When you both will start a campaign against junk food in starting you will face a lot of difficulties because of the children love junk food & can't stop them from eating it but still if you carry the campaign further some or the other day you will definitely succeed & all the people including children too will support your idea & if you all want to make the campaign more effective you can take help of the parents because almost all of themĀ support this idea the most.

hope it helps:-)
