The primary cause of global warming is the increased concentration of greenhouse gases in the Earth's atmosphere. These gases, including carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), trap heat from the sun and prevent it from escaping back into space. This phenomenon is commonly referred to as the greenhouse effect. The main contributors to the increase in greenhouse gases are human activities, particularly the burning of fossil fuels such as coal, oil, and natural gas for energy production, transportation, and industrial processes. When these fuels are burned, they release significant amounts of CO2 into the atmosphere. Deforestation and land-use changes also play a role by reducing the Earth's capacity to absorb CO2 through photosynthesis. Other human activities, such as agriculture (especially livestock production), industrial processes, and waste management, contribute to the emissions of methane and nitrous oxide, which are even more potent greenhouse gas...
