Eco-friendly or unfriendly

Now, when bamboo can be made into bicycles and into notebooks (Asus Eco Book), it's really telling us that we are going back to the very natural and raw materials for many products, even eletronics. As ethanol is already causing food prices to increase, I begin to wonder what the impact will be - on natural and raw materials. While we say "Go-Green", are we really preserving the environment ? It seems a vicious cycle to me. They are even talking about algae and plankton for chip nanofabrication. Well, I just hope it's not the case of protecting the environment by destroying more nature. :O How ironical...
