Wood is the one product quickest to come to mind.
People have used wood to make tools and construct buildings as well as for forms of art and expression. Wood has also been used as a source of fuel. Trees are also important to people in that they keep soil from eroding into rivers, lakes and oceans, and they provide enormous amounts of oxygen through photosynthesis, while consuming carbon dioxide. Wood products are made from the millions of trees cut down in the world's forests. Sawmills cut the logs into usable lumber, which is then used in the construction, furniture, and paper making industries.
