Canadian Tar Sands:

Canadian Tar Sands Complex Extraction Process

Canadian Tar Sands:

Canadian Tar Sands Complex Extraction Process Remove Forest Cover

Canadian Tar Sands:

Canadian Tar Sands Boreal Forest Tar Sands

Canadian Tar Sands:

Canadian Tar Sands Complex Extraction Process Remove Forest Cover Dig up Soil (oily soil – tar sands)

Canadian Tar Sands:

Canadian Tar Sands Dig up and transport tar sands

Canadian Tar Sands:

Canadian Tar Sands Complex Extraction Process Remove Forest Cover Dig up Soil (oily soil – tar sands) Heat clean water

Canadian Tar Sands:

Canadian Tar Sands Heat clean water with natural gas 4 barrels of clean water are used to make 1 barrel of oil

Canadian Tar Sands:

Canadian Tar Sands Complex Extraction Process Remove Forest Cover Dig up Soil (oily soil – tar sands) Heat clean water Use hot water to separate soil from oil

Canadian Tar Sands:

Canadian Tar Sands Tar sands  oil

Canadian Tar Sands:

Canadian Tar Sands Complex Extraction Process Remove Forest Cover Dig up Soil (oily soil – tar sands) Heat clean water Use hot water to separate soil from oil Dispose of used dirty water in tailing ponds

Canadian Tar Sands:

Canadian Tar Sands Tailing Ponds

Canadian Tar Sands:

Canadian Tar Sands Complex Extraction Process Remove Forest Cover Dig up Soil (oily soil – tar sands) Heat clean water Use hot water to separate soil from oil Dispose of used dirty water in tailing ponds Ship oil to USA (pipeline)

Canadian Tar Sands:

Canadian Tar Sands Pipeline to the USA

Canadian Tar Sands:

Canadian Tar Sands Presently, Canada #1 supplier of oil to the USA Why ? Large Supply (2 nd largest in world) Reliable Stable weather social

Canadian Tar Sands:

Canadian Tar Sands Currently largest energy project on earth Disturbed area = 149 000 km 2

Canadian Tar Sands:

Canadian Tar Sands Currently largest energy project on earth Disturbed area = 149 000 km 2 ( Over 4 Taiwans !)

Canadian Tar Sands:

Canadian Tar Sands Significant impacts

Canadian Tar Sands:

Canadian Tar Sands Greenhouse gas emissions In one day the tar sands produce as much CO2 as 1.34 million cars

Canadian Tar Sands:

Canadian Tar Sands Destruction of Habitat

Canadian Tar Sands:

Canadian Tar Sands Impacts on Wildlife

Canadian Tar Sands:

Canadian Tar Sands Impacts on humans First Nations communities have higher cancer rates downstream of the tar sands
