星期天，我在爸爸的幫助下，上網查了一下西安三月份前半個月的空氣質量，一查，讓我大吃一驚，我發現其中國重度污染有六天，輕度污染有兩天，中度污染有七天。
原來我們生活在這樣的環境下，我問爸爸：“霧霾和沙塵對人體有什么危害嗎?”爸爸和我查閱了一下網上的資料，原來，霧霾和沙塵的危害非常大，霧霾會導致傳染病擴散和多種疾病發生，給人體健康帶來較大的危害。沙塵也會危害到人們的身體健康，還給人類出行帶來很大的不便。
我又查了一下造成霧霾和沙塵的原因，原來大氣空氣氣壓低，空氣不流動是主要因素，空氣不流動是空氣中的微小顆粒聚集在一起，漂浮在空中，由于地面灰塵大，空氣溫度低，地面的人和車輛是灰塵攪動起來……沙塵是一種風雨沙的相互作用的危害性天氣現象，它的形成與地球溫室效應、植被破壞、物種滅絕、氣候異常等有著不可分割的關系。他還分為沙塵暴、浮塵、強沙塵……
我想我們不應該無節制開采自然資源，不應該隨意砍伐樹木，有車的人盡量少開車，多做公交車和騎自行車，綠色出行。燈泡盡量用節能燈，少開空調，大家要給街道多灑水。不隨地亂扔垃圾，多植樹造林，保護我們的地球。
