Deforestation contributes to global warming because it:

  1. Increases the albedo effect.
  2. Reduces the amount of Carbon dioxide removed by photosynthesis.
  3. Increases the oxygen concentration in the air.
  4. Decreases the amount of methane in the atmosphere.

📝 Detailed explanation

Trees act as carbon sinks; removing them means more CO₂ stays in the atmosphere to trap heat.
