[简答题]这种方法的问题在于无法大规模地实践。不幸的是，在我们的地球上高尚的野蛮人和未被破坏的风景已越来越少；除了两极地区以外，已经没有未开发的土地了。少数富有的乡绅还可以逃避现实去过田园生活——但总的来说迁移的潮流是反向流动的。

参考答案:The trouble with this solution is that it no longer is practical on a large scale. Our planet, unfortunately, is running out of noble savages and unsullied landscapes; except for the polar regions, the frontiers are gone. A few gentleman farmers with plenty of money can still escape to the bucolic life—but in general the stream of migration is flowing the other way.
