Green Building????

So I am watching this show on how this house was built green. How the architect and the builders put the environment first. How they used "green" technology. It was all good and all worthwhile, however they missed a huge point. Is it " Green " to have big monstrous houses, which take more resources to build and sustain? How much weight should the green building put on the size of a home? If two people build a green house with 4500sq feet, is it really thinking green? No!!!!!!
I bet they watch "An inconvient truth" on their big plasma screens in each room in this green house. I bet there is prius in the three car garage!!!!
