Question

Which of the following is/are responsible for the alarming rate of environmental degradation?

• A. Ozone layer depletion
• B. Greenhouse effect
• C. Global warming
• D. All of these

Answer 1

The correct option is D

All of these

As the levels of harmful substances are increasing exponentially, the entire world is facing problems like global warming, enhanced greenhouse effect etc.

Global warming is a gradual increase in the average temperature of the earth's atmosphere and its oceans, a change that is believed to be permanently changing the earth’s climate. Ozone layer depletion is caused due to damage in stratospheric ozone by CFCs and HCFCs used as refrigerants, aerosols and propellants. This prevents the blocking of harmful UV radiations.
