Carbon dioxide (CO2)
Carbon dioxide (CO2) is a colorless gas that is a natural part of Earth's atmosphere. It is produced when living organisms breathe, when things burn, and from certain industrial processes. CO2 is important for plant life, as they use it during photosynthesis to make food. However, elevated levels of carbon dioxide contribute to climate change by trapping heat in the atmosphere, leading to global warming. This process disrupts weather patterns and ecosystems. Balancing CO2 levels is essential for maintaining a healthy environment and ensuring life on Earth continues to thrive.
