Answer:
Human various activities like burning fossils and huge land cover changes contribute to increasing the carbon dioxide of atmosphere.
Explanation:
- Carbon dioxide level in atmosphere is increasing naturally by organism respiration, decay, volcanoes erupt and carbonated rocks are weathered.
- Human activities like, urbanization, deforestation, vegetation pattern changes results in changes to reflectivity of earth surface and emmision through burning fossils fuels/forest and cement production are causining an increase in atmospheric carbon di oxide level. When fossils fuel burn the carbon combine with oxygen to form CO2.
- All these processes ultimately contribute to global warming.
