Harmful and Needless Emission of Refrigerant and Countermeasures

Refrigerants used in refrigerators are an important source of ozone depleting substances released into the atmosphere,and can have a significantly negative effect on the hole in the ozone layer.But most emission of refrigerants is man-made,unreasonable and needless.Since in most emission cases the refrigerants are contained in the refrigerators,we can retrieve them by some technique that changes the 'manual emission' into manual retrieving.To promote the retrieval action and diminish the pollution,society can use economic,administrative and technical countermeasures,which can create a 'good-cycle' both 'harnessing pollution and earning income simultaneously',reinforce the motive of retrieving,and retrieve most proportion of refrigerants used by all refrigerators.This 'good-cycle' method can be easily promoted,and also a valuable way to promote other forms of environmental protection.The three countermeasures have almost no social cost,even no cost at all.
