Answer 1

CFC(chlorofluorocarbons)

Although they are beneficial to us in our daily usage major loss is happening rather than benefits

When they are released from Air conditioner and refrigerator's they move into the upper atmosphere and results in depletion of ozone layer

CFC's react with the ozone molecules of ozone layer and results in its depletion resulting in release of Cl(free radical) and oxygen molecules

Due to this depletion,ozone hole is formed by which living beings are being exposed to sun rays leading to skin cancers as they are enriched with UV rays...
