一项日前发表于《生物学快报》的研究表明,全球变暖会很快威胁到包括小麦、水稻等主要食物在内的禾本科植物。目前,小麦和水稻为人类提供了所消耗全部卡路里的一半。这项展望至2070年的最新研究发现,气候变化发生的速度要比禾本科植物的适应能力快上千倍。虽然研究并未预测全球粮食供应可能会因此出现何种状况,但论文作者警告说,“后果 A recent study published in the Biology Letters shows that global warming can quickly threaten grasses including staple foods such as wheat and rice. Currently, wheat and rice provide humans half the total calories they consume. The latest study, which looks to 2070, has found that climate change occurs thousands of times faster than grasses can adapt. Although the study did not predict what could happen with the global food supply, the authors warn that ”the consequences
