Original Promptcreate a case study that has students examine human impact on the carbon cycle
This resource explores the significant disruptions to the carbon cycle caused by human activities, specifically deforestation and fossil fuel combustion. It begins by examining the natural state of the carbon cycle, where photosynthesis captures carbon dioxide and stores it in living biomass, followed by natural decomposition processes that return carbon to the soil and atmosphere. The lesson highlights how human-induced factors, particularly the burning of fossil fuels, release large amounts of previously sequestered carbon, leading to an overwhelming surplus of CO2 in the atmosphere. Deforestation is presented as a dual threat—it not only releases stored carbon but also eliminates the trees that would normally absorb future emissions, exacerbating climate change. Students will analyze data on global CO2 emissions over time, explore the mechanisms behind these disturbances, and reflect on local activities that contribute to carbon output.
