  • 第21题:

    问答题
    Water is vital for our survival and for producing food. It takes about a thousand tons of water to produce one tone of grain that, fed to cows, produces only 18 pounds of meat. Today mankind is using about 160 billion tons more water each year than is being replenished by rain and fed back into water storages. If this water were carried in water trucks, it would require a 300, 000-mile-long convoy of trucks every day—a convoy length 37 times the diameter of the Earth. This is how much water we are using and not replenishing.

    正确答案:
    水是人类生存之所系,是食物生产之所需。生产一吨谷物需要耗费一千吨的水,而用一吨的谷物喂牛的话,只能为我们换取18磅的牛肉。如果将使用的水和下雨后蓄存的水相比较,那么人类可以说是入不敷出,每年大概多用了1600多亿吨水。如果用水车载水,那每天就得有一个30万英里长的车队,而这个车队的长度将是地球直径的37倍。这就是我们正在使用的水量,而不是正在获取的水量。
