On October 1, 2024, Romulus and Remus, the world’s first de-extinct animals, were born: dire wolves, extinct for over 10,000 years.

Created through CRISPR technology by Colossal Biosciences, their birth marks a new era in genetic science. But while this is an incredible scientific feat, it raises serious questions about the future of our ecosystems and the animals that share it.

Colossal plans to bring back other extinct species like the woolly mammoth and thylacine, potentially boosting biodiversity and combating climate change. 

However, we cannot afford to rush headlong into de-extinction without a clear and thoughtful plan. Bringing extinct animals back to life sounds incredible, but the implications are far more complex than they appear.

• Where will these animals live? Modern ecosystems have moved on. Reintroducing ancient species could disrupt delicate ecological balances.
• What about the animals themselves? Being “reborn” doesn’t guarantee survival in today’s world.
• What about the species we still have? While reviving extinct animals, we risk neglecting endangered species that need urgent protection.
• Are we forgetting the ethics? De-extinction might make people believe extinct species can always be brought back, instead of focusing on preserving those still alive.

We need to proceed with caution. De-extinction must be carefully planned with ecological responsibility, transparency, and a deep understanding of its potential impact.

We call for a moratorium on future de-extinction projects until a responsible, scientifically sound plan is developed.

Join us in demanding a pause on dangerous de-extinction efforts until we have a clear, ethical path forward.
