The Lifecycle of a T-shirt
We all probably have a lot of T-shirts, but do you ever stop and think about the influence of a T-shirt on the planet? You'd probably be surprised to learn what's involved in the lifecycle of just one T-shirt.
There are 5 major stages: material, production, shipping, use and disposal. The material stage involves farming, irrigating, fertilizing, harvesting and ginning. While cotton is a natural fiber (纤维) and not as harmful to the environment as manmade fibers, it still takes a toll in the material and production stages. Commercial cotton farming uses a large amount of water, and the use of pesticides (杀虫剂) is widespread across the globe, especially in cotton farming. Studies have shown that farmers spend around $4.1 billion on pesticides annually, of which 25% was spent on cotton crops in the US.
Once the cotton is grown and harvested, so begins the production stage: spinning, knitting, bleaching, dyeing, cutting, sewing, etc.——these processes also use a great deal of water and energy. Commercial dyes and bleaches are harmful pollutants and can eventually pollute groundwater.
After the T-shirt is produced, it enters the transportation stage. This often involves overseas shipping. Take a look in your closet. Chances are that most of your cotton garments (衣服) are made in China or India. Garments can be shipped via plane, ship or truck…, all of which spill CO₂ into the atmosphere. Calculations show that CO₂ emissions from light trucks alone amount to 1.15 pounds per mile.
Once the T-shirt reaches the retail market, it is purchased. This stage may seem like the leastenvironmentally damaging part. But consider the number of times you've washed and dried your favorite T-shirt. Washing machines are certainly becoming more efficient. However, the average American household does 400 loads of laundry per year, using about 40 gallons of water per load. Such excessive water use is combined with the large amount of energy used by dryers.
The final stage of life is disposal. This releases harmful emissions, or involves a landfill where cotton takes years to break down. Current US records show that an estimated 15% of clothes and shoes are recycled, which means that consumers send a shocking 85% of these materials to landfills.
We all need new clothes every once in a while, but let's all try to keep in mind what goes into the production of clothing... It has a real impact on the planet.
There are a lot of things you can do to help reduce your impact. Reuse and recycle clothes. If they're too worn out to wear, cut them up and use them as cleaning rags. Donate them to charity or another organization that recycles textiles. When possible, make an effort to buy organic cotton. Turn down the thermostat on your washer, and line dry your clothes when the weather will allow it.
