Think about all the people you know, not just friends, but acquaintances as well, people who you can meet and remember a little about them. Maybe not their birthday, but their profession, an idea of their family situation. I would say this would cover at least 100 people in your life. Now imagine if these 100 people were the only people. This would mean you would know 1 person who is starving. You would know 25 who are without cell phones, 23 don’t have shelter.
If you saw a few people suffering, would you not help them? Would you not give that starving person a sandwich, give one of those 23 a place to sleep on your couch, or maybe even join them under the stars on a nice night. Would you not try to do something to help them?
If every person in the world gave one meal to someone who is starving, we could greatly change the world. If we gave books to schools that are without supplies, we could greatly change illiteracy. Challenge your students to look into charities that reach out to people, and do something to help them. If they are able to donate, that would be great, if they can only promote the charities, that is also wonderful. But if there were only 100 people in the world, you would know people who are suffering.
