　　Waste sorting is not a popular convention in our country, though it should be. Garbage bins filled with all sorts of recyclable and non—recyclable wastes mixed together are seen everywhere. People still haven’ t formed the habit of sorting wastes.
　　The neglect of waste sorting will bring about a series of problems. First of all, it causes a mass of waste of resources that could have been recycled or reused. Secondly, the growing amount of mixed rubbish will take up a lot of space in the landfill site, which will worsen the land shortage problem. Last but not least, it will increase the cost of waste treatment.
　　Waste sorting should be advocated, no matter from the perspective of economy or environment. Everyone should do their best by starting from daily life. More importantly, more campaigns for waste sorting should be conducted to raise the public awareness.
