COMMENTARY: The Secret Life of T-Shirts
The Toxic Legacy of Conventional Cotton Clothing, and Why You Should Seek Alternatives
Whether you got it at a rock show, thrift store, vacation spot or trendy boutique, chances are you own a favorite, well-worn T-shirt. Soft, comfortable and cool, the tee is the ultimate laid-back attire, but can just as easily be dressed up with a sports coat or simple skirt and accessories. But there’s more to the T-shirt than wearability—the wardrobe staple leaves behind a serious environmental impact.

Toxic Fields

Most T-shirts are made of cotton, or at least a cotton blend. Unfortunately, the fabric of our lives has a huge impact on the environment and workers’ health. Conventionally grown cotton occupies only 3% of the world’s farmland, but uses 25% of the world’s chemical pesticides. In the U.S., which produces cotton on 1% of agricultural land, 10% of all agricultural chemicals are used on the crop. A 2000 U.S. Department of Agriculture study found that eighty-four million pounds of pesticides were sprayed on cotton in the U.S., ranking it second behind corn. Seven of the top 15 pesticides used on cotton are considered “likely” or “known” human carcinogens by the Environmental Protection Agency.

And it’s not just pesticides. Conventional cotton farmers also use heavy inputs of synthetic, petroleum-derived fertilizers, soil additives, defoliants and other substances, which affect soil, water, air and living things for years to come. Further, 75% of the conventional cotton grown is now genetically modified, a fact that worries critics of the technology, who fear it could contaminate natural organisms and lead to super pests.

Colors for T-shirts are created with dyes that may contain heavy metals.
