CO2 Removal by Our Lungs
CO2 (Carbon dioxide) is an invisible gas that is naturally found in the atmosphere. It is one of the most important greenhouse gases and is produced by the burning of fossil fuels and other industrial activities. Humans and other animals exhale CO2 during respiration, and plants use it in photosynthesis to produce oxygen. Our lungs play an important role in the removal of CO2 from the atmosphere.
Respiration is the process of exchanging oxygen and carbon dioxide in the body. During inhalation, oxygen enters the lungs and is absorbed into the bloodstream, while carbon dioxide is released into the air. During exhalation, the opposite happens and the carbon dioxide is expelled from the body. The average person exhales about 2.3 pounds (1.0 kg) of CO2 per day.
Photosynthesis is the process by which plants use light energy to convert carbon dioxide into carbohydrates. The carbohydrates are then used to produce energy for the plant. During the process, oxygen is also released into the atmosphere. This process is responsible for removing more than 100 billion tons of CO2 from the atmosphere every year.
Our lungs play an important role in the removal of CO2 from the atmosphere. Every day, we exhale about 2.3 pounds (1.0 kg) of CO2. Additionally, plants use photosynthesis to absorb even more CO2 from the atmosphere. Together, these processes help to maintain a balance between the amount of CO2 in the atmosphere and the amount that is removed.
