Green living How to do it?

I have recently found a conscious awareness to try and become a greener person.We all watch the news,see how climate change is effecting people all over the world.The Maldives government conducting a conference under water to explain what will happen if green house gases are not controlled.Wild life disappearing etc.
I found this great you tube clip about how to become greener.
It is about building a green sustainable house plus it does have some interesting items that could be put into any bodies home.
