CO2 Carbon dioxide

Carbon dioxide, or CO2, is a colorless, odorless gas that is essential for life on Earth. It plays a crucial role in the carbon cycle, serving as a primary source of carbon for photosynthetic organisms like plants. CO2 is also used in a variety of industrial processes, such as the production of carbonated beverages and dry ice. However, high levels of CO2 in the atmosphere can contribute to global climate change, as it is a greenhouse gas that traps heat in the Earth's atmosphere. As such, efforts are being made to reduce CO2 emissions and develop alternative, sustainable energy sources that do not release CO2 into the atmosphere.
