You could help by not calling them "beggars". If you are concerned that money would be used for something that you object to, buy them something to eat, or maybe some warm clothing. It is quite common for homeless people to wear shoes whose soles are falling off. If you don't want to give money at all, or have none to spare, then stop to introduce yourself, ask their name then offer to shake their hands. My shaking that hand which society deems as unworthy of being shaken, you may very well have saved a human life.
