Looking fashionable feels good. However, did you know that doing so could be extremely bad for the planet?

Making clothes requires lots of energy. For example, cotton fields have to be watered. Jeans must be dyed (染色) and then dried. According to scientists, making 1 kilogram of clothes produces 23 kilograms of greenhouse gases on average.

However, clothes are spending less time in shops and at homes than ever. Consumers (消费者) today keep almost every article of clothing only half as long as they did 15 years ago. That causes a large amount of waste.

Some clothing companies and designers have realized this problem. H & M, for example, was the world’s largest buyer of “better cotton” last year. The cotton needs less water to grow. It also requires fewer pesticides (农药). The Swedish brand has also stopped using a chemical that pollutes the environment when making waterproof (防水的) clothes. Nike, meanwhile, has invented a new method of making shoes. It reduces waste by 60 percent compared with traditional cutting and sewing.

More long lasting clothes could help, too. Tom Cridland is a British designer. The clothes that he designs all go through a special treatment. Cridland says they can last more than 30 years.

Unfortunately, not all clothing companies and designers, think they should be responsible for the environment. Some companies do not care about their carbon footprint at all.

What can we do? In some western schools, students are encouraged to fix their jackets and trousers. Clothing companies there send vans to campuses to help them do it. Another solution is to think twice the next time we buy new clothes. Some clothes may not look very fashionable, but they could be good for our planet.
