但是，对于莱斯大学报告中所称，利用玉米生产乙醇燃料并非处处行得通这一点，布莱克表示同意。她也认为利用农业废料和其他纤维质作物生产乙醇言之有理。布莱克说：“利用纤维质作物生产乙醇的好处是它在全国各地都行得通。在适合玉米生长的地区，可以把部分玉米用来生产乙醇，但在国内其他地区，人们可以就地取材。”
The ethanol industry backs the use of the alcohol additive to gasoline as way of reducing petroleum consumption nationwide.
乙醇工业推动了酒精添加剂在汽油中的使用，在全国范围内降低了汽油的消费。
But Pedro Alvarez argues that it might be better for the environment as well as farmers to use the alternative fuel locally and not try to transport it long distances. He says that the growing world population might force policy changes not only in terms of water used for fuel crops, but also in terms of how water is used to produce the food we eat.
但是，阿尔瓦雷斯认为，更好的做法是就地取材生产替代燃料，以避免长途运输，这对农民和环境都有好处。他还说，全球人口增加将迫使各国不仅改变燃料作物的用水政策，也将改变粮食生产的用水政策。
"To make one kilogram of bread, let's say, you need 1,000 liters of water and to make one kilogram of meat you need 10,000 liters of water. The point here is that water is going to be a severe limiting factor - not only to economic development, but just to feed a growing population," he said.
“生产一公斤面包，比方说，需要用1000公升水；生产一公斤肉，需要用1万公升水。关键的问题是：水资源将变成一个严重的限制因素，不仅限制经济发展，而且会限制不断增长的人口的吃喝。”
Alvarez says population growth will drive the need to allocate water carefully for various food crops as well as livestock. Likewise, he says, it will be necessary to balance the goals of reducing oil consumption and supporting the income of farmers with the need to preserve the water that makes agriculture possible.
阿尔瓦雷斯说，人口增长会促使人们在粮食生产和家畜饲养方面更加小心地分配水资源。同样地，在减少石油消费、增加农民收入和确保水资源能够满足农业生产方面，的确有必要求得平衡。
