Question

how CFCS are damage ozone layer ? why are CFCS not harm for the humans?

Answer 1

Dear student,

CFCs are responsible for damaging the ozone layer and cause the formation of the ozone hole in the atmosphere. A rapidly depleting ozone layer allows the harmful UV radiations of the sun to reach the Earth, which are responsible for the following effects:

• Skin cancer
• Cataract (clouding of the natural lens of the eye, thereby causing impairment of vision or blindness)
• Reduction in plant growth
• Decrease in productivity of crops
• Reduced phytoplankton
• Weakening of the immune system
• Eye cancer etc.

So, CFCs are indirectly responsible for the harmful effects on the living organisms and hence very harmful for Humans as well.
