it is clear that in both the uk and sweden, the majority of dangerous waste products are buried underground. by contrast, most hazardous materials in the republic of korea are recycled.

looking at the information in more detail, we can see that 82% of the uk’s dangerous waste is put into landfill sites. this disposal technique is used for 55% of the harmful waste in sweden and only 22% of similar waste in korea. the latter country recycles 69% of hazardous materials, which is far more than the other two nations.

while 25% of sweden's dangerous waste is recycled, the uk does not recycle at all. instead, it dumps waste at sea or treats it chemically. these two methods are not employed in korea or sweden, which favour incineration for 9% and 20% of dangerous waste respectively.

some people think the university education is to prepare students for employment. while we admit that preparation for employment is an important function of education, it is not the only one. we should see this issue with an all-sided view. in the perspective of society, education is for improvement. students make use of what they have learned to create new theories and tools. this is the way in which our human society develops. and also, through education, government can teach people how to be appropriate citizens, thus in this way, people’s moralities and behaviors are constrained in a value system and the social stability can be maintained.

in the perspective of individuals, education can enrich personal lives. through education, we can explore different cultures and customs. thus in this way education can open our eyes and broaden our mind. and education can also meet interests of each student.

while of course, all the functions mentioned above have one common prerequisite: one can make a living in the first place. for this society is practical, many university students have studied for four years, but their ability to deal with practical things is too low to be acceptable. so education should provide the basic general knowledge to university students, so that they can be get employed and make a living. and if a nation wants to develop and to compete with other nations, it needs skilled workers to support economic development and to maintain the people creative, which can only be achieved through education.

so it has some sense to realize that students’ preparation for employment is the function of education, but it has far more function which should not be neglected.

human beings have only one earth, it is the natural resources of human survival, people want to live a happy life, we must consciously protect the natural environment, love the earth.

however, in recent years, the earth's environment has become increasingly bad: global warming, hurricanes, heavy rain and other severe weather, "sars", avian flu and other infectious diseases occur, to human life and the work poses a serious threat and a lot of inconvenience. these are the result of people constantly "hurting" the earth. large tracts of forest are cut down, green green mountains are excavated, beautiful grassland into desert, clear river into a turbid flow. the forest is less, the grassland bald, grassland shortage, dark water, so that people living environment deteriorated, breathing the air worse, the living environment by many harmful things "encroachment", the virus took the opportunity to get into the people in the body, we humans will suffer from some terrible disease.

a few days ago, i saw in the newspaper such a comic: a person sitting on the treetops, is cutting his sitting tree branches. "well, it's funny." some people might think so. do not you think about it, is it just funny comic? is it not in the irony of us? do not you realize that it warns us that mankind, while destroying the environment, is unknowingly hurting himself.

when you walk in the street, if you want to spit, what would you do? if you choose to spit on the ground, then you think no, you are harm yourself? a sputum contains a lot of bacteria, when the sun will be breeding, infection. similarly, when you cut down a tree, when you dig a piece of grass, when you put the dirt into the river, do not you think it is in the destruction of the environment, "hurt" yourself?

as the saying goes: "predecessors planted trees, descendants shade," the previous people gave us large tracts of forest, green, we left to future generations what is it? is the bare desert, or the dense woods, you must choose is the dense woods. so what hesitation, let us all consciously protect the environment, consciously care for the environment, consciously greening the environment, improve our living environment, create a better future!
