प्रश्न
Why is ozone layer getting depleted at the higher levels of the atmosphere? Mention one harmful effect caused by its depletion.
उत्तर
The ozone layer is getting depleted at the higher levels of the atmosphere due to the action of chlorofluorocarbons (CFCs). CFCs are used in refrigerators and fire extinguishers.
A larger amount of UV radiation is reaching the Earth as a result of ozone layer depletion. The ecology can be impacted by UV radiation because it interferes with photosynthesis in plants and kills plankton and decomposers. UV radiation can harm the immune system, create cataracts in the eyes, and lead to skin cancer in people.
