Establishing a human colony on the Moon and travelling to Mars has been the stuff of dreams since the dawn of the space age. 在月球上建个人类的殖民地，去火星旅行是人类自太空时代开启之初一直以来的梦想。 But these visions face many hurdles. How can humans survive for months or years in the ultra-hostile environment of space? What, for instance, will they eat? 但是这些愿景面临着许多阻碍。人们怎么才能在极端不利的太空环境下生存几个月甚至数年？举个例子来说，他们吃什么呢？ Agricultural researchers at a Dutch university say they are taking the first steps towards providing an answer. 荷兰一所大学的农业研究员说，为了找到答案，他们正在迈出第一步。 They are growing vegetables in soils similar to those found on the Moon and Mars, looking for ways of helping space pioneers grow their own crops. 他们在与月球和火星相似的土壤中种上蔬菜，试图寻找帮助太空开拓者自己种庄稼的方法。 "When people go to the Moon and Mars they also have to eat, and it's easiest for them to grow their own food," said Wieger Wamelink, surrounded by several dozen plants in a special greenhouse at Wageningen, an agricultural university in central Netherlands. 瓦格宁根是荷兰中部一所农业大学，里面一间特殊温室种了几十株植物。在这些植物的环绕中，韦格•沃姆林克说：“即使去了月球和火星，人也得吃饭，而自己种食物最方便。” |
