Question

How have human activities increased atmospheric carbon dioxide levels?

Answer 1

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.
