In the 18th century the people of Easter Island worked hard
creating the statues that their information showed
were absolutely necessary for their future.
In the 19th century Easter Islanders realised
that statues were a useless waste of effort
and put all their energy into the obvious need
to worship the birdman.
In he 20th century the stupidity of the Easter Islanders
was obvious when everybody knew
from the examination of history
that the earth was about to enter a new ice age
and there was a need for humans
to create enough warmth for them to survive.
In the 21st century everybody worried about Kyoto and went to Copenhagen
to work out how to stop humans from making the world too hot.
With their understanding of history
world leaders failed to agree.
They bit each other vigorously,
and expressed some warm air.
In the 22nd century the world continued.
