An on-line petition has been set up to try and change the way childrens school dinners are handled in the UK. It's a very worthy thing to sign even if you (like me) either didn't see, or didn't see much, of the series.
You're basically signing something that says:
"I believe kids need a healthy diet so we need to change school dinners to ban the junk and get fresh, nutritious meals back on the plate. I support the Feed Me Better campaign."
To do so please visit the campaigns website at http://www.feedmebetter.com/getinvolved/signexplain.php
EDIT: Over 80,000 people have already signed! I was number 81,096!!
