Final answer:Thehuman activitythat directly contributes toglobal warmingis the burning of fossil fuels.Explanation:Global warmingis primarily caused by the increase in greenhouse gases in the Earth's atmosphere. One of the main human activities that directly contributes to global warming is the burning of fossil fuels. When we burn coal, oil, and natural gas for energy, carbon dioxide (CO2) is released into the atmosphere. CO2 is a greenhouse gas that contributes to the greenhouse effect and global warming.In addition toburning fossil fuels, other human activities also contribute to global warming. Deforestation, which involves the clearing of forests for agriculture, urbanization, or logging, reduces the Earth's capacity to absorb CO2 through photosynthesis. This leads to an increase in CO2 levels in the atmosphere. Industrial processes, such as the production of cement and steel, release greenhouse gases like CO2 and methane (CH4). Agricultural practices, such as livestock farming and the use of synthetic fertilizers, also contribute to global warming through the release of methane and nitrous oxide (N2O).Overall, it is important for us to reduce our reliance on fossil fuels, promote sustainable land use practices, and adopt cleaner technologies to mitigate the impacts of human activities on global warming.Learn more abouthuman activity and global warminghere:brainly.com/question/29461017#SPJ14...
