To add to this these methods need vast amounts of energy for extraction, causing the high extraction cost and with this also pollute greatly as the oil is extracted and so raise CO2 and other GHG emissions before the fuel is even burnt. Some of the environmental cost in these areas would be evident. The Canadian Tar Sands, Arctic and the marine ecosystems in the Gulf of Mexico are rich in biodiversity and pristine areas of wildlife and any spills of oil in these areas could be disastrous. The Arctic tundra is very sensitive to human interference and the Canadian Tar Sands is home to thousands of species of animals and is one of the largest bird migration centres in the world, millions of birds use this areas every year and groundwater depletion is another major problem as groundwater needs to be pumped out during mining operations otherwise flooding will occur. Reducing ground water levels will have consequences on the wider ecosystem and it will affect wetlands.
Global warming is the result of greenhouse gases. The accumulation of greenhouse gases in the atmosphere leads to the alteration of weather patterns. Because temperature and moisture are essential to the way organisms and ecosystems develop, climate change impacts can be a major threat to mammals. Researchers estimate that global warming has the potential to severely alter 35% of the world’s existing habitats. Climate change may cause species loss as high has 20% in the arctic habitats
The Globe is losing its Cool Global Warming Melissa Moran University of Phoenix Axia collage Professors name SCI 275 October 21, 2009 There are many reasons for the change in the climate. Climate change also known as global warming is the change in the average temperature of the earth surface, and the change in wind and precipitation. Global warming is caused by releasing fossil fuels into the atmosphere. Many factors such as human activity and greenhouse gas emissions contribute to global warming. Global warming also has natural causes though they are often down-played in the media.
Such pressure has resulted in 'environmental issues', ranging from global warming and eutrophication, to the depletion of natural resources and an increase in the number of landfill sites. A distinction must be drawn between 'anthropogenically created' environmental issues, and 'natural' ones. The extinction of most of the dinosaurs more than 65 million years ago was not caused by man, but rather an entirely natural disaster, perhaps a meteor or extreme tectonic activity. It is difficult to apply any man-made ethic to situations that are not man-made, so for the purpose of this essay, 'environmental issues' will be taken to be current issues actively cause by human beings. During the last few decades, many thinkers from different disciplines have been searching for a new ethic to confront environmental ethics issues with – an ‘environmental ethic’.
One major threat is that coral reefs are under huge stress due to the impact that human activities are having and in fact already 1/5 of the world’s coral reefs are so damaged that they are beyond repair. The increase of average global temperatures is leading to an increased rate of ice cap melting. This is due to global warming, making a global threat to all ecosystems including the coral reef. The reason for this is that the melting of the ice caps releases more fresh water into the oceans, reducing salinity making sea level rise. Due to sea level rising coral reefs are getting destroyed, as they cannot survive in water above 25m.
It is also a problem that does not have many possible solutions, causing it to be the most detrimental to harp seals. Economically the elimination of harp seal hunting will affect the lives of commercial hunters and those who purchase the pelts. This issue is not solely negative as the Canadian Government plans to compensate the hunters with new professional training. Lastly this issue could eventually lead to the extinction of a
Modernity may cease with global warming as half the biggest companies are oil companies, and oil is the essence of life. Deforestation and the effects of global warming on our forests and trees are far-reaching and quite evident. All our planets physical features are changing rapidly. And McKibben repeats himself on purpose to get his point across: the planet we knew is no more, we live on a new, more complex and harsher
Gore also asserts that global warming is caused by over population. Toxins and chemicals in the atmosphere impact each individual in the world. Because of the effects of global warming, the strength of hurricanes can change easily and cause an enormous amount of
Many worry about the negative consequences Global Warming may have on our Earth. It is believed that there will be detremental effects from sea to land. A rise in water levels causing the icecaps to melt. Melting icecaps would then release methane another greenhouse gas. The oceans salt water would mix with freshwater and CO2 would get absorbed into the oceans causing disabling effects on our waters food chain.
Both a nuclear holocaust and a zombie apocalypse can kill millions of people, but if I were to decide which among the two would be more horrific, I would go for zombie apocalypse. When I think of nuclear holocaust, I see it as some sort of explosion of a large bomb, strong and damaging enough to harm the entire universe and kill every living creature there is, all at the same time. Yes, reiterating it once again, being conscious of the fact
