How does composting reduce greenhouse gases?

Answer: Prevents methane from landfills

Prevents methane from landfills ✓ — Correct! Organic waste in landfills decomposes without oxygen, producing methane—a greenhouse gas 25x more potent than CO₂. Composting decomposes waste with oxygen, producing CO₂ instead while creating nutrient-rich soil.

Worms clean the soil naturally — Wrong. Worms help decompose matter, but the main environmental benefit is diverting waste from landfills where it would produce methane, a powerful greenhouse gas.

Saves water for farmers — Wrong. Composting doesn't directly save water. It helps by reducing landfill methane emissions and creating soil amendment that improves soil health.
