奎因说：“从目前到2050年期间地球上会新增20亿人口，大家要怎么样养活这类人口？”

Darren Drewry is a scientist at the American Space Agency, NASA. He led a study of soybeans which NASA calls the world's most important protein crop. He says researchers using a computer were surprised to find that they were able to create a soybean plant that can be both more productive and use less water.
达伦•德鲁里（Darren Drewry）是美国宇航局的一位科学家。他领导了一项大豆研究，美国宇航局称大豆是世界上非常重要的蛋白质作物。他说，用电脑的研究职员惊奇地发现，他们可以开发一种生产率更高，更节水的大豆作物。

We find that there are changes to the architecture of modern soybean cultivars can be made to help us improve on many of these goals, said Drewry.
德鲁里说：“大家发现，现代大豆品种的体系结构可以改造，以帮助大家改变不少目的需要。”

Researchers were able to increase soybean productivity by 7 percent without using more water. The computer helped researchers do work that would have taken many years in the field. The next step is to test the computer's design.
研究职员可以在不需要更多水的首要条件下，将大豆生产率提升7%。计算机帮助研究职员完成了不少在地里需要不少年才能完成的工作。下一步的工作是测试这项计算机设计。

We spoke to Stephen Long about that. He is a professor at the University of Illinois, and one of the writers of the report on the soybean study. He told us by Skype that researchers used computer program to study what would happen if they changed the way the plant grows.
大家就此采访了史蒂芬•隆恩（Stephen Long）。他是伊利诺伊大学的一位教授，也是这项大豆研究报告的作者之一。他通过Skype告诉大家，研究职员用电脑程序研究了假如他们改变了这种作物的成长方法会发生什么变化。

One of the things the modeling predicted is that there's too much leaf area so we're actually removing leaves as the plant's growing to get a lower leaf area. We're also artificially modifying the angle of the leaves as well to reflect what the model predicted, said Long.
隆恩说：“电脑模型的预测之一是叶子太多，因此大家在作物成长时去除去一些叶子以降低叶子面积。大家还依据电脑模型的预测，人为地改变了叶子的角度。”

Professor Long says it is important to find solutions to the predicted global food shortage before it happens. He says it will be 20 years before farmers can begin growing a more productive soybean once they have developed it.
隆恩教授表示，在预计的全球粮食短缺发生前找到解决方法尤为重要。他说，一旦他们开发出来，农民开始种植这种生产力更高的大豆至少还需20年。

The study on soybeans was published in the journal Global Change Biology. The National Science Foundation, NASA and the Bill Melinda Gates Foundation paid for the study.
这项关于大豆的研究发表在《全球变化生物学》杂志上。美国国家科学基金会、美国宇航局与比尔和梅琳达•盖茨基金会为这项研究提供了资金。
