Large amount of leftovers are discarded everyday. Some environmentalists upload pictures of leftovers on social media to create public awareness. A charity collects leftovers and redistribute them for the needy. A designer uses leftovers to grow plants. As our landfills reach their capacities, how much time do we have to sort out our leftovers?丟棄廚餘情況嚴重，有環保人士拍下食客浪費食物的情景，然後放上社交網站，要引起網民反思。環保業商人把工商業廚餘製成禽畜飼料出售。慈善機構回收食肆的剩餘食物，統一處理後再分發給有需要人士。有設計師教導城市人利用它來種植。環保署推行廚餘回收計劃，成效受環保團體質疑。三個堆填區將會飽和，我們還有多少時間去討論怎樣處理廚餘呢？
