　　Trees are useful to men in three important ways：They provide them with wood and other products(产品), they give them shade(树荫), and they help to prevent drought and floods．

　　Unfortunately, in many parts of the world, men have not realized(功能)is the most important．In their eagerness(渴望)to make money from trees, some people have cut trees down in large numbers, only to find that without them they have lost the best friends they had．And besides(此外), they are usually too careless to plant and look after new trees, SO the forests slowly disappear．

　　These scientists were especially vocal during the United Nations Climate Change Conference, which just wrapped up in Warsaw, Poland. The timing of the conference and Typhoon Haiyan was an eerie coincidence, but perhaps the concurrence offered a wakeup call for all.

　　Christiana Figures, Executive Secretary of the UN Framework Convention on Climate Change (UNFCCC) said, “We are witnessing ever more frequent extreme weather events, and the poor and vulnerable are already paying the price.”

　　Scientists claim that storms like Typhoon Haiyan are an inevitable result of the effect greenhouse gases are having on our environment. Environmental analysts claim that rising temperatures around the globe and changing weather patterns are all part of the same problem.

　　This isn’t breaking news. We’ve heard the warnings for years. The UN has been hosting the Climate Change Conference since1995.But the changes that need to be made are huge. Added to this, the developed nations and developing countries have competing interests that are difficult to settle. The issue of who takes responsibility becomes difficult to resolve.

　　We may feel far away from Poland and resolving conflicts between countries, but we mustn’t feel far away from the issue. When we watch neighboring countries suffer in severe weather, when we hear reports of increasing global temperatures, when we walk outside and find it difficult to breathe the Shanghai air, we know we have a very real problem. So what are we going to do about it? Are we making every-day choices that can have a positive impact? Are we reducing our carbon footprint? Are we choosing to walk, ride a bicycle or take public transportation instead of a car? Are we recycling? Are we turning off the lights and electronics whenever possible?

　　The problem is complex, but saving our earth starts with each of us taking simple steps.
