       What is your favourite colour? Ask famous persons like Cate Blanchett, Scarlett Johansson and Bono, and

maybe they will say "green." That's not because these artists particularly like the colour green. 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 hippies (嬉皮士) and 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 (饰品). They are made from natural fabrics (织物) like cotton and

wool. Workers who make the clothes are from countries like Nepal, Kenya, and Bangladesh. People

Tree pays the men and women good money for the clothes they create.

       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.
