In the first picture, a boy and a girl are planting trees together, contributing their humble share to preserve the eco-system from an early age. And we see a green city without smog in the next picture, where high-rise buildings peek out from thick branches. These scenes are really encouraging.  

The invaluable lesson we can draw from the pictures above is that we can improve the air quality we breathe everyday by taking concrete steps to advance the Green City movement. There is no arguing that smog is a problem that we can no longer ignore. But the question is how to fight it and what to do now. Instead of merely tracking smog indicators and complaining about PM2.5 levels on social media, we can make a difference collectively by doing simple things in our daily lives, such as making environmental-friendly choices while shopping and opting for public transportation when travelling. Smog is not built in a day and cannot be attributed to a single factor, so the process to get rid of it would also take time and require persistent efforts from both the public and the government. 

It may seem no account whether one person maintain a sustainable lifestyle, but we can gather support from all walks of life and create the synergy, then it will be only a matter of time that smog becomes a rare occurrence and is gradually forgotten as a dated concept. 

参考译文：

     第一幅图中，一对男孩和女孩正在合作种树，从小就为保护生态系统尽绵薄之力。因此，我们在另一幅图中看到一座没有雾霾的绿色城市，高楼大厦从浓浓的绿荫中探出头来。这些场景真的令人鼓舞。

      我们能从图中得到的宝贵教训是，我们可以通过切实的行动，推动绿色城市运动，帮助提升空气质量。毋庸置疑，雾霾是我们不能再忽视的问题。但关键在于如何抗击它，现在能做什么。与其仅仅是在社交媒体上跟踪雾霾指数，抱怨PM2.5水平，我们可以通过在日常生活中的一些小事集体做出改变，比如说买东西时选择环保商品，外出时选择公共交通。正如雾霾不是一天形成的，也无法归因于一个来源，消除雾霾的过程也会消耗时间，并需要来自公众和政府的持续努力。

      也许一个人是否维持可持续的生活方式无足轻重，但我们可以聚集社会各界的支持，形成合力，然后随着时间流逝雾霾定会变得少见并逐渐成为一个过时的概念。
