Carbon dioxide levels in the atmosphere can be reduced by reducing the amount of fossil fuels burned. This can be done by switching to renewable energy sources such as solar, wind, and hydroelectric power. Additionally, reducing the amount of deforestation and increasing the amount of reforestation can help reduce carbon dioxide levels. Planting trees and other vegetation helps absorb carbon dioxide from the atmosphere. Finally, reducing the amount of meat and dairy products consumed can help reduce carbon dioxide levels, as the production of these products is a major source of emissions.
