Detailed explanation-1: -Also, fossil fuels, when burned, produce large quantities of carbon dioxide. This will also increase global warming. Thus reducing deforestation and cutting down the use of fossil fuels will decrease global warming. Thus the correct answer is Reducing deforestation, cutting down the use of fossil fuel, option (D).
Detailed explanation-2: -Fossil fuels – coal, oil and gas – are by far the largest contributor to global climate change, accounting for over 75 per cent of global greenhouse gas emissions and nearly 90 per cent of all carbon dioxide emissions. As greenhouse gas emissions blanket the Earth, they trap the sun’s heat.
Detailed explanation-3: -When deforestation occurs, much of the carbon stored by trees is released back into the atmosphere as carbon dioxide, which contributes to climate change.
