But Felix Bock would see boxes, tables, shelves and so on. In 2016, Felix Bock, a doctoral student at the University of British Columbia, Canada, found out people threw away about 100,000 pairs of chopsticks every day in Vancouver alone. He felt the need to do something. So he started the company Chop Value 29 in the same year. The company collected used chopsticks from restaurants, schools and shopping centers in Canada and the US and turned them into furniture and other artworks. Now in its fifth year, with the rapid growth of the company, Bock employs 40 people, and using his special methods of steam and press machines, he has recycled over 32 million pairs of chopsticks. Bock takes pride in his work. And he hopes the idea behind Chop Value will help people rethink what they see as waste. “I believe every small action can help,” he said, “and I am happy that my business provides a new way for people.” Hundreds of restaurants across North America pay a small sum of money to Bock for the recycling of their used chopsticks. Bock doesn't stop there. Now he is busy taking his business to more countries and has set up factories for recycling local wood like chopsticks in many countries.

B.The plan for recycling local wood. C.The advice about setting up a company.

There are so many colorful peacocks（孔雀） here. The peacocks mostly live on the grass land of Dongfeng Square. They are given food freely by visitors. They usually throw food to them, and don't think about at all whether the food is right or not. Some of the peacocks became ill, some even died after eating the bad food given by the visitors. 85 I'm sure most of the visitors who throw food to the peacocks really like the birds, but don't realize that they may be doing them harm. The visitors should be told that what they have done is very harmful to the birds, and this kind of thing must be stopped from happening. Perhaps we can build some small shops beside Dongfeng Square to sell peacock food. For us every person, it is our duty to give more love to these beautiful birds and to look after them carefully. Yours, Sun Yan ( ) 1.Many visitors came to the writer's city to ______.

Do you know any endangered animals? Why are they in danger? _________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ I think there are many endangered animals in the world, such as tigers and pandas. When farmers cut down trees, tigers can no longer hide and hunt. Many tigers are killed by people who want to sell their fur for money. And there are few places where pandas can live. 91 ______________________________________________________________ ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ We are not alone in the world. We human beings could not live without all the plants and animals around us. So protecting wildlife animals is very important. We must take measures to keep plants from being destroyed and stop animals from being killed. If each of us can plant a tree and build a birdhouse, the world will be more beautiful. It is very easy but useful. 92 2023 Blues 162463.55 2023 Blues 179052.92 $$
