Each
of earth's 6 billion inhabitants uses abut 4 pounds of wood daily.
Americans use about
Our Daily Wood
Every
day, each of Earth’s 6 billion inhabitants uses this much wood – about four
pounds on average. But the average American uses 3.5 times as much. Should
America use less wood? Steel, aluminum and concrete are touted as substitutes
whose use will help “save forests.” But wood is the only resource on Earth
that is renewable, recyclable and biodegradable. What’s more, the only energy
needed to grow wood fiber is the free, non-polluting energy of the sun. Most of
the energy consumed in the manufacture of steel, aluminum and concrete comes
from fossil fuel – petroleum. And when fossil fuel burns, it releases carbon
dioxide, the compound most often linked to global warming. But growing trees
remove carbon dioxide from the atmosphere, adding oxygen to the air we breathe.
Moreover, about half the dry weight of wood is carbon - meaning that the carbon
dioxide trees absorb from the atmosphere becomes part of the wood we use. The
formula describing this miraculous exchange is beautiful in its simplicity: to
produce one pound of wood, a tree takes in
1.47 pounds of carbon dioxide and returns 1.07 pounds of oxygen to the air we
breathe. As our civilization searches for ways to contain its insatiable
appetite for Earth’s raw materials, these questions beg for answers: Where
will we get our daily wood and why are we unnecessarily using products that
pollute the air we breathe?
