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
The forests use Photosynthesis to take in carbon dioxide & monoxide (created by us humans), and with the process of photosynthesis, release Oxygen as it's waste (which we humans use).
Forests serve as a resource in many different ways, but one very important function it serves is fuel. Wood from trees serves as an important energy source for many because it can be burned to heat homes when it’s cold or to prepare food. Forests also serve many functions in modern industry. Logging is a big business that provides lumber for the manufacturing of furniture and paper products, as well as home and building construction. Forests provide an important service for our atmosphere, by producing oxygen and removing CO2. They also serve as a habitat for many species.

The breaking rocks allow the overriding plate to slip over part of the subducting plate all along the fault line. The plate movement on the ocean floor can cause a tsunami.
