Question

why should the use refrigerators be avoided in ecosystem

Answer 1

because usually refrigerators use coolants which is usually made if CFCs(chlorofluorocarbon). this usually reacts with the tri atomic molecules of oxygen which is simple the ozone. This causes the ozone to get depleted if the production of CFC increases. So the use of refrigerators should be avoided in ecosystem.

Answer 2

we should avoid refrigerators in our ecosystem because refrigerators contains thee CFC's which contain large amount of chlorine , fluorine and carbon . these affects the ozone layer which cause depletion in that and it leads in increment of  of black hole i.e. a hole in ozone layer at Antarctica .

ozone layer is most important because it protects us from the harmful ultraviolet rays of sun . but CFC's were banned because they announced the uppermost atmosphere and the chlorine would break down the molecules of ozone , which shield the earth from UV rays of sun and a refrigerant , the HFc were slightly less efficient than CFC's , requiring little more electricity .
