Could the promise of bringing back extinct species actually make us more careless about losing the ones we have today? That's the million-dollar question buzzing around the groundbreaking field of de-extinction.
Imagine this: just last year, a company called Colossal Biosciences made waves by announcing they had, in essence, "resurrected" the dire wolf. This wasn't just any wolf; it was a magnificent megafauna hunter that vanished from Earth a staggering 10,000 years ago. Pretty incredible, right?
But here's where it gets controversial... Within days of this announcement, a high-ranking US official, Doug Burgum, seemed to use this very idea of "resurrection" as a justification for potentially loosening environmental protection laws. His exact words? "Pick your favorite species and call up Colossal." This sentiment, unfortunately, echoed the deepest fears of many critics.
The core concern is this: if we believe we can simply bring any species back from the dead, why should we bother protecting them so fiercely in the first place? This is often referred to as the 'moral hazard' of de-extinction.
But here's where it gets interesting... A recent study published in Biological Conservation decided to put this very idea to the test. And the results might surprise you! They found no evidence that people become more accepting of extinction simply because de-extinction is on the table. Phew!
Understanding the 'Moral Hazard'
For a while now, scientists and ethicists have debated whether de-extinction technology could inadvertently undermine our efforts to conserve species that are currently alive and well. The concept of a 'moral hazard' is key here. Think of it like having comprehensive health insurance: you might be more willing to engage in risky behaviors because you know the insurance will cover the consequences. In the context of de-extinction, the 'risk' is letting a species go extinct, with the 'insurance' being the potential to bring it back later.
This debate isn't unique to de-extinction. We see similar discussions around technologies like carbon capture or solar radiation modification. The worry is that if we believe we can 'fix' climate change later, we might be less motivated to reduce emissions now. However, many studies on these other environmental policies have shown that the public's support for immediate action (like cutting emissions) doesn't necessarily decrease just because a future solution is proposed.
Our study, however, is the first to specifically investigate whether the prospect of de-extinction reduces people's concern about losing species that are currently endangered.
What the Study Revealed
The researchers presented 363 participants from diverse backgrounds with various scenarios. In these scenarios, a company's project would provide an economic or public benefit, but at the cost of an existing endangered species going extinct. For instance, one scenario involved building a highway through the last remaining habitat of the critically endangered dusky gopher frog.
Each scenario had two versions: one where the company offered 'environmental compensation' (like preserving other species), and another where they promised to use de-extinction technology to bring back a similar extinct species later.
Participants were then asked to evaluate the project's public benefit, whether the species' extinction was justified, if the compensation lessened the company's blame, and if such projects should be allowed in the future. Crucially, when de-extinction was mentioned, they were asked if they believed the company's claims about successfully recreating extinct species through genetic engineering.
A Warning Against Hype
So, what did they find? The study confirmed that the mere mention of de-extinction didn't make people more accepting of extinction compared to traditional environmental compensation. This is great news, suggesting that the 'moral hazard' argument alone isn't a strong enough reason to dismiss de-extinction entirely.
And this is the part most people miss... While the study found no evidence of a moral hazard, it did uncover a significant point of caution. There was a correlation between a person's belief that de-extinction could truly 'resurrect' a species and their belief that causing the extinction of a current species was acceptable. This is a correlation, so we can't definitively say which belief came first.
But here's where it gets controversial... It's possible that people who already believe extinction is justifiable for economic gain then adopt the view that de-extinction is possible, using it as an excuse. Or, more worryingly, the belief that de-extinction is achievable might actually lead people to view extinction as less of a tragedy. This could essentially turn the promise of de-extinction into either an excuse for extinction or even a reason for it.
This highlights a major risk: if companies and scientists involved in de-extinction overstate or mislead the public about what this technology can actually achieve, it could have serious ethical implications.
The Importance of Clear Communication
It is absolutely crucial for everyone involved in de-extinction efforts to communicate with accuracy and without hype. Claims that de-extinction can truly 'reverse' extinction are misleading. While genetic engineering can introduce lost traits from extinct species into living relatives and potentially restore some ecological functions, it cannot perfectly recreate the original extinct species.
The problem arises when companies present these limitations cautiously within the scientific community but then make much bolder, more sensational claims to the public. This fosters the false belief that extinction is fully reversible, which, in turn, undermines the very ethical basis for pursuing de-extinction in the first place.
But there's a way to avoid this pitfall! Take, for example, the project aiming to bring back the aurochs, an ancient type of cattle. They've wisely branded it as "Aurochs 2.0." This clearly communicates that they are creating an ecological proxy – something that functions similarly to the extinct species – rather than the species itself.
Companies like Colossal Biosciences have certainly attracted attention, and sometimes controversy, for publicizing projects involving the "resurrection" of iconic creatures like the woolly mammoth, the dodo, and the thylacine.
Our findings suggest that the idea that de-extinction will automatically create a moral hazard is unjustified. However, the advocates of de-extinction have a significant responsibility to be cautious and crystal clear in their communication. They must be upfront about what their groundbreaking technology can realistically achieve, and just as importantly, what it cannot.
