在巴西的许多城市,都耸立有绿色的高楼大厦。原来这高层建筑都是用一种叫“生态砖”的材料建成的。“生态砖”是一种特殊设计的空心砖,里面填满草籽、树胶和有肥料的土壤。把这砖砌在建筑的外层,草籽就会发芽生长,形成苍翠欲滴、别具特色的墙,整个建筑也就成了绿色世界了。这种绿色楼房不但美观,而且冬暖夏凉,既减尘又防噪声,有益身心健康,还有助于提高人的工作效率。这些生态楼房已成为巴西的独特景观。 In many cities in Brazil, there are towering green buildings. It turned out that this high-rise building was built using a material called “ecological brick.” The “ecological brick” is a specially designed hollow brick filled with grass seeds, gums and soil with fertilizer. When this brick is built on the outer layer of the building, the grass seeds will germinate and grow, forming a lush, distinctive wall, and the entire building will become a green world. This kind of green building is not only beautiful, but also cool in winter and cool in summer. It not only reduces dust but also prevents noise and is beneficial to physical and mental health. It also helps to improve people’s work efficiency. These ecological buildings have become a unique landscape in Brazil.
