Where Is Wood Found?

Wood is found growing in deciduous and coniferous trees throughout the world, according to the Royal Forestry Society. The Forestry and Agriculture Organization of the United Nations explains that there are more than 4 billion hectares of forest on Earth as of late 2010, or approximately 31 percent of the world's land area. North Carolina State University's Cooperative Extension reveals more than 5,000 products are made from trees.

Approximately 5.2 million hectares of forests were lost annually between 2000 and 2010, an area roughly the size of Costa Rica. Around 12 percent of the world's forests, or more than 460 million hectares, are designated for conservation purposes, according to the FAO. The United States has the largest area of forests set aside for conservation at 75 million hectares as of 2010.

Every year, a single person uses paper and wood products that equal a 100-foot tree, 18 inches in diameter. One tree supplies one day's supply of oxygen for four people. Roundwood used for fuel comprises 1.87 million cubic meters of human wood consumption worldwide as of 2012, according to the FAO. Paper and paperboard products accounted for approximately 400 million tons of wood products in 2012. Wood exports were valued at $231 billion in 2012, a 7 percent decrease from the previous year.
