Question

Which among the following are the consequences of ozone depletion?
A. The entry of UV-rays into the earth’s atmosphere
B. Various skin troubles like skin cancer.
C. Cataract
D. All of the above

Answer 1

The lower stratosphere layer comprises a layer that involves a high concentration of ozone. This layer is called the ozone layer. The ozone layer is responsible for preventing the entry of harmful ultraviolet rays into the Earth's surface. The process which involves the thinning of the ozone layer of the earth due to industry generated gas(CFCs) is called depletion of ozone. The depletion of the ozone layer is maximum in the polar regions of the earth.

Complete answer:

Depletion of ozone can leads to many consequences which are given below:
Due to the thinning of the ozone layer an excess amount of ultraviolet rays start to come from the sun. > Harmful ultraviolet rays are responsible for causing several health issues in humans as well as other animals and plants.
The excessive entry of ultraviolet rays can cause skin disease that may lead to skin cancer.
UV rays can lead to genetic disorders by the mutation.
Eyes are a very sensitive organ that can be affected by ultraviolet rays and result in eye cataracts.
Several immunological disorders can be caused by exposure to ultraviolet rays.

So, the correct answer is option D.

Note: Depletion of the ozone layer can be prevented by taking some steps like minimization of the use of those compounds in the industries that are responsible for generating toxic gases like CFCs, minimization of car use to control pollution, decrease of the use of those cleaning agent that can generate toxicity, reduction in the use of air conditioner as it exits out CFCs in the environment.
