Question

which action would most reduce carbon dioxide levels in the atmosphere?
expanding forests
burning more coal
removing wetlands
increasing livestock farming

Explanation:

To determine which action reduces atmospheric CO₂, we analyze each option:

• Expanding forests: Trees absorb CO₂ via photosynthesis, so this reduces CO₂.
• Burning more coal: Releases CO₂, increasing levels.
• Removing wetlands: Wetlands store carbon; removal would release it, increasing CO₂.
• Increasing livestock farming: Livestock (like cows) produce methane and related processes can increase CO₂/ greenhouse gases.

So expanding forests is the correct action.

Answer:

A. Expanding forests
