Global warming
Do you ever wonder why Sea levels are rising? This is all because of global warming. Global warming makes ice in Antarctica melt. If you’re wondering why this happens well it’s because because of all the fossil fuels we burn. When we burn fossil fuels it releases warm gases into our atmosphere. Which could make it hotter for us. First, factories around the world release different types of gases that it’s said to be like a thermal jacket on the earth. One of them is said to be carbon dioxide. Carbon dioxide is a hot gas that gets trapped in our atmosphere when fossil fuels are burned.According to nationalgeographic.com, Greenhouse gases effect is a warming that happens when gases in the earth's atmosphere traps heat. Another gas that does a lot of damage is sulfur dioxide. this gas can cause breathing problems for all living creatures when burned.And every day we burn more and more which can someday cause big droughts.

Some animals can you keep up with this but Animals such as penguins, polar bears, and even ringed seals are in danger. Polar bears are known to be strong swimmers but can they swim forever?. According to Thoughtco.com negative effects of global warming change the population of polar bears. is Global warming is really affecting Antarctica because it is melting all the ice. This causes the Sea levels to rise and this also means that animals there have less ice to be on. ringed seals need ice to make nest for their babies. but what will happen without all that ice? Where will the ringed seals, make their nest. With smaller bodies of ice to be on, it makes it harder for polar bears to hunt for their prey. Global warming Really makes it difficult for these
There are about 100 different species of animals there, all of which are affected by climate change, but polar bears the worst. Polar bears are the most sensitive to the rapid change in climate because most of their life is spent on sea ice. With the temperatures rising in the Beringia Upland Tundra, the sea ice they thrive on is melting at a very high rate (Powell). Without this ice, the polar bears will not be able to easily move around to mate with other polar bears. They will also not be able to successful hunts on seals because the seals will see them swimming and swim away before anything bad can happen to them. If there was not a shortage of ice, the seals would not see the polar bears on the ice and they would swim closer to the surface. Another challenge the polar bears will face is that they will be eventually forced to go on to the seashore. This would be catastrophic because there would be and increase of competition for food. This could start massive stampedes that could kill polar bear cubs due to adult polar bears trampling them. As of now, there are only 26,000 wild polar bears alive. By 2050, it is predicted that two thirds of all wild polar bears will be gone. By 2100, it is predicted that polar bears will become extinct if nothing is done about global warming and climate change (Kliskey). Another animal in the Beringia Upland Tundra that is affected by climate change in
Climate change is one of the causes that have been effecting the polar bears survival. Climate change is caused by the greenhouse gases, which are human’s emissions in their every day life use. These emissions form an outer warm layer in the atmosphere that will keep the earth warmer than the normal all around the world. As the atmosphere gets surrounded by these emissions that makes it warmer the sea ice in the area where polar bears live starts to melt causing the endangerment of the polar bears. Polar bears rely on Sea ice for hunting seals one of their main prey becoming complicated to retrieve causing bears to suffer starvation for the lack of time to hunt the prey.
In Shakespeare’s play, Macbeth, ambition is an important influence to much of the plot, especially the title character’s ambition. The role of ambition is predominantly brought upon the three witches who reveal two facts and a prophecy about Macbeth upon their consultation with him and Banquo. Macbeth lacks any noteable intentions, however his desire to become king heightens when the witches foretell that he will be king. The witches’ predictions influence Macbeth’s aspirations because he had no intent to be king until they predicted he would be. Macbeth’s belief in the prophecies affected his ambitions.
The quantities of polar bears will decrease because the rate of reproductive of female polar bears has declined. Pregnant female polar bears select to walk or swim to the coast and dig a den because they need to born with their offspring in the den. The ANDREW E. DEROCHER indicate that “however, this requires either that the ice drifts or freezes early enough in the fall for pregnant females to be able to either walk or swim to the coast”(166). Exactly, if the ice is enough, the pregnant females polar bears can successful walk or swim to the coast. However, the global warming is deeply affect the Arctic ice because most of ice is melting.
Polar Bears rely upon sea ice for survival. They hunt on seals that are found on sea ice. Climate change and the atmospheric warming have caused the Arctic ice to melt, resulting in loss of habitats for polar bears. This essay will focus on how has climate change and increase in temperature affected the polar bears and what can we do about it.
The main cause of global warming is “greenhouse effect.” Greenhouse effect is gases that are released into the atmosphere that do not escape into space, the gases that contribute are: water vapor, nitrous oxide, carbon dioxide, and methane. “The most important greenhouse gas is carbon dioxide, emitted by the burning of fossil fuels, and the clearing of forests” (Climate Change). The stronger greenhouse effects are it will warm up the Earth, and ocean’s causing glaciers, and other ice to melt increasing sea level (“A Blanket”). When ice melts, and glaciers start to disappear it is hard for polar bears to live because the remaining ice that is left gets farther from shore. It makes it harder for polar bears to hunt, and can be brutal to them as they try to swim back because of such big waves the glaciers cause. ). “In 2004, biologists discovered four drowned polar bears in the Beaufort Sea, and suspect the actual number of drowned bears may have been considerably greater” (“Global Warming”). When those four polar bears were out in the sea, they were probably looking for food, and since the ice is melting is it makes it extremely harder for them to hunt. Polar bears eat walruses, narwhals, beluga, whales, and many types of seals. Polar bears “still-hunt” which is to sit silently, and watch for prey to go to a breathing hole, when they come up for air that’s then the polar bear strikes (Sionger). Polar bears do everything on the ice, they rely on it to hunt, sleep, and live
Summary Polar bears are an important arctic species that are in danger of extinction because of climate change. Polar bears are known as a keystone species, meaning they have significant effect on the environment in which they live. As such, keeping polar bears alive is essential for a balanced ecosystem in the Arctic Circle. One of the major threats to polar bears is melting sea ice. As the overall temperature of the earth increases due to global warming and the greenhouse effect, the sea ice that polar bears live on for most of their lives is melting.
combustion of fossil fuel which releases CO2 . Over the last hundred years, Global warming has
Polar bears are one of the first animals that would go extinct if Global Warming continues or starts, depending on your opinion. They are not extinct quite yet, but are surely endangered. Hunters contribute to this issue often and it is illegal in many areas, but in some it is still legal. Some researchers have estimated to there being from 22,000 to 40,000 polar bears left which is why they need to be better protected and saved.
There are so many consequences because of global warming and humans polluting. As a result of global warming, the polar bear habitat is getting demolished. The warmer temperatures are melting the ice in the Arctic and North Pole. Polar bears are travelling miles and miles to find ice. Polar bears live, eat, and raise their cubs on Arctic ice, which is breaking up and melting at an alarming rate. Year by year, this problem will get worse and worse. Humans and factories throw away their waste in the ocean and it goes in the water the fish and animals drink. Polar bears eat fish and they are affected by this polluted water as well. Hunters kill many animals including the polar bears and it’s decreasing their population. When polar bear population decreases, other animal populations will rise and the animal chain will change. We should not let global warming take over our species and destroy the animal chain. Polar bears are one of the many animals affected and if there are too many animals affected, the whole animal chain will fall apart. Research shows that, even if steps are taken to reduce emissions now, gases already in the atmosphere will continue to heat up the earth for another 40 to 50 years. Scientific statistics indicate they may suffer extinction by year 2100. We still have many years to make a
However, the earth has slowly gotten warmer, which means the ice melts earlier and freezes later. This gives the polar bears less time to hunt. It is harder for mother polar bears to have cubs because the can’t feed them. Polar bears will be in big trouble with the earth keeps getting warmer. Without the ice, polar bears can’t hunt and they could become
Global Warming has had an enormous impact in several different ecosystems. From forests to the ocean, and especially to cold environments like the North Pole. The effects of global warming have been so bad that the ice have started to melt, and animals that need the ice to survive or other vital activities started to suffer. Animals like polar bears (Ursus maritimus) have been seen behaving in different ways, and all the evidence leads to global warming. There have been evidence of polar bears that drowned because of the lack of ice, but one of the most significant changes in their behavior is their way of hunting. Polar bears now have been seen hunting in land to satisfy their need of food. This lead to several questions, is this behavior
The planet is warming, ice is melting across the world, especially at the north and south poles. The rising temperatures seems to be melting glaciers and sea ice. Many artic animals use the sea ice to hunt and give birth. So many different animals depend on the sea ice for survival, such as polar bears, penguins, and walruses to name a few. Because of global warming the artic wild life is losing their homes and way of life.
Global warming is causing possible extinction in the Antarctic ocean by melting all the ice its raising water levels causing fishing grounds to flow colder water that other species may not be used to and can affect them badly, and leaving seals the live on the ice more of chance
Another point he makes is that Polar bears are getting scrawnier because the seal habitat has declined because global warming causes the ice to melt. This is false. A common fact global warming supporters forget to mention is that arctic and Antarctic snowfall replenish the ice each year. Polar bears and seals are more in danger of poaching than losing their habitat to global warming. Both species are on the endangered list. However, weighing anywhere between 775 to 1,200 pounds. Polar bears are still the largest species of bear living on the planet.
