Trees are nature’s factories. They take simple ingredients like water, carbon, oxygen and nitrogen and turn them into complex molecules like cellulose fibers.

In fact, cellulose fibers are one of the world’s most useful and abundant natural materials. They are the main component of cell walls in most plants, and they give wood its strength and resilience. Essentially chains of linked sugar molecules, cellulose fibers are used in a variety of products — including textiles, paper and diapers — because of their strength, durability and ability to absorb and transport water.
