请帮忙看og12 第一篇的一个句子

  Even a vastly more ecoefficient industrial system could, were it to grow much larger, generate more total waste and destroy more habitat and species than would a small, less ecoefficient economy.

   请问：1 were it to grow much larger 是倒装，那正确的语序是什么？

             2. 我觉得这句话语法有点不对，没有连词连接两个句子。请大家帮忙看看。

谢谢！

1. 虚拟语气。本来应该是if it were to grow much larger。

2. 没错误。主语a vastly more ecoefficent industrial system。

谓语could generate

骨架 system could, generate more waste and destroy more habitat...than a small.....economy.
