For alot more than two months when I've gone house from work, I'd flip on the evening news hoping to see the volcano of oil erupting from one mile beneath the Gulf of Mexico miraculously stilled, plugged somehow, staunching the amazing flow of oil and natural gas that is killing wildlife, devastating habitat and shutting down whole segments of Gulf-related organizations.
But rather than breathing a sigh of relief, night after night I'd sit mesmerized -a small queasy and apprehensive- watching the oil continuing to flow, developing what appears to be the greatest environmental calamity of my life -at least in this part of the world.
Like everyone else at property marveling at this spectacle revealed by BP's underwater camera, I am powerless to do anything to "just plug the damn hole," as our president reportedly said at a recent White Home meeting. Fortunately, BP's most recent attempt to cap the wellhead appears to be working, and there could be some finish to this phase of the environmental disaster in sight.
But regardless of what happens a mile below the sea, it is imperative to recognize that I'm not powerless in my personal and expert life when it comes to helping to guard the environment. That is why along with my decision to drive a fuel-efficient vehicle, recycle paper, glass and plastic and teach my children respect the environment in their day-to-day lives, I've decided to dedicate a couple of columns to digital signage as a "green" technology.
Typically, when the environmental impact of digital signage is raised, some valid, but rather nicely-worn, assertions are made. Initial, when compared to printed signs, digital signage appears far greener. Digital signage messaging, which can be updated or changed entirely with a few strokes of the keyboard and some mouse clicks, eliminates the have to have to print new signs as messaging requirements change. The fewer the signs that get printed, the fewer the trees that will need to be cut, transported to mills, processed and created into paper, the logic goes. The require for the inks utilised to print the signs and the many different chemical coatings applied to make them appealing is eliminated.
One more dimension, generally cited, is waste disposal. Cutting out the will need to replace printed signs eliminates the power needed to dispose of or recycle the signs and -to the degree printed signs aren't recycled- the impact of adding tons far more paper, ink, chemical coatings and paints to landfills.
A third frequently cited benefit is that the convenience of updating digital signage messaging over a pc network eliminates travel to the location of every sign, which is essential to replace printed old signs with new printed versions. Eliminating the transportation component reduces carbon emissions and therefore the impact of signage on the environment.
Even though each and every of these assertions argues in favor of the environmental benefit of making use of digital signage over conventional printed signs, that's not to say digital signs do not impact the environment and that a selection of actions can and should certainly be taken when probable to decrease the impact of this digital medium on our planet. In the second part of this column, I'll look at some of the leading environmental considerations regarding the use of digital signs and actions that can be taken to decrease their impact.
