Species are going extinct at an alarming rate, termed by some as the sixth mass extinction event in the history of Earth. Many are the causes for this but in the end, all converge to one entity - humans. Since we are the cause, we also hold the key to making the change. Any change, however, will take time, and for some species this could be too long. While working on possible solutions, we also have the responsibility to buy time for those species on the verge of extinction. Genome resource banks, in the form of cryobanks, where samples are maintained under liquid nitrogen, are already in existence but they come with a host of drawbacks. Biomimicry - innovation inspired by Nature, has been a huge source for ideas. Searching methods that Nature utilizes to preserve biological systems for extended periods of time, we realize that drying rather than freezing is the method of choice. We thus argue here in favor of preserving at least part of the samples from critically endangered species in dry biobanks, a much safer, cost-effective, biobanking approach.
物种正以前所未有的速度灭绝，有人称之为地球历史上的第六次大灭绝事件。造成这种情况的原因有很多，但最终都归结为一个实体——人类。既然我们是造成这种情况的原因，我们也掌握着改变的关键。然而，任何改变都需要时间，而对于一些物种来说，时间可能太长了。在寻找可能的解决方案的同时，我们也有责任为那些濒临灭绝的物种争取时间。以 cryobanks 形式存在的基因组资源库，其中样本在液氮下保存，已经存在，但它们存在一系列缺点。仿生学——受自然启发的创新，一直是灵感的重要来源。我们研究了自然界用于延长生物系统保存时间的方法，意识到干燥而不是冷冻是更好的选择。因此，我们在这里主张将至少部分濒危物种的样本保存在干燥的生物库中，这是一种更安全、更具成本效益的生物库保存方法。
