每日一句(63-24/09/09)：保护森林与减排

At the current rate of deforestation, around one-third of the forest in Amazonas will have been lost by 2050, releasing a colossal 3.5 billion tonnes of carbon dioxide into the atmosphere. (From The Economist, September 24, 2009: Last gasp for the forest)

以目前采伐森林的速度，到2050年大约1/3的亚马孙森林会消失，会有35亿吨之巨的二氧化碳释放到大气中。

2、colossal: (adj.) extremely large.
*a colossal statue
