Galapagos

The episode explores the ecological transformation of the Galapagos Islands, focusing on the near-destruction of tortoise habitats by invasive goats introduced by whalers and pirates, and the subsequent eradication campaign using helicopters and sharpshooters. It highlights the tension between conservation and ethical dilemmas, while underscoring that evolutionary processes continue in real time through finch speciation. The story culminates in a symbolic political race reflecting the struggle between development and environmental protection.

It delivers a powerful, narrative-driven case study of real-world conservation science, showing how human intervention both destroys and restores ecosystems, with evolution still unfolding in one of its most iconic locations.

1. 01Goats introduced by 16th-century sailors devastated Galapagos ecosystems, leading to the destruction of tortoise habitats and drip pools.
2. 02Project Isabella used helicopter-based eradication to eliminate 100,000 goats from Isabella Island, a controversial but effective conservation strategy.
3. 03Evolution is an ongoing process in the Galapagos, with finches providing observable, real-time speciation events.
