How we make and buy clothes is hurting the planet. Here's a solution.

Have you ever considered the environmental cost of your favorite pair of jeans? And what about the clothes that hang in your closet unworn? 

The impact of apparel manufacturing on the Earth's climate is certainly on the minds of executives at athletic wear company Lululemon, which is choosing Earth Day this year to launch a resale program to take back worn garments from customers and sell them at a discount. The goal: keep clothes in circulation longer, limiting Lululemon's carbon emissions by reducing unnecessary production and consumption by consumers.
