It is true that we live longer, travel faster and own more things than we used to． We have 1 great progress in science and technology． But we 2 have lots of problems． One of the major problems 3 that at the same time as we 4 our industry and modern life, our natural environment 5 polluted．

　Sometimes the air is too polluted to 6 and the rivers are 7 filthy to swim in or to take water 8 ． In the big cities the roads are too crowded to drive 9 ． In the countryside 10 farmland is being taken up by development projects． Today, things 11 open land , clean water and good air are getting scarcer and scarcer ． But industry and modern life 12 be enemies of beauty． Progress 13 be ugly ．It doesn’t have to 14 all the countryside around it． We can have both beauty and progress 15 we really want to ． There are 16 things the government should do to overcome the environmental problems we face today ． First of all, the government should regard the protection of the environment as one of the most important issues it 17 on its agendA．The government should consider the environment 18 jobs ． Secondly, more money should be given to scientists to research the problems 19 by the pollution of the environment． Thirdly, strict laws and fines should be imposed on factories which do not 20 environmental laws ．It isn’t just the government that should pay attention to the environment． We as individuals should also be prepared to do something to help the environment． We should stop littering around． We should dispose of rubbish in the regular rubbish bin． We should recycle aluminum cans, bottles and newspapers．Above all, we should increase our environmental awareness．

　As I have said earlier, our planet is being polluted． We will not be able to live on the planet much longer unless we protect and improve it the best way we can．
