Question

这个句子怎样理解?
"In the third phase we do not know what the limit to urbanization may be.Suffice it to say that the United States is today 73 percent urbanized,that most of the rural population is no longer engaged in farming,and that the nation nevertheless continues to be a net food exporter."
=>“在第三个阶段,我们也许无法知道都市化的界限在哪里.我们有能力这样说,现在美国的都市化率是73％,而且郊区（农村）的人也不再愿意去从事农业,即使这样我们国家还继续是食品的出口国.”
如果我的理解是可以的话,那么这个文章的作者岂不是太自大了.还是我的理解有问题.

Answer 1

第三个方面,我们也许无法知道城市化的界限在哪里.我们可以这样说,现在美国的城市化比率是73％,而且郊区（农村）的人也不再从事农业,即使这样这个国家却依然还是食品的净出口国.
urbanization翻译为城市化要好些
另外no longer engaged in farming并没有意愿杂意思在里面
