Use of CFC is banned in many countries. Give scientific reasons.

Text Solution

Verified by Experts

Chlorine from CFC breaks ozone molecules into oxygen and nascent oxygen. CFC reacts with ozone in the atmosphere and decreases its concentration. This has resulted in a thinner layer of ozone in the air specially over the polar region. Harmful ultraviolet rays would be able to enter the earth.s atmosphere through this thin ozone layer and cause damage to life and diseases like skin cancer in humans. Therefore, its use is banned in many countries.
