In a previous discussion, we delved into the science of de-extinction, which is the process of bringing extinct species back to life. Today, let’s dive into the philosophical and moral questions surrounding this fascinating topic.
Interest in de-extinction has grown due to the threat of a new mass extinction. Historically, mass extinctions were caused by natural events like asteroids or climate shifts. However, the current wave of extinctions is largely driven by human activities such as climate change and overpopulation. As a result, many species are disappearing rapidly. To combat this, scientists are researching ways to revive endangered species.
Some people believe we have a moral duty to restore species that have gone extinct due to human actions. Over the past 800 years, humans have contributed to the loss of many plants and animals. This raises the question: which species should we bring back? Should we focus on iconic creatures like the woolly mammoth or the thylacine, or should we prioritize species that played crucial roles in their ecosystems?
Climate change is already threatening the habitats of animals like polar bears and arctic foxes. If we bring back woolly mammoths, where would they live? Their natural habitats and food sources might no longer exist. Additionally, how would these revived species interact with current ecosystems? Could they become invasive and disrupt existing wildlife?
We are already struggling to conserve living species like Asiatic and African elephants. Should we focus our efforts on reviving extinct species that might not fit into today’s world, or should we concentrate on protecting those that are still here?
Reviving extinct species isn’t just about the science; it also involves significant costs in terms of money, time, and resources. For example, the passenger pigeon once existed in massive flocks, but they were hunted to extinction. If we brought them back, how would we manage such large populations today, especially in cities like New York that already have pigeon challenges?
What do you think about bringing extinct species back to life? Are there positive outcomes you can envision? Feel free to share your thoughts and ideas!
This discussion was inspired by a video sponsored by audible.com, offering a free audiobook to listeners. Consider checking out “On the Origin of Species” by Charles Darwin, narrated by Richard Dawkins. Thanks for joining the conversation, and stay tuned for more exciting content!
Form two groups and prepare for a debate on the ethical implications of de-extinction. One group will argue in favor of de-extinction, highlighting the potential benefits and moral responsibilities, while the other will argue against it, focusing on the challenges and ethical concerns. Present your arguments and engage in a respectful discussion.
Choose an extinct species and research its ecological role, reasons for extinction, and potential impact if revived. Present your findings to the class, explaining why this species should or should not be prioritized for de-extinction efforts.
Write a short story from the perspective of a revived extinct species. Describe its daily life, interactions with the current ecosystem, and any challenges it faces. Share your story with the class and discuss the potential real-world implications.
Conduct a cost-benefit analysis comparing the resources needed for de-extinction projects versus those required for conserving endangered species. Present your analysis and discuss which approach might be more beneficial for biodiversity and ecosystem health.
Engage in a group discussion about the long-term implications of de-extinction on biodiversity, ecosystems, and human society. Consider both positive and negative outcomes, and propose potential guidelines for responsible de-extinction practices.
Sure! Here’s a sanitized version of the YouTube transcript:

♪ On the last episode of “The Brain Scoop,” we discussed de-extinction and the science behind it. To watch that, click here. Three, two, one—too slow! Today, we’ll explore the philosophy and moral implications of de-extinction.
This renewed interest in de-extinction is partly due to an impending mass extinction. Mass extinctions have occurred before as a result of astronomical or climatic events. This current one is, in part, due to human interference. Climate change and overpopulation are leading to the rapid extinction of many species. In an effort to halt or reverse this trend, people are investing in research into de-extinction, which aims to bring back species that are currently endangered.
You could argue that this is driven by a moral obligation: if we have the ability, we should attempt to restore these species, as we played a role in their extinction. If we are responsible for the loss of various flora and fauna over the past 800 years, that raises the question of which species we should prioritize for revival. Should we focus on those that capture our imagination, like the woolly mammoth or the thylacine, or on those that have left significant ecological gaps?
Climate change is already causing habitat loss for creatures like the polar bear and arctic fox. How can we sustain a population of woolly mammoths in the same environment? Their diet and ecological niches may no longer exist, and they may have nowhere to thrive. If brought back, how would they affect existing species? Would they be considered invasive or endemic?
We are already facing challenges in conserving current populations of Asiatic and African elephants. Should our conservation efforts focus on reviving a woolly mammoth, which might not fit into the current ecological framework, or should we prioritize the conservation of species that are still present?
If we choose to bring these species back, where do we draw the line regarding costs—not just financial, but also in terms of time, energy, resources, and national funding? The passenger pigeon was once a highly prolific species, with flocks of millions blocking sunlight over cities until they were hunted to extinction. What would happen with such large populations today? New York already faces challenges with its pigeon population. Why introduce an extinct species?
It might be clear how I feel, but I’d love to hear your thoughts. What positive implications do you see in bringing them back? Leave a comment below.

De-extinction – The process of reviving extinct species through scientific methods such as cloning or genetic engineering. – Scientists are exploring de-extinction to bring back species like the woolly mammoth, which could help restore ecosystems.
Species – A group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding. – The giant panda is a species that has been the focus of many conservation efforts due to its declining population.
Extinction – The state or process of a species, family, or larger group being or becoming extinct. – The extinction of the dodo bird serves as a reminder of the impact humans can have on wildlife.
Ecosystems – A biological community of interacting organisms and their physical environment. – Coral reefs are vital ecosystems that support a diverse range of marine life.
Climate – The long-term pattern of weather conditions in a region, including temperature, humidity, and precipitation. – Changes in climate can significantly affect the distribution of species across the planet.
Responsibility – The state or fact of having a duty to deal with something or of having control over someone. – It is our responsibility to protect endangered species and preserve biodiversity for future generations.
Conservation – The protection and preservation of natural resources and environments. – Conservation efforts are crucial to maintaining the balance of ecosystems and preventing species extinction.
Habitats – The natural home or environment of an animal, plant, or other organism. – Deforestation is a major threat to the habitats of many wildlife species.
Resources – A stock or supply of materials, staff, and other assets that can be drawn on by a person or organization in order to function effectively. – Sustainable management of natural resources is essential for the health of our planet.
Ethics – Moral principles that govern a person’s behavior or the conducting of an activity. – The ethics of genetic engineering in de-extinction raise important questions about the consequences of bringing back extinct species.
