冰天動地

Many people watched 冰天動地 on the past few weeks, however I wonder  how many of us would really concern the future of our earth and plan to do something to save our earth. Eg Buy fewer clothes, don't replace their mobile phones, DVD, TV etc unless necessary, waste less food especially when having buffet, try to avoid turning on the air-conditioner during summer (or at least adjust the the temperature a bit higher. However sometimes really wonder if most HK people really start to spend less, how many more people in HK will lose their jobs and how poor the economy will be.
