粮价
中午偶然瞟了一眼CCAV2，财经观察正在播一个国际粮食危机的节目，不看不知道，一看吓一跳，由于急剧上涨的粮价，原来现在都有三十多个国家闹危机了。非洲，泰国，阿根廷…………
我们这的大米价格也在涨，但还也不致到那些国家那么夸张的程度。
上网查了一下，google news的结果，国际粮食危机(. com)
wikipedia 有一个页面专门讲此次粮食危机：2007–2008 world food price crisis
什么因素造成了如此严重的危机呢，各方还在争论之中，我一毫无专业背景的闲人那就更不知道了，我看那节目倒是花了很大的篇幅讲发达国家（尤其是美国）把大量的玉米啊之类的粮食拿出提取乙醇，用来做生物燃料，言之凿凿的样子……
wiki给出的因素有着一些（应该也是各方观点的集合）
Initial causes of the late 2006 price spikes included unseasonable droughts in grain producing nations and rising oil prices. Oil prices further heightened the costs of fertilizers, food transport, and industrial agriculture. Other causes may be the increasing use of biofuels in developed countries (see also food vs fuel),[1] and an increasing demand for a more varied diet (especially meat) across the expanding middle-class populations of Asia.[2][3] These factors, coupled with falling world food stockpiles have all contributed to the dramatic world-wide rise in food prices.[4] Long-term causes remain a topic of debate. These may include structural changes in trade and agricultural production, agricultural price supports and subsidies in developed nations, diversions of food commodities to high input foods and fuel, commodity market speculation, and climate change.
希望那些国家早日走出危机……希望非洲的人民不要再饿肚子，全世界的人都有饭吃……
嗯，我要节约粮食。
