Boreal Forests Historically:
Boreal forests are coniferous forests located in the northern regions of the world, however they are still south of the tundra biome. The boreal forest biome is also known as taiga and is almost exclusively found in Canada and northern Europe. Boreal forests is the largest biome found in Canada consisting of nearly 60% of the nations land mass. The Taiga began forming as the most recent ice age came to an end. As the glaciers receded from the shift in climate the boreal forests began to form. The Taiga is known for its abundance of wild animals. The bison roam freely along side the worlds smallest carnivore the Least Weasel, and they have the worlds largest population of caribou, bears, and wolves. The Canadian Taiga is also home to the worlds largest freshwater supply containing more than 1,000,000 freshwater lakes. Historically, boreal forests have not been a desirable place for large populations to inhabit, however civilizations have been depending on this habitat for its abundant resources(Osbourne,2013)(The Past, 2011)(Forest Ethics, 2013).

Current Human Impacts:

The Boreal forests have been suffering due to human impact in the past decades. While mining in Canada is vital to the economy providing one in every forty six Canadians with a job, it is detrimental to the forests and ultimately their own livelihood(Mining Facts and Figures,2013). Mining you have to move large amount of soils in order to get to the minerals you are looking for which is resulting in major deforestation. Logging in itself is cutting down trees, since 1975 loggers have cut down 65 million acres of trees(Forest Ethics, 2013). This logging alone is contributing half of the amount of California’s greenhouse gas emissions. Oil and Sand Oil extracting has harsh effects on the surrounding areas. While extracting sand oil 420 square km of land has been disturbed while only 65 square kilometers of that land are under reclamation(Yeh,2010). Canada extracts 13.7 billion cubic feet of natural gas per day. While Canada has an abundance of natural gas available the means of getting this resource is damaging to the surrounding environment(Natural Gas, 2013). To get natural gas out they have to drill wells into the ground and lay pipelines through the forests damaging ecosystems along the way(Extraction,2011). 
Canada has many dams for hydroelectric energy, but by building these dams they are affecting both the aquatic life and the life that lives near the river in order to survive(Environmental Impacts of Damms,2013). Due to the change of habitat from industrializing boreal forests there has been a drastic rise in white tail deer populations. As white tail deer populations continue to rise the wolf population grew as well. The increased wolf population directly correlates with an declining caribou population as the wolves encounters with caribou grew accordingly. Canada is being hit hard by global warming. The loss of proper climate for boreal forests leads to deciduous plants out competing the native conifers. Global warming also increases the risk of forest fires which is a further release of greenhouse gases to compound the problem even more(Kasischke, 1995).

Future Prospects for Boreal Forests:

There are countless ways that people in North America can help preserve Canadian boreal forests. First and foremost we can help establish protected areas and regions designated for sustainable usage. The sustainable usage would include: sustainable timber harvesting, less mining, and less fossil fuel extraction. Another great way to help preserve boreal forests is to try and reduce greenhouse gases.  One of the more simple ways of doing this is to drive a car with low emissions or not to drive at all. However, if Canada is able to reduce logging by one half it would eliminate as much greenhouse gas as if they were to take all the cars in Canada off of the road completely (Forest Ethics,2013). The reduction of greenhouse gases is a vital way we can help try and preserve the climate needed for the boreal forest to survive..the forest can change to more sustainable usage and less natural resource depletion. People need to also begin reducing the their impact around the world on climate change in order to preserve the Canadian boreal forest and many other biomes around the world.

How can we improve human impacts?

There are countless ways that people in North America can do to help preserve Canadian boreal forests. First and foremost we can help establish protected areas and areas designated for sustainable usage. The sustainable usage would include: sustainable timber harvesting, less mining, and less fossil fuel extraction. Another great way to help preserve boreal forests is to try and reduce greenhouse gases.  One of the more simple way of doing this is to drive a car with low emissions or not to drive at all.

The reduction of greenhouse gases is a vital way we can help try and preserve the climate needed for the boreal forest to survive. If Canada is able to reduce logging by one half it will reduce green house gas just as much as if they take all the cars of Canada off of the road completely(Forest Ethics,2013).the forest can change to more sustainable usage and less natural resource depletion. People need to also begin reducing the their impact around the world on climate change in order to preserve the Canadian boreal forest and many other biomes around the world.
