Describe at least two ways in which forests serve as an important resource for mankind.

1. Supply of wood:

The forests are made up of large amounts of trees, which, with regulated cutting, can continue to supply humans with wood needed for construction, fire-wood, ship-building (or at least before in history), and others.

2. Photosynthesis
