Through activities I know more about the place where we lived a few decades ago. The sky is so blue and water is so clear at that time. But a few years later, sky becomes grey and unclear . These are the results of emissions discharged form the increasing number of urban motor vehicles . The more and more refrigerators using at home give off fluoride emissions which can affect the ozone layer, giving rise to the ozone hole. All these made our living spaces become worse and worse.Therefore we must strive to make the environment better and let sky and water of our hometown return to which a few decades ago.

There is still a long way to go before them be solved successfully. The world is now paying more attention to global warming caused by air pollution. It is helpful to change the situation of air pollution if we do some good to our environment in our daily life. Next Let’s talk about some energy-saving measures what we can do.
Energy-saving measures: We should develop the habit of turning off the lights if there is no one in the room . Although this is the small thing of daily life ,it is very important to start with this kind of small things. To switch off the television sets, tape recorders at any time .
Water-saving measures: To turn off the faucet after washing hands and cleaning mouth. Don’t leave the taps opening all the time when you take a bath. We can do a lot on water-saving, I think there will be improvement as long as each of us care about it.
