Environmentalists are getting more worried about the harmful effects of fast fashion on the environment.

Fast fashion is the mass production of clothes at a low cost, which are put in shops and online quickly     1     (create) a high demand. Manufacturers (制造商) make 100 billion items of clothing every year and this is expected to grow     2     60 percent by 2030. It is reported     3     many of the clothes end up in the trash and are not recycled. The way people are buying clothes also adds to the problem of clothing waste. Many years ago, people went to stores and     4     (try) clothes on. They took more time and thought     5     (careful) before they bought clothes. They also wore them for a much     6     (long) time compared with current consumers. Today, people order cheap clothes on the Internet for     7     (convenient) and if they don't like them, they throw them away. This is possibly leading to     8     throwaway society.

Another negative effect on the environment that can not     9     (ignore) is caused by the chemicals used to make the clothes. These chemicals cause pollution to the environment as well as health problems for people     10     (work) in clothes factories.

Monarchs (黑脉金斑蝶) are the only butterflies known to make two-way migrations, as birds do. In the late summer and early fall, the butterflies typically leave southern Canada and northern and central     1     (region) of the United States. They make a dangerous trip to Florida and Mexico,     2     the weather is warmer. In recent years, monarch populations have been dropping dramatically. To help save the monarchy butterfly population, teens in the North Carolina community formed a club. The Monarch Butterfly Club at East Chapel Hill High School     3     (success) applied for land from the town council for the monarchs’     4     (protect). Club members hope that the garden they     5     (create) will be a safe resting place for the monarchs during     6     (they) long migration. The students plan to get more land from the community in the future. This summer, the club held events for the community. Residents of Chapel Hill were able to help club members plant milkweed for     7     young to eat. “We tell people about the club and our goals     8     (raise) awareness,” said member Kevin Guo, 16. “We’re hoping this can make a change     9     cause people to do more for the butterflies. “According to club member Reymond Zhao, also 16, the situation has to     10     (improve) as soon as possible. He has been planting milkweed in his own backyard for the past few years. “In the future, we might get more schools or clubs into this,” he said. “We need all the help we can get.”
