The correct option is A Global warming and ozone depletion


Global warming and ozone depletion

1. The two major environmental issues of global nature are global warming and ozone depletion since it is irreversible and has very harmful effects on humans across the globe.
2. Global warming, characterised by increase in the temperature of the Earth’s atmosphere, can lead to the melting of the polar ice caps and rising sea levels that can cause submerging of many coastal places.
3. Ozone depletion in the stratosphere can cause exposure to direct UV radiation that can lead to skin cancer, cornea damage etc.

Final answer

(C) Global warming and ozone depletion
