Firstly, the writer suggests that Torryea can be reestablished in cool and damp microclimate within Florida, while the speaker views this issue from an opposite angle. According to him, the microclimate is affected by the larger region and can hardly offer the right condition for its growth. Due to global warming and drained wetland, the environment is too dry for Torryea to survive.

　　Secondly, the author proposes that Torryea can be relocated far from where it currently grows. However, the speaker casts doubt on this proposal by raising the example of black locus tree. When it was moved far north, it spread so quickly and killed out native endangered trees. So assisted migration is ineffective for its unpredicted outcome for other species. The third measure put forward by the writer is to preserve/ develop Torryea in research centers. By contrast, in accordance with the speaker, this method is not going to work out. The reason is that research centers fail to offer enough capacity to hold large and diverse population, which is usually sufficed by natural environment where Torryea can resist diseases. As a result this method is not going to work out.
