On Tuesday , President Donald Trump signed an executive order to vivify and expedite two multi - billion - dollar undercover pipelines that would snake rock oil through US land to pith of the petroleum industry .
One is thecontentious$3.8 billion Dakota Access word of mouth , which would shuttle petroleum more than 1,100 miles , from North Dakota ’s Bakkan oil bailiwick to holding armored combat vehicle in Patoka , Illinois .
The other is the Keystone XL grapevine — a new section of the survive Keystone Pipeline scheme , which begin in the Alberta , Canada petroleum sands , also called tar sands ( use of either termis controversial ) , and end in Patoka as well as points in Texas along the Gulf of Mexico . The XL section , which could be its buildersas much as $ 10 billion , is part establish and would move declamatory volume of oil in less time by abridge the route and burying larger - diam pipes .

Proponents of the word of mouth say it will lessen dependence on strange crude oil while make chore and grow domestic industriousness . However , many Americans , and primarily Native Americans , are furiousabout Trump ’s latest executive ordering .
Barack Obama killed the Keystone XL pipeline in November 2015 , express it would n’t have helped lower gas cost orcreate that many problem . He also say the long - term contribution to mood change — maybe more than22 billion metrical tons of carbon befoulment , according to Scientific American — was n’t worth the loss of America ’s global leadership on fight emissions that exacerbate global warming .
" If we ’re going to prevent big parts of this Earth from becoming inhabitable , if not inhospitable [ … ] we have to keep some fogy fuels in the ground , " Obama say .

Trump ’s televised revivification of Keystone XL did n’t mentionits steep environmental costs , include the 54,000 square miles ( 140,000 square kilometre ) of pristine Alberta wilderness that may be industrialized to feast it .
" We ’re not saying the project is good or spoiled . We ’re just saying the exfoliation and rigor of what ’s happening in Alberta will make your spine tingle , " Robert Johnson , a former Business Insider newspaperwoman , wroteafter flying over the Canadian fossil oil sands in May 2012 .
Keep scrolling to see an updated interpretation of Johnson ’s photo essay , which designate Canadian oil mining — a process in which tar - ladened guts is dug from the soil and the oil is separated through a lengthy and messy process .

This floor has been updated to include details about in situ extraction , which is different from the minelaying method acting and makes up about half of Canada oil sands production .
To get a look at the oil sand mine , we rented this Cessna 172 , which the airplane pilot was allow to fetch down to 1,000 feet . Through the open windowpane we could see what really goes on in one of the most controversial places on the major planet .

About 20 % of Alberta ’s oil sand deposits can be reached with aerofoil mining . The other 80 % is ripe for the in situ method , which has a less visible step compared to mining . The snag in method of product today is about 50/50 .

So far , only a small portion of Alberta ’s fossil oil sands are developed . And Canada expect any minelaying operation to rectify the area . But there are cost to expanding in situ output .

In situ origin still impacts wildlife , such as caribou herd , and it takes more push — and mother more glasshouse gases — to extract oil color compared to mining . critic also say restore a while of developed soil to its aboriginal experimental condition is not realistic .

With the excavation method , once the crude oil is draw in from the sand , it ’s shuttled to an ' upgrader ' like Suncor ’s here on the Athabasca River — one of the sites where the oil colour from the Amandine Aurore Lucie Dupin is convert into synthetic crude .
