Until just a few centuries ago, the Galapagos Islands were untouched by humans and free from predators. This ecological isolation allowed for the development of some of the most unique life forms on the planet. However, many of the species of flora and fauna, while highly adapted to their harsh surroundings, are especially vulnerable when confronted by the outside world.

The ever-growing human population is simultaneously threatening and attempting to ensure the future of this archipelago. Over the last 20 years, development of the tourism industry and a boom in fishing have resulted in the growth of the local population from about 10,000 in 1990 to more than 28,000 residents in 2005. Though the current low-impact ecotourism has served the Galapagos well, historically, the influx of people has had unfortunate consequences: unknown numbers of invasive plant and animal species are driving out native species, marine resources are being harvested faster than they can be replaced, and habitats are being degraded at alarming rates.

New governmental regulations are attempting to reverse the deleterious affects of past mistakes, though, and current scientific research diligently constantly endeavors to conserve rare and dying species and protect the environments in which they live.
