Oxfam's GROW campaign is rolling out five easy ways for people who care about hunger to help. Trying any of these principles, and encouraging your friends and family to as well, could make a real impact and help address the problem of millions of people that still don’t have enough food on their plates. Do you practice any of these principles? Have any advice for how the rest of us can improve our daily food habits?
