Which releases more CO2 into the ozone layer, burning coal or burping cows?
Most of the increase in carbon dioxide comes from burning of fossil fuels such as oil, coal and natural gas for energy, and from deforestation. Cows, sheep and other ruminant animals ‘burp’ methane into the air. Rice paddies also generate methane. Other sources of methane are landfills, burning vegetation, coal mines and natural gas fields. Cow manure and pig manure can be used (and is in some instances) to produce methane gas which is burned and used to produce electricy.
