Why is the depletion of the ozone layer a concern for humans?
It leads to increased water pollution.
It protects us from harmful radiation.
It increases soil fertility.
It promotes plant growth.
It protects us from harmful radiation.
The ozone layer, located in the stratosphere, acts as a protective shield by absorbing the majority of the Sun's harmful ultraviolet (UV) radiation. Depletion of this layer allows increased UV-B radiation to reach the Earth's surface, which causes severe health risks to humans, including skin cancer, cataracts, and immune system suppression.

The Vienna Convention (1985) and the Montreal Protocol (1987) are the primary international agreements focused on protecting the ozone layer by phasing out the production of ozone-depleting substances (ODS) like CFCs.
Ozone layer is primarily found in the Stratosphere (15-35 km altitude).
Chlorofluorocarbons (CFCs) are the main culprits behind ozone depletion.
UV-B radiation is the specific type of light filtered by the ozone layer that is most harmful to human DNA.
Dobson Unit (DU) is the standard unit used to measure the total amount of ozone in the atmosphere.
The 'Ozone Hole' is a severe thinning of the layer, most prominently observed over Antarctica.
Option A is incorrect because ozone depletion is atmospheric, not a direct cause of water pollution.
Option C and D are incorrect because UV radiation generally damages plant chlorophyll and inhibits growth.
B is correct тАФ It protects us from harmful radiation.
Link this to Chemistry (CFC chemical properties) and Current Affairs (International environmental summits like COP meetings and Montreal Protocol amendments).
