厨余答案是厨余垃圾。

据统计，我们日常生活产生的垃圾中，最多的一项是厨余垃圾，竟然高达60%！

没错，就是人们吃的需求，所产生的垃圾最多。

当然，吃并没有错，但作为地球的一份子，无论为了地球的可持续发展，还是人类自己的健康，我们都有责任管理好自己产生的垃圾，让自己吃的更环保、更少负担。

因此，在《食物里的大世界》这个系列课的最后，我们一起来探讨一下“垃圾去哪儿了？

”垃圾的由来你知道吗？

在人类诞生之前，世界是没有垃圾的！

！最初，所有的东西都是地球物质循环的一部分，缓慢而有序的互相转化着。

即使在人类诞生以后很长一段时间，垃圾也没有成为亟待解决的问题，因为垃圾的总量并不是很大，自然可以自行消化。

海南蓝洋温泉国家森林公园内的露天垃圾场（2006年·新华社）这些垃圾不断的聚集，对地球的环境和其他生物产生了巨大影响。

在太平洋上，甚至出现了垃圾“大陆”。

垃圾减量的3R原则3R原则给了我们非常好的指导：Reduce 减少垃圾量，包括减少反复、过度包装，减少购买小包装食品等。

是我们要最先考量的原则。

Reuse 重复使用，包括拒绝一次性产品，通过修理、修补延长使用寿命，通过交换减少购买新商品。

Recycle循环利用，包括垃圾分类、资源回收。

想一想：《蒜你狠》中的废材花园，《大自然在唱歌》中的雨声筒制作，《果壳里的宇宙》中的自然手做，都符合3R中的哪个原则呢？

再想一想：在3R当中，你可以从哪几个方面入手来做垃圾减量呢？

这里，我们要给大家的一个提醒是：作为一个普通居民，最起码我们可以做到的是分类，这样不仅可以减少后期垃圾再处理的工作，让各类垃圾可以分门别类的被最优化的循环处理。

比如，完成分类的厨余垃圾，后期可以被集中做堆肥处理，使之可以产生新的价值。

但若是未经分类，既无法用作堆肥，也会污染原本可以分类回收的干净塑料等，导致只能填埋或焚烧。
