Walmart and Sam's Club are kicking off their sixth annual "Fight Hunger. Spark Change." campaign. Running from April 22 to May 20, the campaign looks to raise awareness about the ongoing hunger struggle many currently are going through, and also help combat the issue, the company said. "As we go into our sixth year of the 'Fight Hunger. Spark Change.' campaign, it's exciting to approach the 1 billion mark in terms of charitable meals secured by Feeding America over the life of the program," Kathleen McLaughlin, chief sustainability officer at Walmart said. "Food insecurity continues to affect communities across the United States. Working with Feeding America, our customers, members, associates and suppliers, Walmart, and Sam's Club aim to be part of the solution." In partnership with Feeding America and 18 other large suppliers, the Bentonville, Ark.-based company also is inviting its 150 million weekly shoppers to help achieve Feeding America's goal of securing 1 billion meals.
