Ⅰ. 阅读理解
David Sischo is a wildlife biologist specialising in the conservation of rare and endangered terrestrial molluscs (软体动物). He and his colleagues have been trying to save native snails since 2012. I once visited the green trailer. The lab manager was refreshing the snails’ accommodation — an ongoing routine that takes days of careful work. When I arrived, she had found a dozen of Achatinella bulimoides. Once every individual was accounted for, she cleaned the cage and packed in new leaves. The work took much trouble, but the responsibility, she said, was like “a heavy weight sitting on you”.
The trailer is very vulnerable. It’s designed to be secure from would - be thieves, and to resist hurricanes. But a fire could easily destroy it, or a disease could sweep through it. Once a mysterious pathogen (病原体) appeared to have entered the trailer on leaves fed to the snails, killing almost the entire species. As sad as the incident was, there’s no good way to insure against future disasters. The snails can’t simply be spread among zoos or other facilities. They need dedicated (专用的) equipment, experienced handlers, and a diet of native Hawaiian plants.
Consequently, it can be hard for the snails’ minders to relax, even when they are outside the trailer. How do you switch off when your decisions mean existence or extinction? Sischo said, “If you do it wrong, the snails die.”
Snails are neither intelligent nor beloved. Sischo’s friends sometimes tease him about being “the strange snail guy”; strangers ask why he cares. Sischo tells them that the snails recycle nutrients in the forest, and feature heavily in traditional Hawaiian stories and songs. These points rarely convince people, but he insists that if he can just get them in the trailer, they will understand why the snails are worth saving. “People melt,” he said. “When you show them that the entire population is in this chamber, it hits them.”
