Carbon dioxide (CO2) is a colorless, odorless gas that is vital to life on Earth. It is a naturally occurring component of the Earth’s atmosphere, constituting about 0.04 percent by volume. CO2 is produced by the respiration of animals and plants, volcanic eruptions, and the combustion of organic materials and fossil fuels. It plays a critical role in the Earth’s carbon cycle and is a key greenhouse gas, trapping heat in the atmosphere and significantly influencing the planet’s climate. Additionally, carbon dioxide is utilized in various industrial processes, including the production of soft drinks, fire extinguishers, and as a solvent in chemical extractions. Its increasing concentration in the atmosphere is a major contributor to global warming and climate change, prompting widespread scientific and political efforts to reduce emissions.
