What caused land iguanas to become extinct on santiago?

Land iguanas became extinct on Santiago Island primarily due to the introduction of invasive species, particularly feral goats and pigs, which destroyed their habitat and competed for food. Additionally, predation by rats and dogs further threatened their survival by consuming their eggs and young. Habitat degradation and human activities also contributed to the decline of their populations. Conservation efforts have since been implemented to help restore and protect the remaining land iguanas in the Galápagos Islands.
