Der folgende Text stammt aus einem Englischprojekt, welches wir vor wenigen Wochen präsentiert haben. Leider sind hier nur meine subtopics zu lesen. Aus diesem Grund ist der Text anfangs etwas verwirrend, da ein Ureinwohner über die Folgen der Holzindustrie, Ölsandindustrie und über das Verschwinden der Artenvielfalt redet. Ich hoffe ihr habt Spaß beim lesen.

Logging Industry

My grandfather used to tell me stories about our tribe and how we lived in consonance with nature.
He was very proud of the way we treat forests and animals.
I'm glad he does not know what happens with our nature nowadays.
However, back to the beginning.
I will explain to you what the forest means to the world and what occurs at these days.

In my country there are many forests and there is a tenth of the global forest cover located. The biggest forests areas are in Québec, Ontario and British Columbia.
Canada’s landscapes contain the temperate rainforest and the boreal forest and both are affected.
The boreal forest trends from the west (Yukon) to the east coast (New Foundland and Labrador) and encompasses 53 per cent of Canada’s total landmass.
It is Canada’s largest ecosystem and part of the green belt of northern forest circling the blue planet.
Unfortunately the woodland is in danger because the logging industry destroys our forests.
The forest administration of the provinces sell the right for forestry use.
Sometimes the agreements prescribe requirements as for instance reforestation. The mainstay of Canada's economy is the logging industry. Forest products are their largest export and that's the reason why they have to protect the forest.
Over 700 thousand hectares get cut down each year.

To rescue the forest we have to use the woodland sustainably. We also have to regard that the forest is home to many animal species. If we cut down too many trees the animals will lose their habitat and some of them even their life.
If we destroy the forests we will waste the chance to stop the climate change. In Canada only, the trees and ground accumulate circa 186 tons of carbon dioxide and that's why we have to stop deforestation.
Even if we plant new trees the forest will reduce the skills to fix the Co2 from the air. Young trees haven't got the same absorption capacity as old trees.
In addition, the forest becomes sensitive to the negative results of the climate change for example bush fires or insects attacks ( e.g. mountain pine beetle ).
According to "Global Forest Watch Canada" there are 62% of the boreal forest and 30% of the temperate rainforest intact.
I'm glad that environmental protection organizations were established e.g. "Greenpeace" or the "Western Canada Wilderness Committee", because otherwise the primeval forest would not exist anymore these days.

The faunal biodiversity disappears

Since the white people arrived many animal populations suffer. They changed the unspoiled nature and didn't take care of sustainability. Now, the situation is worsening and some animals are endangered.

The caribou lives in the boreal forest and needs special food availability .
At this time, the caribou is in danger, because the logging industry and the humans restrict their habitat.
The logging industry cut down the trees and disperse the herds. In addition, they destroy their habits and basic food recurrences.
Also, the residents and tourists bear the blame for their extinction, because during the winter skiing season skier fly to the tops of mountains with helicopters and scare the weak caribous.
Very often the caribous run away and burn fat that is essential for their life, because in the wintertime food is rare.
Sometimes pregnant females lose their unborn foetus.
Certainly, these things aren't the only significant factors for the declines. Also the overhunting, industrialization and the global warming are reasons for the decreasing population of caribous.
If we don't ensure that the caribou population recovers, Canada will lose one of the most recognized national symbols. The faunal biodiversity will decline once again.

Polar bear:

The polar bears are found in the Arctic.
They live along or close to the coast, on islands and mostly on sea ice. The artic sea ice is necessary, because it's their platform from which they hunt, live and breed. Sea ice is their basis of existence and supports a rich food chain. Plankton and micro-organisms are the basis of the foot chain that also nourishes seals. Seals are a basic food resource for the polar bears.
It is obvious that the ice and the richness of it is an advantage for the whole animal population. Sometimes polar bears have to swim long ways to hunt the seals. If the polar bears are exhausted they need ice floes to have a break and relax.
But sometimes polar bears drown, because the ice is too thin and can't carry their weight. That leads to death for a completely exhausted polar bear.
It should be added that the average weight of polar bears is 50 kg less than 20 years ago.
It's clear as daylight that the climate change destroys their basis of existence. With the climate change the ice melts and the population shrinks, because the mainstay food chain collapses.
The polar bears are also vulnerable based on the hunting of humans, the toxic pollution, the restricted habitats, the shrinking food availability and the oil exploration.
Experts predict that in the Hudson Bay will be no ice by 2080.
At this time the status of the polar bear is vulnerable due to the humans and their "great" behaviour.


Oil sands / tar sands

When I think of Alberta, I remember the snow covered mountains, the lucent blue lakes and the unspoiled conifer forests.
Now the reality is different because nature is destroyed by the bitumen production.
In the ground of Alberta are 170 billion barrels of degradable oil located. (One barrel=159liters)
Canada aims next to Saudi Arabia one of the biggest oil reserves.
That points out Canada’s worldwide roll in addition to the oil production.

I want to tell you more about the history of oil production in Alberta because it's an important part of the environmental pollution.

The tar sand extraction began with the second millennium because in the past it wasn't profitable.
With the technological development, the demand for oil and the high oil price began the tar sands extinction.
Seas get polluted, forests get lumbered and animals are chased away. Some areas are transformed into moonscapes with poison ponds and mountains of sulphur.
At this time 1,2 million barrels of oil are gained daily. One of the most dangerous facts is that the used water gets polluted.
For each liter of bitumen five liters of water are needed. The used water is tainted with heavy metal like quicksilver and is known to be a cancer causing substance.
Altogether the affected ponds are 130km² large and roughly 11 million liters of the poison water seep daily in the groundwater and near rivers.
It is well known that 200 km downstream in Fort Chipewyan is a disproportionate tendency of cancer.

The disadvantages of the production of tar sands :
the separation of oil and sand needs a lot of water
the production of vapour requires a huge amount of energy
water disposal is still a problem
subterranean ecological damage arise
losing forests and fenland
animals and humans become ill because of the poisonous water

To put it in a nutshell, the oil sands extraction destroys the entire boreal forest and fenland. It also influences the rivers and the natural landscapes. It's a debatable point whether the ecosystem will be able to recover or not.

Schöner Text :)
Ich mag die Einleitung mit dem Großvater und das Titelbild ist echt aussagekräftig. Einerseits möchte man lachen, weil die Bäume so lustig ausschauen, aber andererseits macht es echt deutlich, dass zu viele Bäume gefällt werden.
Ich hoffe, ihr habt dafür eine gute Note bekommen :)
