GREEN: Trend or Lifestyle?

So, it's become inevitable that 'going green' and eco-friendly purchasing have become what's called a trend. However, I'm curious. How knowledgeable are people when it comes to eco-purchasing/eco-living? I mean, I know (just from the little research that I've been doing) that 'green' is all over the internet, and that there's a green alternative for just about everything--from eating to shopping to exercising and sleeping. And, it's great! But I'm interested in finding out whether it's a trend that is still generating interest and purchasing power from documentaries like An Inconvinient Truth, or if it's subcontiously becoming the preferred way to live. (I'm hoping it's the latter; however, I'll be keeping ya posted.)

Personally, as of right now, I feel that green living is still at the interest stage. I think people are looking to bigger corporations to see if and how they are adapting. Furthermore, I've started some inital browsing on this topic and I came across a book titled Thepurplebook (green edition). Thepurplebook is dedicated to highlighting the best websites for online shopping--meaning the best products for your dollar..etc, but in the case of the fourth edition (the green edition), the best 'green' products for your buck.

To read an interview with co-author, Ian Anderson, click here.

Although this book doesn't quite begin to answer my questions on whether 'green' is more of a trend that exists more on the internet than an actual lifestyle..it actually kind of does. First of all, the fact that it is discussed on the internet AND, at the same time, is in print. And, second..the interview that I've linked discusses how this book is not only targeted toward people who already buy green, but anyone interested. Anyways, these are just my current thoughts.

..Completely ridiculous topic? Good? Any suggestions?
