The correct answer is Burning of wood

Key Points

  • Burning of wood is considered more environmentally friendly compared to burning charcoal, diesel, or coal.
  • Wood is a renewable resource and its burning can be carbon-neutral if harvested sustainably.
  • Unlike fossil fuels, burning wood releases the carbon dioxide that was absorbed by the tree during its growth, creating a balanced carbon cycle.
  • Charcoal, diesel, and coal are derived from fossil fuels which release a higher amount of greenhouse gases and other pollutants when burned.

Additional Information

  • Charcoal is produced by burning wood in the absence of oxygen, which makes it less efficient and more polluting than burning wood directly.
  • Diesel combustion releases nitrogen oxides and particulate matter, contributing to air pollution and health issues.
  • Coal burning is a major source of carbon dioxide emissions and other pollutants such as sulfur dioxide, contributing significantly to global warming and acid rain.
  • Adopting sustainable practices such as afforestation and using clean energy sources can further enhance environmental benefits.
