​Food for Trash at Mexico City Barter Market

A new barter market in Mexico City is helping residents trade their trash for food in an effort to reduce the mountain of waste produced by the megacity. Mexico City's huge, infamous Bordo Poniente landfill site was receiving 12,600 tons of waste a day, which is more than the weight of the Eiffel Tower, before it was shut down in December 2011. Although the landfill is no longer in operation, the city keeps churning out tons of trash.

   The local government has since launched several measures to reduce the waste created by the 20 million people who call the city home. The Mercado de Trueque began in March of 2012 and has proven to be an instant hit with residents. Jose Luis Aranda is one of thousands of locals who are now making regular visits to the market held once a month in the city's Chapultepec Park. Along with his housemates, Aranda brings along glass, plastic, and cardboard waste, which is separated and weighed. He is then given vouchers, which can be exchanged at a nearby farmers' market.

   The vendors at the market hail from local farms, adding the benefit of attracting shoppers to locally produced food. For Aranda, it's not just about buying vegetables to eat. He also picks up baby lettuce plants, which he plans to grow at home and sell at the market when he visits again. If he does, it would bring the city's plan full circle, essentially turning trash into food.

以物易物或以物换物，顾名思义，就是指用自己已有的物品或服务与别人交换，以换取别人的物品或服务，是一种现有贸易模式出现之前已有的交易方式。早在人类会使用货币作买卖之前，人类已经懂得以物易物。以物换物不同于买卖，并没有使用任何金钱作交易的工具，所以以物易物不一定是一场等价交换。现今，这类交易模式依然存在，通常出现在因特网上，例如分类广告网站。（数据源：维基百科）

墨西哥市易货市场拿食物跟你换垃圾

墨西哥市一间新易货市场正在帮助居民拿垃圾换取食物，以致力于减少这座大城市所制造出堆积如山的废物。墨西哥市臭名远播的博尔多波尼安特垃圾掩埋场在 2011 年12 月关闭前，每天都要收集超过 12,600 吨的垃圾，这比艾菲尔铁塔的重量还重。虽然这座垃圾掩埋场已不再营运了，但墨西哥市还是不断地制造出大量的垃圾。

自从掩埋场关闭以来，当地政府已推出ㄧ些措施，以期能减少全市 2,000 万市民所制造出的垃圾。Mercado de Trueque 易货市集从 2012年 3 月开办，立刻就证实了这个构想在居民之间已经一炮而红。荷西‧路易斯‧阿兰达是目前上千名固定会造访该市集的当地民众之一，该市集每月会在墨西哥市的查普尔特佩克公园举办ㄧ次。阿兰达会和室友ㄧ起拿着玻璃、塑料及纸板类的垃圾到市集，将这些废物分类并秤重。接着他能获得ㄧ些消费券，并拿这些消费券前往附近的农民市场换取商品。

市集里的摊贩来自当地农场，增添了吸引采购者购买当地生产食品的好处。对于阿兰达来说，去农市并不只是单单去买要吃的菜而已。他也买了莴苣幼苗，打算要在自己家里耕种，往后再度造访农市时带去贩卖。假如他真那么做，那他就能使市政府的方案更加完整，实质地将垃圾变成了食物。
