Environmental Science

Matching the environmental impacts with their corresponding pollutants:

1) Nitrogen rich fertilizers - q) Eutrophication: Excess nitrogen causes algal blooms and oxygen depletion in water bodies.

2) Carbon dioxide - r) Greenhouse effect: CO₂ is the primary gas responsible for global warming.

3) Carbon monoxide - s) Air pollutant: CO is a toxic gas that reduces blood's oxygen-carrying capacity.

4) CFC's - p) Ozone depletion: Chlorofluorocarbons destroy stratospheric ozone molecules.

The correct matching is: (B) 1-q, 2-r, 3-s, 4-p

Other options are incorrect because: - (A) Incorrectly links fertilizers with ozone - (C) Mismatches all relationships - (D) Reverses several cause-effect pairs
