15、ocked during the race by the pollution he found on the oceans.There was rubbish floating everywhere.So when he got back to Sydney he decided to organize a clean-up day.He began with Sydney Harbour.In 1989 he got 40,000 volunteers to help him clean it up.They collected tonnes of old car bodies,plasti
16、cs of all kinds,glass bottles and cigarette butts.It was so successful that Ian organized the first Clean Up Australia Day in 1990.This time more than 300,000 people offered to help and it was another success.Since then it has become a yearly event with more and more people coming to help.Heres a ta

31、 good to us.But do you know that many of the environmental problems our country faces today result from our fossil fuel dependence.The environment faces air pollution,global warming,acid rain,and several other very serious problems because of our use of fossil fuels.Over the last 150 years,burning o
32、f fossil fuels has resulted in more than 25 percent increase in carbon dioxide in our atmosphere.Carbon dioxide is one of the main factors in global warming which is negatively affecting everyone.Fossil fuels also affect water pollution,land pollution,and thermal pollution(heat pollution).Coal minin
33、g is one of the causes of pollution in the environment.After the mining is completed,the land will remain barren.Materials other than coal are also brought to the surface in the coal mining process,and these are left as solid wastes.The production,transportation,and use of fossil fuels are to blame for the effects of pollution on the environment.Then what should we do?We should spare no effort to improve our environment.Please save energy and use fewer fossil fuels in our daily lives.We have onlyone earth!Homework:Prepare a talk about“Clean Up China Day”.
