If you're getting enough food to eat each day, consider yourself lucky. Many others, even in wealthy countries like Japan, routinely go hungry.

That was the lesson students from Tokyo YMCA International School learned Friday from the nonprofit group Second Harvest Japan, which distributes unused food to people who need it.

Kicking off a presentation at the school, whose students range from preschoolers to eighth-graders, Second Harvest CEO Charles McJilton told the students to think of the group as a "food bridge."
