What is the long-term effect of cutting down larger areas of rain forests?

ADecreased carbon dioxide content in the air
BDecreased flooding of low-lying land
CIncreased rainfall in these areas
DIncreased rate of soil erosion ✓ Correct
Correct answer: (D) Increased rate of soil erosion
Explanation

Clearing large areas of rain forest leads in the long term to an increased rate of soil erosion, as bare ground is left exposed to heavy rain.

Carbon dioxide in the air would rise, not fall, because fewer trees absorb less of it.

Low lying land tends to flood more, not less, once forests no longer soak up and slow the runoff.

Rainfall generally decreases rather than increases when the forest that recycles moisture is removed.

Tree roots normally hold the soil together and the canopy softens the impact of falling rain.

With both gone, fertile topsoil is stripped away and washed into rivers, silting them up.
