Can carbon dioxide be used for anything?
Carbon dioxide is already being used in novel ways to create fuels, polymers, fertilisers, proteins, foams and building blocks. Until recently, it was assumed that energy-intensive firms burning gas to fuel their processes would need eventually to capture the resulting carbon emissions and bury them underground.
What does a low CO2 level mean?
A low CO2 level can be a sign of several conditions, including: Kidney disease. Diabetic ketoacidosis, which happens when your body’s blood acid level goes up because it doesn’t have enough insulin to digest sugars. Metabolic acidosis, which means your body makes too much acid.
