Besides giving off gases and dusts into the air,humans produce waste that is poured on the environment.Often,this waste produced by major industries and people is harmful to both nature and human life.
One of the main causes of the large amount of dangerous waste is that people do not realize how large a problem it is.Because it can be simply removed and sent to a landfill(废渣填埋场）,the problem is often believed to end there.In addition,industries have often shown an unwillingness to find ways to deal with dangerous waste because of the related expenses.Many industries and governments build simple landfills to store waste,and often just pour waste chemicals into nearby bodies of water.Often,chemicals used for industrial production cause dangerous forms of waste.The amount of these chemicals has increased greatly in the past,but it is often difficult and expensive to get rid of these chemicals or to store them in a way safe to human life and the environment.
Every year,major health problems result from dangerous waste.Sadly,it is often only after someone has died or become seriously ill that governments will take measures to reduce levels of harmful waste.
Some governments have realized how serious the dangerous waste problem is and are now trying to settle this problem.They are also trying to limit the amount of waste industries are allowed to produce.
Not only governments but ordinary people as well must work together to solve the problem.They can choose not to buy those products which require the production of dangerous waste,and produce less harmful waste themselves.Many scientists think that waste production can be cut.The waste can be reduced by at least one third using existing technologies and methods.

除了把气体和灰尘排放入大气中，人类还把产生的废物向周围环境倾倒。常常，大工业和人产生的废物对自然和人类生活都有害。
造成大量危险废物的主要原因之一，是人们没有认识到这是一个多大的问题。因为它能完全被搬走，送到废渣填埋场，人们常常认为这个问题在那里就算完结了。另外，由于有关费用的问题，企业常常不愿意想法处理危险的废物。很多企业和政府建起简单的废渣填埋场存放废物，而且常常只是把废化学物品倒进附近水域。工业生产所用的化学物品常常造成多种形式的危险废物。这些化学品的数量近年来大大地增加，但要处理掉这些化学品，或者以一种对人类生活和环境安全的方式存放它们，常常是很困难的，而且花费巨大。
每年都有危险废物引发的重大的健康问题。可悲的是，只有在有人死了或者病危之后，政府才采取措施降低有害废物排放量。
一些政府已经意识到危险废物问题是多么严重，现在正努力解决这个问题。他们还正在试图限制允许企业产生的废物量。
不仅政府，而且普通人也必须一起共同努力来解决这个问题。他们可以决定不买那些在生产过程中会产生危险废物的产品，而且他们自己也少产生有害废物。许多科学家认为，可以减少废物的产生。用现有的技术和方法至少可以使废物减少三分之一。
