CRISPR as a way to eradicate invasive species? Tell me more…

The way to kill invasive species, and thereby protect endangered species are brutal—traps, long-range rifles, and poisons—deployable only on a small scale and wildly indiscriminate. To excise the rat, say, from an ecosystem requires a sledgehammer that falls on many species.

All this is why some conservation biologists such as Karl Campbell has begun pushing for research into a much more precise and effective tool—one you might not associate with nature-loving conservationists. Self-­perpetuating synthetic genetic machines called gene drives could someday alter not just one gene or one rat or even a population of rats but an entire species—of rats, mosquitoes, ticks, or any creature. And this biological technology promises to eliminate these destructive animals without shedding a drop of blood.

But the methods also contain the threat of unleashing another problem: They could change species, populations, and ecosystems in unintended and unstoppable ways.
