Modern magic is designed to amaze and entertain. It's proper word is legerdemain (not sure if the spelling is correct). It means to fool you. ALL magic you see on TV and in person consists of routines of TRICKS. All tricks are like puzzles & they have an answer.
This person you saw is an entertainer, and probably a very good one. He cannot save world hunger - no one can.
Even most mentalism is magic. I have a friend who tells his audience, before he starts his hsow, that he has absolutely no psychic abilities and everything he dies is a trick. At the end of his show, no one believes him, because he messes with their minds and he is very good. It's still just magic. It's still just tricks and entertainment.
Whether it's Chris Angel or one of the other current hit magicians, none of it is real.
Your desire to end world hunger shows great compassion and is honorable. I would recommend that you step down to a smaller scale and just do what you can to help people. You cannot save the world, but you can touch the lives of many by just volunteering doing something you enjoy and/or contributing monies to valid charaties that only take a small percentage of donations, if any at all, to operate the charity. such an effort could include volunteering to do a tour of duty in a country of starving people, or helping financially to keep a few of the children healthy and alive. You could also spread the word and encourage others to do the same.
Good luck in your ventures. Magic is a facinating hobby! I have been an amateur magician for over 40 years. I love watching good performers and I don't even try to figure out how they do it. It's good entertainment.
