INTRODUCTION
“Alaska’s
mountains rise like walls; four seas and unimaginable distances form a mighty
moat; and a patchwork of national parks and wildlife refuges protects more than
a third of the state. It’s a fortress for wildlife.”
Shielded
from civilization, bears, wolves, moose, and caribou cast their huge shadows
from coast to coast, and musk oxen travel the far north like refugees of the
last ice age. Migratory birds flock river deltas each summer, and raptors prowl
Alaskan skies year-round.
As
with any fortress, wild Alaska’s
perimeter is especially vulnerable. Tankers laden with oil from bays and
coastal wetlands skirt the seaboard. Though now protected, endangered whales
resist to rebuild their populations. Like sea lions
and other marine mammals, they now must compete with massive trawlers—floating
factories—for the sea’s falling harvest.
In
this research paper I would like to investigate extinction problem. Many facts
I have found show that this problem is very urgent. I am not sure that
everybody understands it but if more people realize this many problems will be
solved.
