Their remote location meant that the islands had few visitors and almost all of the animals exhibit no natural fear of man.  However, a rising population, the presence of feral pigs and goats, and the pressures of mass tourism have begun to threaten the existence of some species.

The Galápagos Islands lie above a volcanic "hot spot" (similar to the Hawaiian Islands) where the Nazca and South American plates meet. The islands are essential the tip of giagantic shield volcano that rises up to 10000 ft above the ocean floor.  As the plate moves eastwards, new volcanic cones are formed so that the eastern islands are much older and eroded than those to the west, which are still volcanically active.
