Environmental Issues of the Mackenzie Valley Pipeline Project.
The Mackenzie Valley Pipeline is a project proposed in 1970s with a purpose to transport natural gas and oil from the Beaufort Sea through Northwest Territories to tie into gas pipelines in northern Alberta. The project was scarped because of Thomas Berger's report which stated how the project would have a negative effect on environment and First Nation communities. After many year the land claims have been settled by the Aboriginal groups, but the environmental issues still exist today. One of the main issues is wildlife and how they will react to the pipeline. The pipeline runs through areas such as Kendall Island Migration Bird Sanctuary and other unprotected, but highly wildlife populated areas and will disturb animal habitats. Construction noise will affect the migration patterns of some species and the pipeline itself will act as a physical barrier above ground. Increased animal death is a very large concern, as curious animals are attracted to the construction noise and could be seen as problematic to the workers and therefore killed. The construction of the pipeline will interrupt water flow in lakes, rivers and even groundwater. This could change the quality of the water as well as disturb fish habitats. The disruption of groundwater flow can have an impact on the source of freshwater for waterways, but also be a trigger for erosion. The construction and use of the pipeline will raise greenhouse gas emissions in the NWT by at least 44 percent. Additionally, every year gas from the Mackenzie valley pipeline is burned, 25 million tons of CO2 will be emitted into the atmosphere causing global warming and large impacts on the environment
