The earth scale change of climate has brought a new kind of natural disaster and the developed and complicated city system is holding a latent risk of expanding the damage artificially。 Also people has been spoiling the health since the immense quantity of chemicals have been produced and already used in pursuit of convenience and various toxic substances have been produced unintentionally and accumulated in environment。 Therefore, We need some countermeasures from the viewpoint to prevent the city environment form disaster and to manage environmental risks。 So we will develop and improve a new risk management system and a disaster prevention system to preserve and create the city environment where people feel easy and sound in their life。
Environmental problems are becoming more and more serious all over the world. 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 down and waste water is being poured continuously into rivers.Furthermore, wherever we go today, we can find rubbish carelessly disposed. Pollution is, in fact, threatening our existence.
The earth is our home and we 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 with these problems by the government. Laws have been passed to stop pollution. I hope the problem will be solved in the near future and our home will become better and better.
环境问题变得越来越严重的世界各地。例如,汽车污染的空气影响了人们的呼吸,工厂释放污染的气体,山上的树木被砍伐。在山上的树木被砍伐,污水不断被倒进河流。另外,无论我们走到今天,我们可以找到垃圾随意丢弃。事实上,污染是威胁我们的生存。
地球是我们的家园,我们有责任照顾它为我们自己和我们的后代。庆幸的是,越来越多的人已经意识到这些问题。已经采取了措施来应对这些问题的政府。法律已经通过停止污染。我希望这个问题在不远的将来能得到解决,我们的家园将会变得越来越好。
