    What is your favorite color? Ask famous persons like Cate Blanchett, Scarlett Johnson, and Bono (singer

for the band U2), and maybe they will say "green." That's not because these artists like the color green best.

Instead, they are interested in green fashion.

    Green fashion is about making (and wearing) clothes that are good for humans, animals, and the Earth.

In the past, green fashion made people think of ugly clothes. But today, green fashion is different. It is about

looking good and caring about the Earth and other people. You can have interesting clothes and be green.

    Around the world, green fashion is becoming popular. For example, the U.K. company People Tree sells

men's and women's clothing and accessories (配搭物). They are made from natural fabrics (织物) like

cotton and wool. Workers who make the clothes are from countries like Kenya (肯尼亚), and Bangladesh

(孟加拉国). People Tree pays the men and women good money for the clothes they make.

     Singer Bono and his wife also started a clothing company called EDUN. When the clothes sell, EDUN

uses most of the money to help people around the world.
