How might the destruction of rainforests affect the balance of gases in Earth's atmosphere?
by increasing carbon dioxide and decreasing oxygen

Answer 1

by increasing carbon dioxide and decreasing oxygen

Reason: Cutting and burning trees releases CO2 and reduces the amount of photosynthesis (less CO2 uptake and less O2 production), so atmospheric CO2 rises while O2 production falls.
