a. Destroying rain forest trees would cause carbon dioxide levels in the atmosphere to drop dangerously low.
b. A loss of rain forest trees would have only a small effect on the carbon cycle, because they are green all year long.
c. Rain forest destruction would cause only a small increase in carbon dioxide levels if the roots were left to remove carbon dioxide from the air.
d. Cutting down rain forests could increase atmospheric carbon dioxide levels, because trees that could take up carbon dioxide would be removed.
