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.
ALASKA SPECIES
Wildlife can be found everywhere in Alaska, from cities where moose, bears and wolves roam to more than 18 million acres designated by Congress
as wilderness areas as part of the National Wilderness Preservation System.
However, most refuges in Alaska require travel via air transport, making
them difficult and expensive to reach.
Many species in Alaska such as black and brown bears, wolves, moose and many others are on the verge of Extinction. They are interesting in their own way. So, let’s learn about them more than we do.
Black bears are usually smaller than brown bears. They can look alike, but there are several ways you can tell the bears apart. Black bears don't have a shoulder hump like brown bears. Black bears also have a straight face, compared to the brown bear's bowl-shaped face. Their paws are different too. Black bears' claws are short and curved and brown bears have longer, straighter claws. Black bears have been known to live in every state, except Hawaii. They can be found in most forested areas in Alaska.
Like brown bears, black bears hibernate in the winter. They start hibernating in the fall and come out of their dens in the spring. Their dens are found in hollow trees or rocks. They also build dens on the ground. A person may walk right over a bear den and not even know it, unless the bear wakes up, of course.
