Essays on Polar Bear

The majority of scientists are in agreement that global warming is occurring and is caused by human activities over the last two hundred years or so. Global warming is caused by the build up in the atmosphere of gases such as methane, carbon dioxide, nitrous oxide and others which have been created by the burning of fossil fuels in order to produce electricity, and for use in industries and motor vehicles. Another contribution to global is the removal of vast areas of natural forest from the planet. . The majority of carbon dioxide exchange between the atmosphere and the earth ...

Abstract

This paper examines the case of Massachusetts v. Environmental Protection Agency, a 5-4 Supreme Court decision that combined the substantive, environmental law question of whether the Environmental Protection Agency erred in its initial decision not to regulate greenhouse gas emissions for motor vehicles with the procedural issue of whether states, cities, and environmental organizations had legal standing (defined as the right to use the courts as opposed to Congress to force governmental action) for the environmental claims at issue in the case. This paper begins with a brief overview of the political, legal, and cultural context for assessing the ...

1. Introduction Global warming consequences have been mainly focused on the impacts they have and will in the future have on the global human population. The less focus is on the impact on the animal and plant species that are even more vulnerable, since they cannot adapt to quick changes as humans can. They are not the main culprit for the climate changes and yet they will suffer the most. One of the animal species that is being threatened by the global climate change are also polar bears that inhabit the polar region. They are playing an important role ...

Introduction

Environmental adaptation is essential to the survival of any animal. In fact, this attribute helps organisms obtain nutrients, build homes, withstand extreme weather conditions, attach mates and enhance their safety (Nelson et al. 2008). With this in mind, it is worth appreciating the fact that polar and grizzly bears have different physical and behavioral characteristics due to environmental adaptation in spite of their species similarities. The polar bear is specially adapted to survive in the cold pole regions. Its body structure and genetic composition have substantially evolved to accommodate the low temperatures and harsh environmental conditions. Its behavioral attributes ...

Introduction

People are very privileged to witness and experience a profuse and diverse natural resources and wildlife on our planet. However, this abundance of natural resources comes with a big stewardship responsibility. For many years, people have known the moral obligation to conserve and guard the diversity of wildlife. Loss of different species is very common nowadays. This loss is brought by population growth, habitat fragmentation and loss, invasive disease and resource removal (IPCC, 2001). Scientists state that the world is now living the sixth vast extinction. Countless species are in jeopardy. For instance, in the United States, more than five-hundred ...

On 7th January 20011, USA today reported the upholding by a Washington District Judge of the 2008 decision by government scientists of the US Fish and Wildlife Service to include the ‘Polar Bear’ as threatened in the endangered species list. The Scientists had contended that polar bear’s existence was threatened because of widespread melting of ice, a vital part of the natural habitat of the bear, due to global warming. The Polar Bear has thus become the first animal to be declared “threatened” due to global warming under the “Endangered Species” Act. But why should anyone have any objections ...

Nature Is Our Mother Who are the culprits in letting this polar bear and its cub on a sheet of ice and snow in the middle of ice-cold ocean? The polar bears seem to be frightened and hanging dearly to the floating ice. Someone is responsible for them losing their carefree life. The polar bear illustration showing a mom bear and its cub caught my eye and prompted me to write the following assay on global warming. In glance looking at the picture, it is hard to imagine and think about global warming and its ramifications for the ...

National Park System Plan The Park system plan of Canada started in 1970s. The Park System Plan is aiming its goal to represent every national region within the national parks system. This approach has provided a policy framework for the development of the national parks. It also has it goal that has guided the expansion of Canada’s national parks system since its vision started in 1970s. When the system plan is complete, our future generations will be able to see and experience our country’s national parks its biophysical diversity. This is one of the National Park ...

ABSTRACT

At no other time in the history of the planet has the impact of human activity affected the natural order of the planet. Humans account for the increase in global warming. In turn, global warming occurring at such a rapid rate leaves scientists scrambling determining how the future looks for all living creatures including humans. Statistics exist today, and predictions exist for tomorrow. However, changes in the climate, chemical effects on the oceans, the air, and changes in the planet's ecosystems continue and the rapid increase in global warming are still unfolding affecting plants, animals, and people as discussed in ...

This video highlights the successes of John Downer in capturing animals specifically Polar Bears in their natural habitat from angles unknown to the human eye. He has emphasized on the point that covert observation helps reveal those sides of an animal which may not be revealed otherwise. Polar Bears in particular are found in an extreme environment coupled with their aggressive nature it is difficult to study their behavior; hence, Downer used spy cams to reach up close with these creatures and he has been successful in observing their behavior by being in a safe environment far away ...

A reality that has been always considered a hoax by many as they believe global warming is because of the changing nature of the Universe and how the planet rotates. Global Warming is real because while it could be naturally influenced, the concentrations of the greenhouse effect emmissions causes the rays of the Sun to remain on earth, further influencing climate. The dispute that rages over this issue is unresolved because “experts” have shown “proofs” (for and against) based on scientific data. Supporters of the non-existence of Global Warming, basically offer the arguments as that the climate has changed ...

- I do believe that polar bears are endangered as a species. The main reason for this is that their number or population is decreasing drastically. Moreover there is a threat to their species itself due to global warming. Wildlife is an extremely important part of the ecology and crucial for the purpose of maintaining environmental balance. In case of there being human intervention it leads to a disruption in the environment and in wildlife. The main impact of global warming on the community and culture is that it is leading to health issues and higher levels of pollution. Moreover as the ...

Introduction

Polar bears are a range of bears from the family Ursidae and genus Ursus that natively lie within the boundaries of the Arctic Circle which well includes the landmasses and surrounding seas around the Arctic Ocean . Considering the native geographical location where the polar bears reside, it can be safely assumed that these creatures live in a predominantly cold weather environment . In terms of general physical features, a male adult polar bear should weight somewhere around 770 to 1,500 lbs. ; a female adult on the other hand should be somewhere around half of this size . Polar bears are a sister specie of the ...

Introduction:

Thesis: Global warming has had a number of negative effects on the ecosystems around the world. This can be attributed to the changes that it has introduced. The hot seasons become hotter, the cold seasons are colder and when it does rain, it is in torrents. All these radical changes in our weather are leaving behind a trail of destruction, hunger and change in the ecosystem.

Major points:

The effect of climate change on ecosystems can be classified into two. The first is the effect on terrestrial ecosystems while the second is the effect on marine ecosystems. Some of the major points ...

Introduction

In the recent past, many scientists have provided evidence on how global warming that result from greenhouse gases may adversely affect the arctic regions (including tundra biome). These scientists argue that the excess abundant of greenhouse gases will cause global warming of the earth's climate in the near future. This global rise in temperature is more likely to damage the Antarctic and Arctic biome that than all other biome. This is because global warming is expected to shorten arctic tundra's winters and melt snow that covers permafrost. As a result of this, there will be flooding in many coastal areas. ...
