Today more and more building designers（设计师）are thinking about how to make buildings that are good for the environment.They use materials that are easy to find or recycle old materials to make new buildings.Here are some examples.
    In August 2013，Ban，a building designer from Japan，made a new church for people in New Zealand.The church is mainly made of cardboard（硬纸板）.It stands 25 meters high，with a plastic top to protect the building from rain.The church can last up to 50 years，and it can be recycled.Another example is from Taiwan.This building is designed by Arthur Huang，and it is made of 1，500，000 recycled plastic bottles!The building is strong，beautiful and comfortable.
    The last example is made by Choi Jeong-Hwa，an artist from South Korea.He used old doors to decorate（装饰）an old，ten-floor building.He painted bright，beautiful colors on the doors.The building is a colorful surprise in the street.
    The use of recycled materials to build public buildings is growing.They not only cost little，but also are beautiful and good for the environment.Maybe soon，these buildings will appear in your city!
