Question 29 • Biology

How will the level of carbon in the atmosphere change if humans do nothing to reduce their impact on the carbon cycle?

Answer
A
Carbon will be removed from the atmosphere altogether.
B
The level of carbon in the atmosphere will decrease.
C
Carbon in the atmosphere will remain the same.
D
The level of carbon in the atmosphere will increase.

Explanation

Human activities such as burning fossil fuels release carbon dioxide into the atmosphere. If people do nothing to reduce their impact on the carbon cycle, these emissions will continue to add carbon faster than natural processes can remove it, so the atmospheric carbon level will increase. The correct choice is “The level of carbon in the atmosphere will increase.”
