So right now we are at the donor site, that's the place where we are collecting fragments of corals coming from big mother colony that are more resilient.

这里就是采集地，我们会在这里收集来自大母群落的珊瑚碎片，这些珊瑚的生命力更顽强。

Doctors can take some of the patient's healthy limbus and transplant it, but take too much and they risk causing the same problem at the donor site.

医生可以取一些患者健康的角膜缘并进行移植，但取太多可能会在供体部位引起同样的问题。
