Question

what are the various sources of carbon dioxide?
​

Answer 1

• Carbon dioxide emissions originate from both natural and anthropogenic sources.
• Decomposition, ocean discharge, and breathing are all examples of natural sources.
• Cement manufacture, deforestation, and the combustion of fossil fuels such as coal, oil, and natural gas are all examples of human-made sources.
• Since the Industrial Revolution, the amount of carbon dioxide in the atmosphere has increased dramatically as a result of human activity, reaching dangerous levels not seen in the past 3 million years.
• 3 1 Although human-caused carbon dioxide emissions are significantly less than natural emissions, they have thrown off a natural equilibrium that had prevailed for thousands of years prior to human impact.
• This is due to the fact that natural sinks remove roughly the same amount of CO2 from the atmosphere as natural sources create.
• 4 This had maintained CO2 levels in check and below acceptable limits.
