Each weekday， more than 30 million students in Canada eat meals in school cafeterias． And when lunch is over， they fill the rubbish cans with uneaten food．

    More than ＄1 billion worth of food is wasted every year． Wasted food is wasted money．It's also a missed chance to feed hungry people．And it's had for the environment：farming， packing， and transporting food produces greenhouse﹣gas emissions（温室气体排放）． They pollute the air．

    Schools have developed ways to cut back on（减少） waste． Making lunch period longer helps． It gives kids time to eat everything on their plates． Many schools follow government rules that say students must take a certain number of healthy things at mealtime． Those rules help kids get a better meal． But they can lead to more waste． That's why schools in Canada set up something called share tables．Students put untouched food on the table． A student who wants the food can take it． There are rules to make sure the food is safe． Food that isn't taken from the table is served another day．

    Students also waste food because they don't like how it tastes． Cook Sam wants to change that． He works with a program called Cooks in Schools． He helps dining hall workers develop dishes kids enjoy．

    You can fight food waste too． At the store， look for "ugly" produce．Fruits and vegetables with bad shapes are still delicious， but they are often not noticed． At home， read safety labels（标签）． If a label says "best before"， the food is still safe to eat for a little while after the date． If the label says "use by"， the food is no longer safe after the date．
