标题: 急问这个they指代谁？

  Industrialization and modern methods of insect control have improved the standard of living around the globe while at the same time they
            have introduced some 100,000 dangerous chemical pollutants,having gone virtually unregulated since they were developed more than 50 years ago. 

请问这两个they 分别指代谁？指代一样吗？都有指代吗？  谢谢

急问！

第一人They指 (Industrialization and modern) methods

第二个They指 (dangerous chemical) pollutants

That's what I think.
