environmental problems are becoming more and more serious all over the orld. for example, cars have made the air unhealthy for people to breathe and poisonous gas is given off by factories. trees on the hills have been cut do n and aste ater is being poured continuously into rivers.furthermore, herever e go today, e can find rubbish carelessly disposed. pollution is, in fact, threatening our existence.
the earth is our home and e have the duty to take care of it for ourselves and for our later generations. fortunately, more and more people have realized these problems. measures have been taken to cope ith these problems by the government. la s have been passed to stop pollution. i hope the problem ill be solved in the near future and our home ill become better and better.
with the improvement of our living standard, more and more people can afford a car. as a result, our roads are more often than not crammed with cars. however, with more and more waste gas being discharged by the cars, the problem of air pollution becomes even more serious. so nowadays we advocate to lead a low-carbon life.
my suggestion is we should ride bikes more often instead of driving cars.by riding a bike, we can not only exercise our body but also protect our environment. why not have a try, my dear friends?
now, our side of the car constant more up, the environment also increasingly worse! that the air around us there are many harmful substances. therefore, we want to sue around things start to do. for example, we can go to school by bike or walk, it can exercise. if you have time can use less elevator, many climb stairs. we can not only physical exercise, but also to protect our environment.
what’s more, we should realize that only from our planet can we obtain our sheltering, food, cloth and so forth.
to everyone on our planet,
over the past years, floods, droughts, landslides, and dust-storms have frequented our planet, the only habitat of human beings. several days ago, tsunami(海啸) has swept the southeast asia, which has caused enormous damage. all these have sounded an alarm to human beings.
