In reality, printing is a sustainable industry that actually benefits the environment. Let's debunk a few of the myths surrounding printing... and discover why it's greener than you think.
Myth #1: The Number of Trees in the U.S. is Declining
Actually, the opposite is true. Statistics from the Food and Agriculture Organization indicate that forest growth has exceeded harvest for more than 60 years; in fact, forest growth volume is 380 percent more today than it was in the 1920s. That means that the country is actually home to 20 percent more trees today than on the first Earth Day in 1970.
What's behind this growth? A few factors, including:
- Expansion of national parks
- Population shift from rural to urban areas
- Sustainable tree farming
Number three is especially significant for the printing industry. Every day, those who privately own and manage forests, tree farms, and tree plantations plant about 4 million trees -- or three times as many as they harvest.
Myth #2: Printing Kills Forests
Only about 11 percent of harvested trees are used to make paper (while 53 percent are used for fuel and 28 percent for lumber), so that "think before you print and save a tree" saying isn't accurate.
In fact, printing actually contributes to the increasing number of trees. How? When there's a healthy market for sustainably grown trees, landowners are much more likely to continue using their land to grow and maintain forests, rather than sell land off to developers. The more land that's used for sustainable tree farming, the less pressure there is on primary forests to produce wood fiber.
Myth #3: Going Digital is Better for the Earth
As it turns out, not so much. Do you know what materials are used to manufacture those iPads, smart phones, e-readers, and laptops? Let's compare e-readers and books.
Materials: An e-reader requires extraction of 33 pounds of minerals and 79 gallons of water; a book requires two-thirds of a pound of minerals and 2 gallons of water to produce.
Manufacturing: Making an e-reader requires a heavy energy input of about 100 kilowatt hours of fossil fuels and produces 66 pounds of carbon dioxide; a book requires 2 kilowatt hours and produces about a pound of CO2.
Health Impact: The adverse effects on human health -- such as toxic emissions -- of making an e-reader are 70 times higher than that of making a book.
Disposal: E-readers contain toxins that can leach into ground water if not properly recycled; a non-recycled book decomposes in a landfill, generating about twice as many emissions as the manufacturing process.
A few other facts to consider: In the U.S., more than half the energy expended on paper manufacturing comes from renewable resources, and printing is a one-time input of energy. Digital devices, on the other hand, require constant energy. Plus, Americans generate more than 13 million tons of e-waste per year. Overall, the environmental impact of one e-reader is equivalent to about 100 books, according to the New York Times.
Given the numbers, it's easy to understand how printing contributes to a greener Earth.
