Easter Island -

. .

Résumé :
Easter Island, a World Heritage Site is still, after over 50 years since Thor Heyerdahl's work on the island, a fascinating area to explore and learn about a culture that has only remnants remaining, while documenting a marine ecology still mostly unknown. Easter Island: Scientific Exploration into the World's Environmental Problems in Microcosm presents the research results from three years of interdisciplinary expeditions to Easter Island. The primary objectives were to investigate the effects of human population growth on the ecology of the island and to discover whether any dramatic climatic changes such as a prolonged El Ni?o could have disrupted the island's fragile ecosystem. The interdisciplinary scientific team were mainly researching the paleontology, archaeology, climatology, and geophysics of the island. This book now brings together the results of the three expeditions, identifies new areas of research, and hopefully will continue to inspire aspiring scientists to revisit this amazing island to explore and demystify this timeless enigma of human history.
