Answers
Step-by-step explanation:
As greenhouse gas emissions blanket the Earth, they trap the sun’s heat. This leads to global warming and climate change. The world is now warming faster than at any point in recorded history.
Generating power
Generating electricity and heat by burning fossil fuels such as coal, oil, and natural gas causes a large chunk of global emissions. Most of the electricity is still produced from fossil fuels; only about a quarter comes from wind, solar, and other renewable sourc,
Manufacturing goods
Manufacturing and industry produce emissions, mostly from burning fossil fuels to produce energy for making things like cement, iron, steel, electronics, plastics, clothes, and other goods. Mining and other industrial processes also release gases.
Cutting down forests
Cutting down forests to create farms or pastures, or for other reasons, causes emissions because when trees are cut, they release the carbon they have been storing. Since forests absorb carbon dioxide, destroying them also limits nature’s ability to keep emissions out of the atmosphere.
