Paper is one of our oldest，simplest and most important inventions.It is the pride of us Chinese，but it also presents a danger to the world.

    First，the making of paper requires the loss of many millions of trees each year.According to The World Counts，between 2001 and 2019，the world lost a total of 386 million hectares of forest.Of the trees that were cut down，42 percent went to paper production.That represents a great part of the world's forests.And worldwide use of paper is expected to double in the next 40 years.Clearly，the planet cannot keep such a high rate of forest Loss.

    The second great problem with paper is that when the paper is used，it is useless.A great deal of wastepaper ends up in rubbish and even landfills （废物填埋场），where it can produce harmful gases.Paper in landfills causes the release （释放） of methane，a gas that is an important factor （因素） in climate （气候） change all around the world.

    One simple way to help out can greatly reduce both of these problems：paper recycling.Instead of cutting down trees，recycle used paper to meet the need of paper﹣making.Effective recycling requires an effort from everyone all over the world.The way to begin is with education and understanding.Once enough people realize the need for recycling，more effective recycling systems can be put into use.

    The need is real.The loss of tees influences everybody on earth.Everyone should do their part to recycle paper and encourage government and industry to do the same.The world will be a better place for it!
