The main greenhouse gas released by human activities is carbon dioxide (CO2). This gas is primarily produced through the burning of fossil fuels, deforestation, and various industrial processes. CO2 traps heat in the atmosphere, leading to the greenhouse effect, which contributes to global warming and climate change. Its increased concentration is associated with numerous environmental issues, such as rising sea levels and changing weather patterns. Efforts to reduce CO2 emissions are critical for mitigating the impacts of climate change on ecosystems and human societies.
