Are you a Green collar worker?

In the true spirit of World Earth day, we need to think both at personal and professional front, how and what are we doing to save our environment. Green Jobs is one of the hot keywords of this time!
First of all, what does a Green collar worker mean; someone who does a "Green Job" for leaving. A green job can be anything which has a net positive impact (improvement) on our environment. It can be engineering job that is developing complex systems to make our roads and transportation smarter so that less fuels are wasted on road, or making intelligent global utility network to smartly distribute power to masses. It can be thousands of other types of jobs in the area of renewable energy development and distribution and many other professions which are evolving but not matured yet. Take a look at the Green Jobs Network Portal, where you can browse by Job Category or Locations. California is forefront of Green Energy development and leading the country in producing Green Jobs. 
Guess, demise of manufacturing jobs from America is going to replace the entire Blue Collar worker class to a whole new worker class called "Green Collar" and those workers will be proud of their net impact on environment. Happy Earth Day !!
