Which of the following statements about the world's forests are correct?

1.Forests act as a huge carbon sink

2.Most of the world's forests are concentrated in the subtropical belt in the northern and southern hemispheres

3.Forests are home to much of the world's biodiversity

4.Moisture released from forests also contributes to rainfall

A1 and 2 only

B2, 3 and 4 only

C1, 3 and 4 only ✓ Correct

D1, 2 and 3 only

Correct answer: (C) 1, 3 and 4 only

Explanation

Forests act as carbon sinks, harbour vast biodiversity and add moisture that returns as rainfall.

Statement 1 is right because forests absorb and store large amounts of atmospheric carbon.

Statement 3 is right because forests hold much of the planet's terrestrial biodiversity.

Statement 4 is right because evapotranspiration from forests feeds regional rainfall.

Statement 2 is wrong because most forests lie in tropical and boreal belts, not the subtropics.

Losing forests weakens all three of these vital functions at once.
