...The Survival And Cubbing of Polar Bears The survival and cubbing of Polar bears is rapidly getting affected due to climate change and Global Warming, as says the Wildlife technical report(Michelle Allsopp, 2012). The healthy breeding of Polar bears relies greatly on the Arctic’s ice covered waters and cultivate Arctic Wildlife, as well. Polar bears are the most precious habitats of Arctic wildlife, Not only because they are limited in numbers but also on the grounds that the specie have now endangered for conservation. According to authentic information(Michelle Allsopp, 2012), a female Polar bears can only give birth to 1 to 3 cubs with in life time. Also, the mortality rate of infant cubs exceed from 70 %. Hence, there are less chances that the individuals of the Polar bears can be replaced by new generations. Furthermore, the other factors of climate change and global warming have intensified the threat to the species conservation due to climate changes in Arctic Wildlife. The projected claim can be justified with supporting observations presented below for reference. * Comprised survival rates of sub adult due to poor nutritions resulted from the sea ice breakup. * Inefficient reproduction cycle due to early spring ice breakup. * Deprived access to prey for sufficient...

...endangered species project is a polar bear. These beautiful mammals have a pigment-free, transparent coat that is about 2.5 to 5 cm think. It is composed of a dense, protective undercoat that is covered with different lengths of guard hairs. The polar bear’s fur appears to be white, yellow, and sometimes brown, because each of the hair shafts, which cover its coat are un-pigment, transparent, and have a hollow core that reflects and scatters visible light. Also, underneath all of the fur they have black skin, however it only visible on it’s nose and footpads. The black skin enables the bear to absorb sunlight, so that it can stay warm. Unlike many of its relatives, polar bears have lengthier heads and necks, and their body shaped is more slender. These bears are the largest carnivores that live on land. An adult male can weigh about 775 to 1,200 pounds, and a full-grown female can typically weigh around 330 to 650 pounds. Polar bears have many characteristics that help them to survive in such a cold environment. Their paws are thickly coated with fur, for warmth, and the pads on the bottom of their feet are rough, and provide them with more traction, when they are...

...about the cute, white polar bears living up in the north. However, one thing you may or may not know is that because of the high demand of polar bear fur, their meat being one of the main sources of food for the native people of the north, and tourist not being careful when visiting polar bear habitats, the polar bear population in Canada has started to decline at a rate which may cause them to become endangered and then extinct in the near future. Now with polar bears being the main predators in the North Pole and the largest land predators in the world, a threat to the polar bear population is a very big deal and would have a big impact on the terrestrial and aquatic ecosystems up in the northern regions. Polar bears...

...Save the Polar Bears! Reduce Your Carbon Footprint Polar bears are some of the world’s most majestic animals, but their survival is being threatened due to climate change. Their habitat is diminishing. Polar bears need ice to move around so they can easily find food to sustain life. Some areas of the Arctic provide sea ice year-round and in other areas it melts off every year. Governments and scientists have designated 19 populations of polar bears based in four different sea ice regions in the North Circumpolar Region known as the Arctic. These four regions vary greatly when it comes to sea ice, geography and climate change (Polar Bears International, September 2017). The first area is known as seasonal ice. This is the southern...

...Polar Bears I did my favorite organism on Polar Bears. I chose this animal because it is very interesting on how they live and how they survive. The temperatures in the Arctic tundra vary from 50 degrees fahrenheit to -37 degrees fahrenheit. The diet of a Polar bear is a variety of different organism that live in the arctic tundra. But one thing the Polar bear likes the most is seals and bearded seals. I think that they eat this as their main source of food because they spend a lot of time in the water and the Polar bear is considered a marine animal. They are also known to eat walrus,beluga, and whale. I find it very interesting that they eat a whale considering how big whales can be. But when they cannot find any of the organism to eat they will go and eat some of the very few species of plants that grow in the arctic Tundra. The population of a polar bear is around 20,000-25,000 polar bears in the world. But one issue that is affecting the population is global warming and that is making the ice break up and warming the ocean and if there is no ice that means that there is no Polar bear....

...Polar Bears: WWF Polar bears are classified as marine animals because they spend most of their life on the ice from the Arctic Ocean. Their bodies are structured with layers of fat along with water resistant fur to stay warm in such cold, wet conditions. They spend about 50% of their time hunting for seals, which most of their diet consists of. Recently, the polar bear population has significantly declined due to climate change. Because of oil spills, the warming of the atmosphere and illegal hunting of the species, polar bears are now listed as an endangered species. The Worldwide Wildlife Fund is making efforts to increase polar bear population by decreasing human pollution, preventing conflict between humans and polar bears, and...

...Polar bears are known for their vibrant white coat of fur. They have adapted this beneficial trait to help them survive and it provides the polar bear with fitness in its environments.this trait makes the polar bear white and makes them blend in with those icy surroundings. The hairs on a polar bear aren't actually white but appear white and thats what helps them blend in here's how the fur looks white,the polar bears long outer hairs that protect their undercoat are transparent and the thinner hairs are colorless as well. This makes it appear white because of the air spaces.when it reflects the colors and the light it appears white on the polar bear. The trait helps the polar bear stay safe from predators, and makes it so they can sneak up...

...Kohen Stuart Mrs. Dene’/Mr. Miller English-Science/7A 24 April 2018 Polar Bears Did you know that Polar Bears are the largest member of the bear family? Males are 8-11 feet tall and 500-1400 pounds. Females are 6-8 feet tall and weigh up to 750 pounds. They are a species that thrive in the changing environment around them. They have many ways of hunting their favorite prey, the Ringed Seal. Their habitat and diet are very unique to them. There are many threats to the species. They are trying their best to save this wonderful species. Some of the threat to this species are habitat loss to Global Warming. The only humans available to harvest this beautiful animal are the Eskimo that have been hunting them for hundreds of years to survive. Many people go on guided hunts just to kill this majestic beast only want the males. This leaves many females without mates, which is not good for the population. This means that there are not many reproducing pairs left to give birth to cubs. The average litter size for the Polar Bear is about 2-3 cubs. They have a below average survival rate of 43% survival, which is only about one from every pair are making it to adulthood. The Breeding ages of Polar Bears are about 3 to 5 years old, and the numbers are slowly declining.There are currently about 3,500 in...

...of Polar Bears (Ursus maritimus) in the Canadian Arctic IAN STIRLING1 and CLAIRE L. PARKINSON2 (Received 10 November 2005; accepted in revised form 25 January 2006) ABSTRACT. Polar bears depend on sea ice for survival. Climate warming in the Arctic has caused significant declines in total cover and thickness of sea ice in the polar basin and progressively earlier breakup in some areas. Inuit hunters in the areas of four polar bear populations in the eastern Canadian Arctic (including Western Hudson Bay) have reported seeing more bears near settlements during the open-water period in recent years. In a fifth ecologically similar population, no changes have yet been reported by Inuit hunters. These observations, interpreted as evidence of increasing population size, have resulted in increases in hunting quotas. However, long-term data on the population size and body condition of polar bears in Western Hudson Bay, as well as population and harvest data from Baffin Bay, make it clear that those two populations at least are more likely to be declining, not increasing. While the ecological details vary in the regions occupied by the five different populations discussed in this paper, analysis of passive-microwave satellite imagery beginning in the late 1970s indicates that the sea ice is breaking up at progressively earlier dates, so that bears must fast for longer periods during the open-water season. Thus, at least part of the explanation for the appearance of more bears near...

...Clueless About The Climate” the authors Matt Patterson and Jerrald Hayes are having very different opinions and points of view on the subject global warming and climate-change. Matt Patterson, the author of “Warming, not!”, is a conservative political writer and the article is published in New York Post. Patterson claims that the evidence for global warming has been exaggerated and is just plain wrong. He states that the climate-change theory is facing a sudden collapse, because of two recent arguments: The first argument being the observations that Monnett and fellow researcher Jeffrey Gleason made in 2004 - of four polar bears drowning after being forced to swim long distances in the open sea, because of the climate changes - are now being questioned and investigated. Monnett has now been put on “leave” due to integrity issues. The other argument being a paper published in the peer-reviewed journal ‘Remote Sensing’ by Drs. Roy Spencer and Danny Braswell. The two scientists had compared the predictions about what the atmosphere ‘should’ do and what satellite data actually showed during the 18 months before and after warming event. They found that the computer models vastly overestimated the greenhouse effect. According to the two scientists the Earth is far more capable of equalizing its own temperature than people might think. Matt Patterson closes the article saying that there is a huge discrepancy between global-warming theory and actual, observable reality. Therefore,...

...Atmospheric Pollution As I had started my research on atmospheric pollution, I had come to find that it all coincides with global warming. Due to the gases that are being released in the air from vehicles, it starts to destroy the atmosphere. However, it is not just the gases from the vehicles, there are also gases from power plants and aerosol cans, for example, hairspray. Smokers also contribute to the pollution in the atmosphere. All of this will be discussed further into the paper. The one thing that was asked was to give a detailed description of the problem. Coming up with a detailed description was not a problem but difficult and time consuming. I have come up with a number of problems that atmospheric pollution, or global warming, has on people, animals and the world. Map Results I have found a map that shows the locations where there is air pollution. On this map, there are images of blue, purple and red dots. These dots represent the U.S. Industrial facilities that use toxic chemicals. The city and states with a high count of toxic usage had the blue and red dots next to them. These city and states are as follows: Phoenix, Arizona, Salt Lake City, Utah, San Diego, California, Los Angeles, California, Riverside, California, Bakersfield, California, San Francisco, California, Stockton, California, Sacramento, California, Las Vegas, Nevada, Portland, Oregon, and Seattle Washington. There are 34 city and states including Canada that are highlighted...

...CHANGES FOR THE BETTER Marilyn J. Holmes ENGL 101-B07 LUO (APA) Mr. Brian Powell Liberty University Changes For The Better “Through him all things were made; without him nothing was made that has been made” (John 1:3 New International Version). The environment is something that we as humans often take for granted. Making up everything that surrounds us, you would think that more of our population would take this blessing into more consideration. The actions we take for our environment do not compare to those taken against it. With it being a Christian’s responsibility to preserve and protect this God given Earth, we shall always try our hardest to fulfill his expectations. Sure we can put our recycling bins out on the curb once a week or maybe even pick up trash we see in our parks (which the average person refuses to do), but I feel that we need to take more responsibility and create a more healthy environment. We need to take charge and start promoting a more all-around environment conscious lifestyle to keep this blessing that God gave to us alive. Statistics have shown that the effects humans have on Earth are ever-growing and if we don’t change our ways now, who knows what the future may be like. The toll for not being “green” will definitely have a detrimental effect on us and our next generations. Environmental issues are growing before our eyes. Coral reefs are losing life which causes fish to have to survive without shelter, bees are disappearing leaving a huge...

...Biodiversity Paper Bio/280 What is it that we think of when the words conservation biology is spoken? The meaning of this relates to the study of nature through scientific research and data. This is a part of science that relates to the status of earths biodiversities and the protection of ecosystems, species, and habitats. With protection being a key word that relates to keeping species from extinction. A human interaction that is put in place to help solve issues that arise in a scientific value of species and nature. Biodiversity is the number of species in a certain region, habitat, ecosystem, that includes plant life also. The overall data of organisms that are still within our regional ecosystems. A species it a group organism that thrives and lives in an ecosystem. Threaten species is a group of organisms that is a step below endangered, a species that is close to endangered. Such as the polar bears, as the global warming issue has implemented reasons to believe as part of the cause of this species for being on the threatened list (Jaymi Heimbuch, 2011). Judges have passed a provision to keep these animals on this list to see if humans can reduce and turn around the global warming affect in the ecosystem that polar bears reside. Endangered species are ones that are on the brink of extinction. The marine sea turtles have been on endangered species list due to the years it takes many of the new born turtles to mature. Many die off in the first year of life...

...An Interconnection of Consequences Caused by Global Warming. (A Reaction Paper on a film “An Inconvenient Truth” by “Al Gore”) Earth is a very beautiful place every human being lives in. It is so beautiful that every details of it works perfectly fine in order for us to live in a very harmonious, lovely and peaceful way. But what if it is being destroyed by “US” who lives in it and make it suffer as much as it could to work perfectly for us in order to live in? Will it ever survive? Will it keep giving us all the things that we need? Will we ever make a move to rescue it and bring it back to where it should always be? These are some questions that rise up in my mind about global warming and its effect in human kind. Greenhouse effect The "greenhouse effect" is the warming that happens when certain gases in Earth's atmosphere trap heat. These gases let in light but keep heat from escaping, like the glass walls of a greenhouse. First, sunlight shines onto the Earth's surface, where it is absorbed and then radiates back into the atmosphere as heat. In the atmosphere, “greenhouse” gases trap some of this heat, and the rest escapes into space. The more greenhouse gases are in the atmosphere, the more heat gets trapped. This greenhouse effect is what keeps the Earth's climate livable. Without it, the Earth's surface would be an average of about 60 degrees Fahrenheit cooler. Causes of Global Warming Glaciers are melting, sea levels...
