Fashion isn't very environmentally-friendly because it makes people buy things they don't need, just because they're new. We want to take care of the environment, we don't want to pol­lute the air and we don't want to waste energy and resources. But we also want to be fashiona­ble. How can we buy fashionable clothes and protect the environment?
Old styles are fashionable again, so one way is to buy second-hand clothes — recycled clothes. Another way is to buy' fair trade clothes. These clothes are either recycled or made in a ' way that protects the environment. They also protect the people who make the clothes.
Surprisingly, white cotton is one of the least environmentally-friendly crops of all. To pro­tect the cotton, the growers use chemicals that pollute water, make farm workers ill and kill wildlife. New materials, such as hemp and bamboo, grow quickly and are more environmental­ly-friendly. These materials are very soft, and look fantastic. The best materials are coloured using natural dyes, made from plants.
Environmentally-friendly clothes are practical but until now they were often dull. Now fashion-designers are working with these materials and the clothes are beautiful as well. So now we can buy fashionable clothes that are also environmentally-friendly.
【小題1】Why do people often buy things they don't need? Because_.
A.new things can be more comfortable
B.everyone wants to be fashionable
C.people are richer than before now
D.people care about the environment
【小題2】What's the topic for paragraph 2?
