A recent article in the New York Times should send chills down the spine of CEOs everywhere. The Times reports that in recent tests, Boston company Rapid7 found that a number of business teleconferencing systems are highly vulnerable to hackers, who could exploit security holes to eavesdrop on company meetings, many containing classified information. With cyber-war and virtual espionage beginning to be seen as legitimate security threats, businesses should definitely be concerned about security holes, and online security experts should have little trouble finding work in the years ahead.Yet beneath all the worry about security is some good news: Teleconferencing has become a commonplace feature of the modern work environment. This is not just good news for CEOs looking to cut costs, the greens should be rejoicing at this development as well. Prior to the teleconference, large companies were often forced to gather their spread-out staff in one central location for important meetings. These trips often involved long flights, which—as any green knows—burn up a healthy share of fossil fuels. Virtual conferences have allowed businesses to replicate these meetings at a fraction of the cost, and a fraction of the environmental impact as well.Hint for young greens: flee the NGO world like the plague. There is almost nothing here for you — or for the planet. Instead, get into tech and work on software and hardware that make teleconferencing and telecommuting more attractive to business. Instead of starving as your meager Greenpeace paychecks go to pay off your student loans, and toiling long years to achieve — well, in most cases, very little — you will get rich and do more for Gaia than all the sustainability campaigners at all the universities in the land.
