Waste Sorting
Most people haven’t formed the habit of and committed themselves to waste sorting now in China. They would throw their domestic garbage — kitchen refuse, abandoned plastics and papers，broken china and glass, etc. — all into the same public containers, without'thinking whether they are recyclable or not.
This, obviously, will reduce the value of stuff that can be recycled or reused, such as plastics and papers. Besides，the growing amount of garbage makes the building of more landfills necessary, which will worsen the shortage of land. Worse still，disposing of the recyclable waste like plastics by burning will give off toxic smoke which seriously pollutes the air. ID this sense, throwing the trash unsorted should not be advocated, no matter from the perspective of economy or protecting the environment.
On the contrary, if we sort out recyclable waste before throwing them away, the amount of trash will be reduced sharply. Accordingly, the cost of runmng landfills and treating waste will be brought down greatly. Whafs more important, less waste will have to be burned or buried, meaning resources waste and pollution will be reduced. Therefore, economically and eavironmentally, it is of great significance to call for waste sorting.
