Background Paragraph: When humans dig up and use fossil fuels, we have an impact on the carbon cycle ( Figure below ). This carbon is not recycled until it is used by humans. The burning of fossil fuels releases more carbon dioxide into the atmosphere than is used by photosynthesis. So, there is more carbon dioxide entering the atmosphere than is coming out of it. Carbon dioxide is known as a greenhouse gas , since it lets in light energy but does not let heat escape, much like the panes of a greenhouse. The increase of greenhouse gasses in the atmosphere is contributing to a global rise in Earth’s temperature, known as global warming or global climate change. 
Story: Two villages were focused mostly on mining operation. Brown village extracted fossil fuels such as coal from their mountains, while Yellow village was mostly focused on extracting gold the old fashioned way.
Which village has less of an impact on Earth's temperature? Which village has less of an impact on global climate change? Which village has less of an impact on greenhouse gas levels? Which village has less of an impact on photosynthesis? Which village has less of an impact on the carbon cycle? Which village has more of an impact on Earth's temperature? Which village has more of an impact on global climate change? Which village has more of an impact on greenhouse gas levels? Which village has more of an impact on photosynthesis? Which village has more of an impact on the carbon cycle?
