You cannot simply stroll into Darwin's evolutionary playground carrying a half-eaten bag of Doritos. The Galapagos relies on an incredibly fragile, isolated ecosystem that can be utterly devastated by a single invasive seed or foreign fruit fly hitching a ride in your trail mix. Customs agents will literally inspect your boots for mud and confiscate your precious snacks at the airport to ensure the indigenous giant tortoises don't accidentally catch a bizarre mainland plague.
