Easter Island in the South Pacific is well known for the many massive carved statue heads(moai) standing all around the island. Their origins have been much debated over the years with all sorts of theories including extra-terrestrial sculptors.
Scientific research has concluded that the statues are the work of the indigenous people. How were these statues constructed and moved? The Island today is mostly barren, covered with grass and only a few trees and with a very small population (less than 5,000). In the past however the island sustained a large population, probably in the tens of thousands, and was a verdant forested island. There were sufficient resources, both human and material, to acheive the construction and placement of the moai.
The scientific conclusion is that the island was deforested by the very large poulation and as a result the population the island could support was greatly reduced. In other words the people literally consumed themselves out of house and home.
Why did would they do this? The answer is because they didn't know they were doing it. It took place over the course of many generations, with each successive generation assuming that the state of their environment was as it had always been.
Why is this important? Because this is the very same condition the whole world is now in. Each successive generation not seeing much change in the environment assumes there is no problem.
The difference of course is that we now have science. We can measure the changes in the environment. We know what we are doing to our environment. The question now is, can we change our behavior or will the Earth fall prey to the 'Easter Island Effect'?
