english: Oil sands -- or rather, I should say tar sands -- oil sands is a PR-created term so that the oil companies wouldn't be trying to promote something that sounds like a sticky tar-like substance that's the world's dirtiest oil.
non_english: Oliezanden -- of liever teerzanden -- ‘oliezanden’ is een P.R.-term, zodat het niet lijkt alsof oliemaatschappijen die kleverige, teerachtige substantie promoten die ‘s werelds smerigste olie is.
