Why is wood being progressively replaced by LPG in many Indian households?
ABurning wood produces a lot of smoke (causing respiratory disease) and contributes to deforestation; LPG has much higher calorific value and burns cleaner
BLPG is cheaper than wood everywhere
CTrees release no useful products other than fuel
DWood has higher calorific value than LPG
Answer & Solution
Correct answer: A. Burning wood produces a lot of smoke (causing respiratory disease) and contributes to deforestation; LPG has much higher calorific value and burns cleaner
Wood burns smokily, releasing particulate matter that causes respiratory diseases — a major health concern in rural kitchens. Cutting trees for firewood causes deforestation. LPG has roughly three times the calorific value of wood (per gram), burns much cleaner, and is convenient. Cost varies by region, but the trend is clear.
