MCQ

Which human activity has added them carbon to the atmosphere$?$

A
Mining of fossil fuels.
B
Increasing soil erosion.
✓
Burning fossil fuels.
D
Cutting down the rain forests.

✓

Answer

Correct option: C.

Burning fossil fuels.

Burning carbon requires oxygen $(O_2)$, and when we burn an atom of carbon, the required oxygen becomes part of the $CO_2$ molecule. So if the $CO_2$ increase is caused by burning carbon (fossil fuels) we would expect atmospheric $O_2$ levels to decrease at the same rate.
