Todays, many people participate in movement for sustainable development. The aim of this movement is not only for human's profit but protection of nature. There are many kinds of green building that do not pollute the environment. For example, A school has many large windows to get sun lights. Sun lights can transform to electricity, so, it can save more energy. Also, there is rooftop garden to reduce temperature variation so, it can save cooling and warming charge. There is big tank to store water too. Water in the tank can be used in gardening and toilet. Not only these activities are sustainable development.

Comment:

There are many changes to construct buildings more greener. In the past, many people destroyed environment because of their own profit. But, If they thought more carefully, probably they didn't do that. Destroying environment is not profit to human. So now, people take part in recycling, building green, protecting environment and making eco-friendly business. These are good symptoms that our environment is getting healthier.

School uniform

School Uniform

For a long time, Almost all korean students are allowed to wear school uniform. But, there are lots of controversial issues about wearing school uniform even todays. Wearing school uniform has both advantages and disadvantages. However, I think wearing school uniform is more beneficial to korean students.

Firstly, School uniform prevent students from aggravating a rupture between friends. If students wear ordinary clothes, they will always think about their appearances. So, They waste their time for useless things. Also, They want to wear expensive clothes, gay costumes and feel superior to other friends. It costs lots of money to show them. But, if, students should wear school uniform, that situation will not happens.
Secondly, People who disagree with wearing school uniform insist that school uniform is so uncomfortable to act or study. But todays school uniforms fit students very well and are made to exercise and study well. Also many designers make efforts to make comfortable school uniforms.
Finally, School uniform do not ignore individuality. Students can show their characteristics to other people in different ways not just their appearances. We must not jump to a conclsion that only ordinary clothes show student's individuality.
As these reasons, I agree with wearing school uniforms. It can make students sense of belongings so, they act more carefully when they are outside with wearing school uniforms. Therefore, I really advocate wearing school uniform.
