One of the reasons tropical forests are being cut down so rapidly is demand for the hardwoods that grow there. Hardwoods, as their【C1】______suggests, tend to be denser and more durable than softwoods. But their unsustainable logging【C2】______not only forests but also【C3】______creatures and the future prospects of the people who lived there.
It would be better to【C4】______softwood, which grows in cooler regions in【C5】______managed forests. Softwoods are fast-growing species that【C6】______80% of the world’s timber. But the stuff is not durable enough to be used outdoors【C7】______being treated with poisonous chemicals to protect it【C8】______insect pests. These chemicals eventually【C9】______out into streams and rivers, and the wood must be retreated. 【C10】______, at the end of its life, wood that has been treated with such kind of chemicals in this way needs to be disposed of【C11】______.
One way out of this problem would be an environmentally【C12】______way of making softwood harder and more durable—something that a Norwegian company called Kebony has now【C13】______.
Kebony stops wood from rotting【C14】______placing in a large container containing a 【C15】______called furfuryl alcohol(糖醇), which is【C16】______from the waste left over when sugarcane(甘蔗)is processed. The container is then pressurised, 【C17】______the liquid into the wood. Next the wood is dried and heated to 110℃, which makes the cell walls of the wood thicker and【C18】______.
Of course, treating wood makes it more【C19】______. But because it does not need to receive【C20】______treatments, it should prove economical over its lifetime. [br] 【C14】
