Collapse of Ancient Civilizations
Deforestation, mining, overusing water, and massive killing of animal are common
activities existing in the modern world.
As people continue the overuse of Earth’s natural
resources, the Earth’s resources will be depleted and they will no longer be able to support life
on the planet.
Environmental problems are the biggest problem that can effect an advanced
civilization. In the past, many of the smaller advanced civilizations have collapsed due to the
natural resource depletion.
The most significant ones are the island civilization of Easter
Island the Prehistory Malta Island civilization, and the famous Maya civilization.
like the smaller scale of our world, and they reflected what will happen if we continues on
what we are doing to the natural resources right now.
First of all, the small island, Easter Island, is a Polynesian island in the southeastern
Pacific Ocean, at the southeastern most point of the Polynesian triangle.
It is about 2000
miles from the main South America land thus making it one of the world's most isolated
The island was first inhabited by people who sailed the ocean from Hawaii,
and the population was relatively small.
These first settlers were able to sustain life though
sea birds, rats, nuts, and fish.
The soil was very fertile and the food and the resources were
Life was pretty good on the island, and the population grew exponentially
As the result of the population growth, people needed more natural resources to
support their life.
They cut down more and more trees for house and fire, and they killed
more and more animals to feast on.
The palm trees once flourish on the Easter Island, now
have disappeared completely.
Shrubs and small short trees also decreased in number and
were finally replaced by abundant amount of grass patches.
Adding to the extinction of the
plants on the Easter Island, native animals which had once roamed the land also began to
Every species of native land bird became extinct.
Even shellfish were
overexploited, until people had to settle for small sea snails instead of larger cowries.
Porpoise population decreased abruptly overtime.
The colonies of more than half of the
seabird species breeding on Easter or on its offshore islets were wiped out.
In the same time of the natural resource depletion, Easter Islanders thought that god
was angry at them so he took away all the food and woods from them. As a tribute to the
good, they built the famous Moai statues. The Moai are hundreds of statues of heads that are
carved out of stone and weighs hundreds of tons. The Moai stands in the coast of the Easter
Island, but the stone used for carving these statues were from inner Easter Island. Scientist
today had no idea how they were moved so far away from the innermost island to the coast,
