数据表明，每人每天平均产生1.5公斤的垃圾。我们该如何处理这些垃圾呢？3R原则可以帮助我们。
Reduce减量化：减少不必要的消耗是保护环境的一种方式。看看成堆的外卖和快递包裹。我们真的需要如此多的包装吗？
Reuse再利用：世界上没有真正的垃圾，只有放错了地方的资源。你有没有去过跳蚤市场？发挥你的想象力，给一些“垃圾”带去新的生命吧。
Recycle再循环：一些垃圾可以转变成新的产品，所以要将其仔细分类。比如你的旧手机、旧杂志等，不要随意丢弃它们。拿到回收点，它们会获得新的价值。
看看周围，在我们日常生活中有哪些垃圾可以减量？哪些可以再利用？哪些可以再循环？每个人都能为保护环境出一份力。不只为了我们自己，也为了整个地球，让我们养成环保的好习惯，过快乐健康的生活。
