FORT MCMURRAY, CANADA - APRIL 27: A soccer ball made of canned foods by elementary school students, as part of a fundraiser for the local food bank, on April 27th, 2015 in Fort McMurray, Canada. As oil prices dropped in late 2014, the Fort McMurray food bank saw a 74% increase in demand for their services. Fort McMurray is currently coping with an economic downturn as a result of low oil prices and most of the layoffs have been impacting the transient workforce. Canada's oil and gas industry is expected to lose 37% of its revenues in 2015. (Photo by Ian Willms/Getty Images)
