Is your home "GREEN" enough?

This is the topic I chosen as my today's Toastmaster speech. I found useful information from National Geographic Magazine - "Green" House. This is an interesting subject talking about how you can do to improve your home environment. To make my speech persuasive, I use another stunning photo found from Wikipedia. You can find a "gherkin" like skyscraper with outstanding designs to let the building have better harmony with our Mother Nature. I like the building and the concepts behind it. I hope there are more and more new buildings can adopt the eco-friendly design guideline into considerations. WE ONLY HAVE ONE EARTH. Help me, also help you, to establish a better life in our future.
