If the roughly 250 million households (about 1 billion people) of the industrialized nations were to adopt low-carbon lifestyles-switching from two conventional automobiles to one gas-electric hybrid, utilizing heat pumps to assist indoor climate control and water heating, and making eight short-distance annual leisure trips rather than eight long-distance ones-it would reduce annual global carbon emissions by 2 billion tons, increasing our chance of survival by nearly one-third.
以全球工業化國家 10 億人口（2.5 億個家庭）計，若每個家庭都選擇低碳生活──二輛房車換成一輛油電車，冷暖氣系統、溫水泳池換成地上熱力幫浦；每年 8 次長程旅行改為 8 次短程旅行等，則一年可減少 20 億噸碳排放，相當於增加 1/3 的救命機會。
