20．United Nations Climate Change Conference
The U．N．Climate Change conference opened in Copenhagen，Denmark on Dec.7th with some 15，000delegates and observers from nearly 200countries attending what is called the last best chance for an agreement to combat（与…战斗） global warming．
Their aim is to find common ground，including on reduction of greenhouse gas emissions，promotion and transfer of new more eco-friendly technology and the necessary funding to make this possible，especially for the less developed and poorer nations．It also means coming up with long term vision and cooperation for the future．
Most scientists believe the warming trend is mainly caused by human activity，especially the use of fossil fuels（矿物燃料） and the cutting down of forests．Skeptics（怀疑论者） say global warming is part of a natural cycle of climate change．
In Copenhagen，experts and officials alike are  putting the emphasis on what people and governments can do to cut the emission of greenhouse gasses．
Scientists say a 25to 40percent cut in carbon-dioxide emissions is needed to control global warming．The European Union，China，and India have already pledged（保证） reductions．The United States is waiting for Congressional（国会的） approval for a proposal put forward by the Obama administration．
Barack Obama，President of the United States said，"Each of us must do what we can when we can to grow our economies without endangering our planet--and we must all do it together．We must seize the opportunity to make Copenhagen a significant step forward in the global fight against climate change.."
Desmond Tutu，Archbishop of South Africa said，"Worldwide，we have the chance to start turning the tide of climate change，but only if all governments commit themselves to a fair，binding（有约束力的） and sustainable climate agreement in Copenhagen．"

17．Our environment isn't as green and beautiful as it should be．There are steel（钢铁）monsters blocking out the sun，blowing out dangerous smoke，and letting out poisonous chemicals into rivers，cars producing harmful waste gas，people throwing out waste in a wrong way and all other kinds of sources that ruin the planet．Facing current environmental problems，people need to do their best to save the earth．
You can see many big garbage dustbins in the streets．They're not there for a show，but for you to drop your waste．We should realize that what we do does count．So next time you get that urge to throw gum or a chocolate package out of the car window，or"accidentally"drop as you walk down the street，ask yourself how much waste you've been contributing to the environment with that bad habit going on for years．
At home，the first thing we can do to protect the environment is avoid letting water run continuously and make sure that taps（水龙头）are not leaky（漏的），which would help greatly in scrimping．Another is to use energy-saving lights，and turn them off before you leave the rooms．It is not only energy-saving，but also cuts down electricity costs．
Recycling is a method to make items reusable．Many things you want to throw out can be made into new products through the reproducing process．Use your imagination to come up with ways on things that you can use again．
Pass the message of simple ways to save the environment on to kids．Starting with kids is a good way of teaching the message early in their lives，in the hope that they can carry it forward as they grow older．
With environmental protection awareness in mind，we can do what we can，for the results are to have a big effect on the planet．As long as we do our part，the world is one small step closer to being saved．
