如今，空气污染在许多城镇都是一个大问题。在天气不好的日子里，天空看起来灰蒙蒙的，我们外出时看不远。人们开始关注这个问题，因为它与我们的健康息息相关。
许多汽车和工厂产生有害气体，使空气变脏。这种气体停留在空气中，对生物有害。为了减少这种气体，一些城市增加了更多的公共汽车供人们乘坐。家庭也尽量少开车，选择更环保的出行方式。每一个小小的努力都能帮助空气变得更清新一点。
当空气变脏时，很多人，尤其是孩子和老人，经常咳嗽。这种不舒服的感觉告诉我们，我们现在需要净化空气。脏空气也会影响我们的日常生活，让我们不想在户外玩耍或做运动。如果我们共同努力，我们就能改变这种情况。我们可以告诉我们的家人和朋友加入到净化空气的行动中来。让我们继续做这些小事，我们很快就能呼吸到更清新的空气。
