Thanks for your concern in your letter about the smog which frequent strikes some areas of China. I'm also very worrying about such a terrible weather. It has brought much inconvenience or rather harm to people's health such as road accident, bad coughs and even lung cancers and so on. It is known to all, good environment comes from careful protection. But we should do what we can protect it. I believe a small step can make a different. Try to drive less and choose air- friendly products. Only when everyone had the environmental awareness can we have a blue sky. Hope to hear from you and share my good ideas.

These days, breaking traffic rules and littering were not uncommon, causing serious harms to life and the environment. That requires lots of effort to change this situation on the part of everyone. As for me, I should start from little things and it won’t be long since I acquire good habits. If I ride a bike, I’ll always keep to the right but never cross a road until the traffic light turns green. If I walk, I’ll never forget use the pedestrian crossing. Meanwhile, I will regard it as my duty to help keep our environment clean and health. Not only will I keep myself on littering and spitting, I will also help clean up the roadside litter whenever be possible. I hope my behavior will make the difference.

Two years ago, when I went to the kitchen for a cup of milk, a magazine lay open on the table drew my attention. An article about environmental protection written by an university professor was on this page. That was a popular magazine which was sold well at that time. From the article, I got plenty of informations. I learned about some problems the earth was faced with and got some suggestions on what they could do to save our planet in an effectively way. From then on, I had been applying myself to protect the environment. While the problem of pollution is universal and we are likely to run out some natural resources, it's time that everybody took action.
Last week several places in our city were blanketed thick yellow fog. Everything disappeared from sights, highways were closed and traffic jams are commonly seen in the streets. Many people, especial children and the old, had to stay indoors. As a result local hospitals were crowded with people which had problems with his noses and lungs. The polluting environment contributed a lot to this. To have a cleaner air we have to do more to protecting the environment. To live a better life we have to push on with the economy, and it will be meaningless if we have to achieve it at the cost of our air.

It is important to deal with the rubbish in cities. Many citizens who unaware of the importance of protecting the environment throw away their rubbish in a way unfriendly to the environment. Rubbish must be treated properly. Thus, it may cause a lot of problems. It may result in the air and water is polluted. When people breathe and drink which has been polluted, we will get ill.
To our happiness, our city has begun to pay attention to the problems. As far as I know, some rubbish is sorted and sent to different factory. Rubbish, such as glass and old newspapers, are recycled. Some harmful rubbish is sent to the certain place and buried. Waste air is cleaned before it goes into the air. Waste water is treated before it is poured into rivers. To protect the environment, the government has passed laws to prevent people from throwing rubbish everywhere, made our city much cleaner than before. As individuals, we should do our part to fight against illegal actions at anytime we find them.
