Answer:
Burning of fossil fuels
Explanation:
Over the last 200 years, burning of fossil fuels has been the major source of carbon emission.

It is now no surprise that carbon concentrations in the atmosphere is responsible for the environmental changes and that fossil fuel burning is the reason behind increased atmospheric carbon concentrations as proven by scientific research.
