utility 
poles
are 
collapsing
as the ground around and under them warms and softens. Also, the 
hard permafrost that originally prevented beaches from eroding during violent storms is 
now melting. People who live along Alaska’s coasts are being forced to 
relocate
. For villages 
on small low islands, one terrible storm could wipe out the entire community. 
The melting permafrost and increasing temperatures are both affecting the forests 
of Alaska. As the permafrost under the forests melts, insects that normally do not turn up 
until the warmer seasons are appearing sooner. The 
spruce
-bark beetle, for example, is 
increasing in numbers as a result of warmer winter temperatures. It usually takes about 
two years for these beetles to grow and reproduce in very cold weather. However, due to 
the increase in temperatures, spruce-bark beetles are reproducing faster and damaging 
as many trees in one year as they previously damaged in two. If something cannot be done 
to change things, Alaska’s forests will not survive the turn of the century. 
Some scientists believe that human activity is linked to a global increase in weather 
temperature. Whatever the cause of rising temperatures may be, the fact remains that 
temperatures are warming, affecting Alaska for the worse. 
Horribly
, this could be a
preview
of what will happen to the rest of the world in the next century.
