Global warming is a serious environmental problem where Earth's average temperature slowly rises. This mainly happens because greenhouse gasses build up in the atmosphere. Greenhouse gasses, like carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) trap heat from the sun, creating the "greenhouse effect."
This effect is natural and helps keep Earth's temperature stable. But human activities have made it much stronger, causing too much warming. The main sources of these extra greenhouse gasses are human actions, such as burning fossil fuels for energy, cutting down forests, and various industrial activities. Fossil fuels like coal, oil, and natural gas release a lot of CO2 when burned for electricity, transportation, and heating. Cutting down forests, especially in tropical areas, not only releases the CO2 stored in trees but also reduces the number of trees that can absorb CO2, making the problem worse.
Industrial activities like producing cement and certain farming practices release a lot of methane and nitrous oxide, which also increase the greenhouse effect.
