Question

The gas released during anaerobic degradation of vegetation may lead to :

• A. Acid rain
• B. Global warming and cancer
• C. Corrosion of metals
• D. Ozone hole

Hint:

Methane is often called "marsh gas" because it is naturally produced in wetlands through the decay of organic matter in the absence of oxygen.

Answer 1

The Correct Option is B

Step 1: Anaerobic degradation of vegetation produces Methane ($CH_4$).
Step 2: Methane is a potent greenhouse gas that contributes significantly to Global Warming.
Step 3: High concentrations of such hydrocarbons in industrial/polluted contexts are also associated with carcinogenic risks.
