How do the clothes you buy wear out the natural world? To take stock of the damage you have to account for the materials, water and energy that went into making a garment, and the greenhouse gas emissions, chemical pollutants and other byproducts associated with its disposal.
For example polyester, a kind of plastic widely used in T-shirts, is made from oil – a fossil fuel. If you throw it out it degrades slowly, and chemicals from its dyes and surface treatments leach into the soil.
