a few days ago, i went to the railway station to see my friend off. on the way i saw street leaners burning garbage. i know they were trying to get rid of rubbish in a way they thought wastaking a shortcut. i dont think, however, its proper to clear away rubbish by such a means.

　　burning things does harm to people. its known to all that burning rubbish will give off poisonous smoke and dust which in turn pollute air. many people contract cancer as a result of breathing the polluted air. some of them even die of it.

　　there are many things in rubbish that can be rotten decomposed, such as dry leaves, leftover food, etc. they can make very good fertilizer. so its better to collect them for cropland.
