Environmentalists are worrying about how fast fashion affects the environment. Fast fashion is producing lots of clothes at a low cost. They are put in shops quickly to create a high demand. Companies make 100 billion items of clothing every year. This will grow by 60 per cent by 2030. Fast fashion is having a negative effect on the environment. Many clothes end up in landfills and are not recycled. In addition, the chemicals used to make the clothes cause problems. These damage the health of people working in clothes factories, including children who make many of the clothes.

The way people buy clothes is adding to the problem. People used to go to stores and try clothes on. People took time before they bought clothes. They also wore them for longer. Today, people buy cheap clothes and if they don't like them, they take them back. This is creating a throwaway society. Some people buy clothes and never wear them. The German company Deutsche Welle wrote: "Every year in Europe, four million tons of clothing ends up in the trash. Less than one per cent of this is recycled." It seems the fashion industry is not so sustainable.
