Which of these is a likely application of a gene drive?

The application of a gene drive to eliminate an invasive species is grounded in the mechanism by which gene drives operate. Gene drives utilize genetic editing technologies, such as CRISPR, to spread a particular genetic alteration through a population at an accelerated rate. This strategy can be particularly useful for controlling or eradicating invasive species that threaten native ecosystems. By modifying the genetics of an invasive species so that it can no longer reproduce effectively or survives poorly in its environment, the gene drive can help restore ecological balance and protect biodiversity.

Utilizing gene drives for invasive species management also highlights a proactive approach in conservation efforts. Unlike traditional methods, which may rely on chemical control or physical removal, gene drives have the potential to achieve lasting change by altering reproductive rates or behaviors in a way that integrates seamlessly into the species' natural lifecycle.

While the other applications listed might also contribute to biodiversity or human welfare, they do not specifically align with the unique characteristics and intention of gene drive technology. For example, enhancing crop resilience primarily focuses on agricultural outputs, while improving human health and creating GMOs for food rely more on established genetic modification rather than the rapid population-level impacts that a gene drive could facilitate in invasive species.
