Energy Consumption : Household Heating

This study directly relates to my question because it provides two consequences of climate change; sea ice reduction and increase in primary productivity due to the warming of the oceans. As to how it is effecting the polar bears reproduction, results show that in one subpopulation's body size, condition, and reproductive success increased or remained stable due to an increase their prey ringed seals, due to increase in productivity. In the other subpopulation, there was lower recruitment and an overall smaller body size of the bears with a location that had fewer periods of reduced ice and no significant increase in productivity. This suggests that climate change can improve reproductive success of polar bears in some locations and decrease in

Global warming is the recent and ongoing rise of temperature on a global scale. Over the past century, the Earth's average temperature has risen 1.4°F (Carlowicz, 2010). Global warming is the effect of an excessive amount of greenhouse gases in the atmosphere. Greenhouse gasses trap heat from escaping back into space to keep the Earth from freezing, this is called the Greenhouse Effect. An excessive amount of greenhouse gases in the atmosphere trap too much heat, thus, causing Earth's temperature to rise.

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

Canada 's unique geographical location and its harsh weather conditions, requires extra use of energy to keep the houses warm."[Moreover we have to transport goods, to far of places including territories, therefore as a result we use extensive amount of fuel for the transportation purposes]" (Energy, Statistic Canada). "[Per capita consumption of electric power in Canada was 16,473.16 kWh in 2011. In 2010 Canada’s average energy consumption was, 41% from petroleum, 31% from natural gas and 1% consumption from coal]" (Energy, Statistic Canada). We produce about 65 million metric tons of coal each year but, consume 50 percent of it and the remaining is exported to many countries of Asia, including Japan and South Korea (ILC 2007, CGW4UA, U2, L10, P 24). As per Statistic Canada our total consumption of energy was divided as: "34% of the energy was consumed by transportation. Residential and Agricultural sector consumed 20%. Manufacturing 19%, whereas mining, oil and gas extractions consumed 10% of the energy. Moreover 74% of the total energy consumed was in the provinces of Ontario, Alberta and Quebec. Canada produces 3 million barrels of oil, and consumes 2.2 million of it" (Energy, Statistic Canada). The rest is exported to the United States for sale. Furthermore Canada has cross border trade of electricity with the US and it exports "30 billion kWh of electricity" (ILC 2007, CGW4UA, U2, L10, P 25).

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

With the ever rising global temperatures, melting ice caps, and constant warnings about global warming, it is no wonder that the animals inhabiting the artic regions around the world are now suffering a decline in their habitat as well as their livelihood. Such is the case with the Polar Bears who may soon be gone in a scant few years.

Decades of research suggest that sea-levels are rising, and will continue to rise as a result of climate change. This rise will have the most immediate and significant impact on

effects of global warming. In the first place, Canadians are capable of saving energy from

The polar bear lives up in the Arctic region where global warming and climate change are melting the ice caps that the bears thrive on. They use the ice as a platform from hunting and rest. The random pocket holes in the ice, where the seals pop up at, is where the polar bear catches its prey. With this reduction of ice, “the abundance of seals, and increases the amount of energy and time needed for hunting, leaving less energy for reproduction” (Endangered Species and Habitats).

The concerns about the ever rising sea levels, melting ice caps, and constant warnings about global warming making their way into everyday news and our lives, it is no surprise that bears inhabiting the arctic regions are now suffering as a result. The extent of the damage done to the Polar Bears may mean they'll soon be gone in a scant few years.

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.

Polar bears mostly live in the costal ice or north pole Because of thick clear fur that protects it body from the extreme temperatures of the snow and the ice cold water. The polar bear is a carnivore that eats’ seals, walrus, seabird but humans and global warming are killing them. The polar bear run across the ice or put it head in a hold to get food for it babies or for itself to eat. When they make babies they put them in hole and when they grow up they can live up to 20-30 years in their life. But most of them are gone because of environmental problems and global warming because of us humans doing bad things to the world. So the area threaten animal which causes them to might go extinct which is bad for the animal.

Polar bears are the most known animals for the impacts of climate change on species. Global warming has been most prominent in the Arctic, and this trend is expected to continue. Their dependence on sea ice makes them highly vulnerable to a changing climate. Polar bears greatly rely on the sea ice environment for traveling, hunting, mating, resting, and in some areas, maternal dens (WWF). Specifically, they depend heavily on sea ice-dependent prey such as seals. Additionally, their long generation time and low reproductive rate may limit their ability to adapt to changes in the environment. Every time people breathe or burn something, oxygen in the air is converted to carbon dioxide. The carbon dioxide is used by plants to breathe and is converted back to oxygen, creating a cycle. If there is an increase in oxygen burning, for example, burning a lot of coal or oil to generate electricity or run cars, and cut down trees, the amount of carbon dioxide in the air is increased. This makes the air thicker and warms up the earth. The amount of warming is only a few degrees but it is enough to disturb the fragile balance of nature, which in turn will melt the polar ice, raise sea levels, cause violent hurricanes and endanger species such as polar bears. The polar bears are just one example of endangered animals because of the high demand of human need for energy which is acquired by burning fossil fuels.

Climate change is increasing; it is a serious problem that threatens our future. Scientists warn that it is changing our health, economy and communities, if we do not aggressively curb it now; the results will likely be disastrous (The Natural Resources Defence Council, 2015). Energy consumption contributes to climate change, so it must be reduced. For the purposes of this essay, I will explore three main areas where reducing energy consumption could contribute to solving the problem of climate change: meat and dairy consumption, work and food waste.
