The discovery of CRISPR/Cas9 has opened new avenues in gene editing. This system, usually considered as molecular scissors, permits the cutting of the DNA at a targeted site allowing the introduction of new genes or the removal or the modification of existing ones. The genome-editing, involving gene drive or not, is then considered with a strong interest in a variety of fields ranging from agriculture to public health and conservation biology. Given its controversial aspects, it is then no surprise that actors in biodiversity conservation do express conflicting views on this emerging and disruptive technology. The positions are ranging from a request for a moratorium to the will to test and deploy it in strategies aiming at eradicating invasive species of mammals on islands. Reviewing some of its recent developments brings light on the conflicts of interest, the financial support, and lobbying currently occurring in this growing field of biotechnology. While an optimistic view on the use of gene drive for ecosystem conservation was first promoted by several molecular biologists, the risks and uncertainties associated have now led to some reservations. Overall, the eventual use of this novel approach for conservation raises concerns related to the engagement of the public, the communication between scientists, and the public and the risk of a manufactured consent. There are also a series of essential ethical and philosophical questions on the relations we have with Nature that needs to be answered.
CRISPR/Cas9的发现为基因编辑开辟了新途径。这个系统通常被视为分子剪刀,能够在目标位点切割DNA,从而实现新基因的导入,或对现有基因的去除或修饰。基因组编辑,无论是否涉及基因驱动,都在从农业到公共卫生和保护生物学等各个领域引发了浓厚兴趣。鉴于其存在争议的方面,生物多样性保护领域的相关人士对这项新兴的颠覆性技术表达出相互冲突的观点也就不足为奇了。这些立场各不相同,从要求暂停使用到希望在旨在根除岛屿上入侵哺乳动物物种的策略中进行测试和应用。回顾其最近的一些发展情况,可以揭示出在这个不断发展的生物技术领域中目前存在的利益冲突、资金支持和游说活动。虽然一些分子生物学家最初对利用基因驱动进行生态系统保护持乐观态度,但与之相关的风险和不确定性现在已经引发了一些保留意见。总体而言,这种新颖的保护方法的最终应用引发了与公众参与、科学家与公众之间的沟通以及人为达成共识的风险相关的担忧。在我们与自然的关系方面,也存在一系列亟待解答的重要伦理和哲学问题。
