Question

What do humans do to decrease carbon in geosphere and biosphere

Answer 1

Humans are increasingly burning fossil fuels, consequently there are more carbon dioxide emissions. In addition, we take part in deforestation (where trees are cut down), meaning once again CO2 levels increase.
Explanation:
Cutting down trees and overharvesting plants means less photosynthesis occurs, subsequently, less oxygen is being release and less Co2 levels are being absorbed. Overall, human activity causes more carbon emissions.
