    Too Good To Go, an app operating in the UK, allows users to order leftover food at a discount from restaurants, according to the website. The goal is to help cut food waste.

    Users simply log in, pick a restaurant, pay through the app and then pick up their food at a set time—usually around closing or after peak meal times. Orders through the app cost between 2 British pounds ($2.60) to 3.80 British pounds (about $5). Users aren't able to pick the food items, but they get an idea of the type of food that will be available, according to Business Green.

    Users also have the option to give meals to people in need by donating 1 British pound or more through the app. More than l, l00 meals have been donated so far.

    To ensure the entire experience is super eco-friendly. Too Good To Go provides recyclable takeout packaging to participating restaurants.

    Restaurants using the app make extra money by selling food what would otherwisehave been throw away. And Too Good To Go itself makes money by taking a fee from participating restaurants on each sale.

    Founded in Denmark last year. Too Good To Go launched this year in the UK and is expanding to other countries. The app is available in Brighton, Birmingham, Manchester and Leeds, and will be in London later this month.

    “Food waste just seems like one of the dumbest(愚蠢) problems we have in this world,” co-founder James Crummie told Business Green. “The restaurant industry is wasting about 600,000 tonnes of food each year, and in the UK alone there are one million people on emergency food parcels from food banks. Why do we have these two massive social issues that are completely connected, yet there is not much going on to address them?”

    Too Good To Go has already helped cut a significant amount of waste. So far, the app has saved 600 meals from landfills in the UK, reports Business Green.

                                                                                                                                         生命之芯  李雪峰
        ①庭院的上空是一架纵纵横横的葡萄藤。初春时节,昏睡的葡萄藤醒了,它们先是睁开一粒粒紫红色看似惺忪的叶芽。不久,叶子便很快毛茸茸地伸展开了。它们很快就把庭院里的阳光剪得支离破碎斑斑驳驳,不半月,院子的上空就一片摇曳的苍翠,连一片金黄阳光也漏不下来。清风徐徐地一摇,几片碎碎的阳光偶尔从叶缝间掉落下来,但那是稍纵即逝的,像梦的碎片一样。
         ②我是十分喜爱这些张张扬扬的葡萄叶子的。清晨推窗一望,绿叶田田,满眼碧绿的饱满苍翠,让人感觉到了新一天的爽朗和清新。
        ③暮秋时节,满藤的叶子都已枯黄了,飒飒秋风一吹,便不停有三三两两的叶子从藤架上飘飘扬扬地凋落下来,落在庭院里、墙角和台阶上,像一只只再也不能飞的蝴蝶。这时,素爱清爽的妻子便不得不时时清扫那些落叶。但那落叶总像扫不尽似的,往往清晨刚刚扫过,但中午或傍晚时就又落了厚厚一层,有时一天扫了五遍,但还总是扫不净,仿佛你一转身它就又落下了。
        ④妻子也想了许多的办法,费尽了周折,院子里却落叶依旧,这让妻子又气恼又无奈。这情景往往一直要到落雪时才能结束。
        ⑤去年的中秋,满架的葡萄又变紫了。剪摘葡萄时,妻子不是挑紫透的先摘,把那些没有熟透的葡萄串子留着,而是一次全早早摘了,不论有没有熟透,摘得一串不留。妻子说,葡萄摘尽了,叶子落得就快,就不用像往年那样总是扫叶子了。
        ⑥果如妻子所说的那样,葡萄摘下后三四天,满架的叶子一下子就黄了,然后开始汹涌地凋落,一夜的工夫,庭院里就落了厚厚的一层,那些叶子显得十分憔悴,有的叶脉还青着,只是叶缘黄卷了一些,但却早早地凋落了。
        ⑦不到半月,葡萄藤上的叶子竟全落尽了,只剩下那些灰黑老藤和那些褐色的新条在庭院上空寂寂地缱绻着。偶尔飞来三两只鸟雀,怔怔地栖落在上面,然后啁啾几声就怏怏地飞走了。
        ⑧难道作物也有它们自己的灵魂吗?它们在泥土和风雨中生长,它们萌芽、抽叶、开花,全都是为了自己的果实,果实是它们生命的灯芯,一旦果实夭折了,它们的生命也就夭折了;一旦果实夭折了,它们的岁月也就黯淡了,无论这世界还有多么美好,无论岁月还有多么漫长,但它们却已走到了自己生命的秋天里。
        ⑨果实或许就是作物们的梦想,或许就是作物们生命的纯粹使命,或许就是作物们的灵魂,过早丢失了自己的果实,作物们生命的秋天就提前来临了。
        ⑩坐在静静的葡萄架下,仰望那一簇一簇摇曳的绿叶,我对一切都充满了敬意,无论是生命的,还是被我们视为非生命的,无论是一粒青青的葡萄,还是我们脚下的一粒泥土……
        ⑪一切都是有着自己的梦想和灵魂的。
