And if we really are looking at areas of land of the sort of sizes I've been talking about becoming available, why not reintroduce some of our lost megafauna, or at least species closely related to those which have become extinct everywhere?
如果我们看这些重新野化的土地 其面积可以达到我们之前所说的规模 为什么不重新引入那些我们失去的巨型动物 或者至少是与它们有密切关联的物种 那些濒临灭绝的生物？
