Is the future of the supermarket looking bleak? Some seem to think so. According to consumer marketing firm RetailNet Group, grocery stores will soon be faced with an uphill battle. Food retailers could see the impact as soon as 2015, as population growth slows and the influential baby boomer segment becomes an elderly generation.

Additionally, younger, more affluent customers, especially those born after 1985, may be the first ones to turn primarily to online grocery shopping in lieu of physical visits to the supermarket. Some grocers are responding to this concern by launching initiatives for kids in an attempt to create a rapport with future generations of shoppers.

Call me antiquated, but I kind of like the physical act of strolling down the produce aisle, even squeezing avocados to make sure they're ripe. It's hard to imagine a future free of grocery stores. Could you see yourself shopping for food exclusively online?
