AMAZING BAMBOO
What do a bicycle, a chair, a house, and a T-shirt have in common? They can all be made using bamboo! Bamboo is one of the most amazing plants on earth. It has been used by humans for thousands of years. Bamboo may also be one of the most important plants of the future.
Bamboo is very strong. It can be used in most of the same ways as wood. Many kinds of bamboo are actually harder than wood. People all over the world have built houses with bamboo. Bamboo has other uses as well. It makes strong and beautiful furniture. As the young bamboo plants grow, they can be formed into different shapes like circles and even squares! Clothes made from bamboo are quite soft. They are also very good at stopping bad smells. Some companies are even making bicycles with bamboo instead of metal tubes!
Even though bamboo looks like a tree, it’s actually a kind of grass. It’s related to plants like corn and rice. Bamboo is one of the fastest-growing plants in the world. It can grow about three centimeters per hour! Trees take much longer to grow, of course. It takes twenty years or more for a tree to grow to a useful size. Bamboo reaches its useful size in only three to seven years. Many bamboo plants can grow at the same time as one tree. This makes a bamboo farm more efficient than a tree farm. 
The population of the world grows every year. That means that there is more need for materials like wood. But the number of trees is limited. If people used bamboo instead, many trees could be saved. Scientists and inventors are working hard to find other uses for this amazing plant.
