Outside of the home, most people spend the majority of their days in their workplaces.  That fact is what makes greening your office so important.  It's easy to become detached from a space that we do not own, thereby adopting a mentality of "no ownership equals no responsibility."  However, the onus is on each individual to work toward a greener earth, with the goal of reducing their carbon footprint.  So starting recycling programs in the office or buying greener supplies are environmentally friendly ways to do business.  And in addition, they can also be cost effective.
