Bears can be found all over the world. There are many things we don’t know about bears because we usually don’t have very much contact with them. For example, Bears can run almost 65 kilometers per hour, fast (1 ) ……… to catch a running horse. The fastest known human alive today can run about 43 kilometers per hour.
Bears live in forests, mountains, deserts and grassy areas. They have fur-covered bodies, short legs and a round head with a long snout. In fact bears have two layers of fur. A short layer of fur keeps the bear warm and a long layer keeps water (2 ) ……… from the skin and short fur.
Of course, there are different (3 ) ……… of bears but one of the most common bears is the brown bear.
Bears are omnivorous, (4) ……… they eat vegetation and meat. The brown bear's diet is quite similar to all other bears. They eat grass, fruit, insects, roots and bulbs of plants and, when hungry enough, will hunt small animals. Brown bears that live near the coast feed on fish, (5 ) ……… salmon.

Grizzly bears live in a variety of environments .All of which includes dense forests, subalpine meadows, open plains and arctic tundra . In the past though, they could be found from Alaska to Mexico, and from California to Ohio. Though Nowadays there are efforts trying to make it so grizzly bears can make a comeback and the wild, and all of their efforts are proving to be working, there are 4 times as many grizzlies in the wild as there were in 1975, at
To begin with, the melting of polar ice caps has caused polar bears to swim long distances. According to Bryan Walsh of TIME Magazine the melting of the ice caps have caused polar bears especially the young cubs to swim longer distances which has caused a “ forty-five percent mortality rate” (Walsh). In the article Walsh, writes about a study that showed that younger cubs because of low fat and strength were more likely to die due to the long di...
Although they are now rare, grizzly bears inhabit the dense forest of Montana’s Rocky Mountains. Grizzlies grow as tall as eight feet and can weigh up than 1,000 pounds, yet they can move as fast as a horse. There are six national grizzly recovery zones, and three are in Montana. They are Cabinet-Yaak, Northern Continental Divided, and Yellowstone (Av2 books).
Bears can live anywhere but Grizzly bears live in subalpine meadows and dense forests. When grizzly bears hibernate they usually live in caves. A sloth of bears is usually a mom and the cubs. The mom bear is called a sow, the dad bear doesn't have a name because they are never with the family and the babies are called cubs. There is usually a dearth amount of cubs in a family. The families are always together and not with a different family. All bear look different but I'm not talking about the other bears I am talking about grizzly bears. Grizzly bears are usually just the color brown and not really anything different. Grizzlys need big paws to get around and travel. Bears have small black eyes. Their eyes are small because they don't need very good eyesight because they have such good sniffers. Usually the weight of a cub is about 4- 10 pounds when they are born but when they are adults they weigh 175- 500 pounds.
The grizzly bear trophy hunt is an issue regarding the citizens of Canada who immorally hunt and kill grizzly bears for pride, thrill, and trophy. Many people question whether this is morally acceptable as hunters kill without a conscience. Grizzly bears are vital to Canada’s environment as they are essential to maintaining a healthy ecosystem. As keystone species, they regulate prey, disperse seeds of plants,and aerate soil to maintaining forest health. Due to the vulnerability and over-hunting of grizzly bears, Pacific Wild and many other non-profit organizations, are working to protect wildlife in British Columbia, especially the grizzly bear habitat.
Grizzly bears are enormous bears; that, tend to be misunderstood by others. Many times, they are portrayed wrongly in movies and tv shows. People may go off by things they see; in the movies and immediately suggest that’s the way the grizzly bear is. If others took the time to find information on the grizzly they would see how wrong the movies are about them. For many people grizzly bears can be a mystery such as where they live, what they eat, and whether they hibernate or not. However, with a bit of research answers can be found.
grizzly bears prefered habitat is deserted rivers, wild mountains, and thick and dense forest. Grizzly bears are majestic symbols of the wild. Bears live in and use a variety of habitat types, playing important roles in each one. This makes them an “umbrella species,” meaning that when we protect them and their habitat we also protect many species. Grizzly bears can also help ecosystems by distributing seeds and nutrients through their scat, and occasionally regulating ungulate populations.
Out of an Ice Age emerged one of our most majestic creatures in the world the polar bear. From its brown bear ancestry, the predator evolved to be a master of a harsh and unwelcoming ice kingdom. Intelligent, adaptable and fierce, the polar bear learned how to survive in a place that offers few comforts to any creature. But now that very environment is in flux. And so is the polar bear’s fate (Nature). Polar Bears are very different from other bears. Polar bears are very large bears compared to Black bears. Polar bears weigh anywhere between 330-1700lbs and Black bears weigh anywhere between 150-600lbs. They have strong legs with large, flattened feet with some webbing between their toes that help with walking on ice and swimming. The wide paws prevent sea ice from breaking by distributing weight while walking. Their paws allow them to pull a 600 pound seal out of its breathing hole (Rosing, 20). The webbed feet results in making polar bears, unlike other bear species to be considered as marine mammals along with seals, sea lions, walruses, whales and dolphins (Polar Bear). According to Rosing Polar bears are excellent swimmers and have been known to swim up to six miles an hour and as far as 60 miles at a stretch. The bears paddle with their front feet and steer with their back feet. They often overheat. Sometimes they venture into the waters just to cool off. When a bear climbs on an ice floe, it shakes itself off because it is trying to prevent ice from forming on its fur (22-23). Because of climate change and hunting of polar bears are now becoming an endangered species which is affecting the food chain. We can fix this by going green, banning polar bear hunting and keep creating these new hybrid bears that are mixed with griz...
* Perhaps the most noticeable and striking characteristics of a polar bear is its color. The fur shafts themselves are not white. The shafts actually lack pigmentation and are transparent which allows them to scatter and reflect light resulting in ideal camouflage in a world of ice and snow.
Black bears in Alaska range from sea level to the wooded forest. Where they live depends on what time of the year it is. Most black bears are not found on islands in the Gulf of Alaska, but some are found in the southeast near those islands except for Admiralty, Baranof, Chichagof, and Kruzof. They are not on these islands because most are inhabited by brown bears and most bears like to keep to themselves. You hear more about bears that live in the forest then the ones that live by the sea. The habitat of a black bear that lives in the forest is normally wooded areas that has thick vegetation.
According to the Alaska Department of Fish and Game, the brown bear is located all throughout Alaska, mostly in areas that allow them to seasonally hunt salmon (Alaska Fish & Game, 2010). This allows them to become larger and live in higher concentrations than the grizzly bear. The traditional brown bear and the grizzly bear are actually both classified as brown bears, despite having several differences in appearance. Brown bears are one of the most fascinating and powerful species in the Alaskan wilderness. Cubs are usually born during January or February, usually in groups of one to four (Alaska Fish & Game). A fully grown, male brown bear can weigh up for 1,500 pounds and be over 10 feet in stature (Alaska Fish & Game, 2010). Brown bears also have the ability to run at speeds up to 40 mph for short bursts of time (Alaska Fish & Game). All of these unique characteristics make many people upset that it is legal to hunt them. There are several groups that are working to conserve the brown bear population, particularly in Alaska, such as The Northern Forum’s Brown Bear Working Group (Fish & Wildlife Journal, 2010). The bear population in Alaska is thriving and is classified as a status of least concern, by the IUCN Red List (IUCN, 2010). Overall, the brown bear population faces no danger whatsoever.
One way that the environment impacts the animals is that the animals such as bears adapt and store their energy in the winter. This is also known as hibernating. “Animals in the mountains have also adapted to save energy during the harsh winter months.” (Cassandra Maier, Adaptations of plants and animals to mountains) When animals hibernate, they are less active during the winter, and they just sleep for most of the day. Other animals such as the goat and deer do not hibernate during the winter,
Polar bears prefer to live in extremely cold artic climates. They live only in the Northern Hemisphere, on the arctic ice cap, and they spend most of their time on coastal areas. Polar bears are widely spread in Canada, extending from the northern arctic islands south to the Hudson Bay area. They are also found in Greenland, on islands off the shore of Norway, on the northern coast of the former Soviet Union, and on the northern and northwestern coasts of Alaska in the United States.
