won't solve it but it will help. start with the schools take out the junk food vending machines provide it with healthy options. secondly change the cafeteria from frozen re-heated crap with made from scratch healthy dishes. this isn't some idea where it sounds good but could not possibly be effective. i live in British Columbia, Canada where at my school this has already happened the vending machines are all healthy the cafe is a scratch kitchen and to help make it affordable the students run the kitchen (and is a great opportunity for anyone hoping to pursue a career in the restaurant businesses) this won't solve the problem and will cost the government some money but being able to give children at least one good healthy meal can make all the difference.
