotton into snowy ropes of yarn called slivers.
12
Then, yarns are sent to the mill, where huge circular knitting machines weave them into sheets of rough grayish fabric treated with heat and chemicals until they turn soft and white.
13
Here, the fabric is dipped into commercial bleaches and azo dyes, which make up the vivid coloring in about 70% of textiles.
14
Unfortunately, some of these contain cancer-causing cadmium, lead, chromium, and mercury.
15
Other harmful compounds and chemicals can cause widespread contamination when released as toxic waste water in rivers and oceans.
16
Technologies are now so advanced in some countries that the entire process of growing and producing fabric barely touches a human hand.
17
But only up until this point.
18
After the finished cloth travels to factories, often in Bangladesh, China, India, or Turkey, human labor is still required to stitch them up into t-shirts, intricate work that machines just can't do.
19
This process has its own problems.
20
Bangladesh, for example, which has surpassed China as the world's biggest exporter of cotton t-shirts, employs 4.5 million people in the t-shirt industry, but they typically face poor conditions and low wages.
21
After manufacture, all those t-shirts travel by ship, train, and truck to be sold in high-income countries, a process that gives cotton an enormous carbon footprint.
22
Some countries produce their own clothing domestically, which cuts out this polluting stage, but generally, apparel production accounts for 10% of global carbon emissions.
23
And it's escalating.
24
Cheaper garments and the public's willingness to buy boosted global production from 1994 to 2014 by 400% to around 80 billion garments each year.
25
Finally, in a consumer's home, the t-shirt goes through one of the most resource-intensive phases of its lifetime.
26
In America, for instance, the average household does nearly 400 loads of laundry per year each using about 40 gallons of water.
27
Washing machines and dryers both use energy, with dryers requiring five to six times more than washers.
28
This dramatic shift in clothing consumption over the last 20 years, driven by large corporations and the trend of fast fashion has cost the environment, the health of farmers, and driven questionable human labor practices.
29
It's also turned fashion into the second largest polluter in the world after oil.
30
But there are things we can do.
31
Consider shopping secondhand.
32
Try to look for textiles made from recycled or organic fabrics.
33
Wash clothes less and line dry to save resources.
34
Instead of throwing them away at the end of their life, donate, recycle, or reuse them as cleaning rags.
35
And, finally, you might ask yourself, how many t-shirts and articles of clothing will you consume over your lifetime, and what will be their combined impact on the world?

为什么要通过这个视频练习口语？
在学习英语的过程中，口语表达能力至关重要。观看这段关于“T恤生命周期”的视频不仅能够帮助你了解时尚产业对环境的影响，还能为你提供丰富的口语练习素材。通过shadow speech的方式跟读视频，你可以提高英语口语练习的效果，增强听力理解。同时，了解讲话者的情感和语气，可以提高你的语言表达能力。这段内容有利于增进你对实际情境中英语的理解，使你能够更自信自然地进行日常交流。
语法与表达的背景
视频中使用了一些关键的语法结构和表达。以下是三个值得注意的句式：
- “...is made of...”——用于解释材料或成分，从而让听众明确产品结构。
- “require a huge quantity of...”——强调需求量的句式，常用于描述生产过程中的资源需求。
- “is called...” ——用于定义或命名某种事物，有助于清晰传达信息。
这些短语在日常对话中非常实用，通过模仿这些句型，你可以轻松提高英语口语练习的流利度和准确性。
常见的发音陷阱
视频中可能会有一些发音较为复杂的单词或短语。例如：
- “pesticides”——这个词的发音可能会让许多学习者感到困惑，注意元音和辅音的组合。
- “environmental”——通常在连读时会有口音变化，练习时要注意将每个音节发清楚。
- “pollution”——在快速对话中，发音可能会被简化，注意保持清晰度。
在进行提高英语发音的练习时，提及这些单词，使用shadowspeak的方式重复几遍，可以帮助你克服发音困扰，建立更坚实的发音基础。
什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
