Bamboo is a kind of wild grass. There are more than 1450 species of bamboo that grow across the world. It is hollow(空的), so it is very light.

For thousands of years, bamboo has been used in many different ways—from food to medicine to clothing. It is also used for furniture or man-made Building products such as flooring and window covers. However, bamboo is not often used as a building material in the developed world.

Kent Harries, a professor at the University of Pittsburgh, sees bamboo as a great building material because of the following.

First, it is strong. The strength of at least three species of bamboo is similar to steel. Besides its strength, Harries says that bamboo has other features that make it a great building material. He says it can keep its shape and strength even under pressure.

Second, it’s very tall. It can grow up to 20 meters and it supports its own weight, even in the strong wind.

Third，bamboo also grows quickly. Bamboo that is suitable for construction needs much less resources than wood. It lives on the rainwater, spring water and sunlight. The harvest cycle of bamboo is about 3 years. Softwoods such as pine (松树) and spruce(云杉) have a harvest cycle of about 10 years. And hardwoods that come from flowering plants such as maple(枫树) and walnut(胡桃树) need more than 30 years.

People usually think bamboo is only for poor people. But in many countries，bamboo is used for building floors and roofs and even beautiful houses.
