我們生活的地球正遭受著嚴重的空氣污染。工廠排放的廢氣、燃燒的垃圾、汽車的尾氣等都是污染大氣的.禍源。它們時刻侵襲著我們的呼吸道和肺，使呼吸系統的發病率逐年上升。
當空氣輕微污染時，人體吸入的空氣可以由鼻腔里的鼻毛除去部分灰塵，再由鼻腔里的黏液和各類支氣管里的黏液將灰塵粘連住。氣管和支氣管內的纖毛有幾千萬根，它們每秒約擺動12次，像“清潔工”一樣從下向上推掃呼吸道里的黏液，直至咽喉部，再通過咳嗽咳出體外。
當空氣嚴重污染時，呼吸道的凈化作用將降低，甚至完全喪失。在這種情況下，呼吸道和肺易受病菌的侵襲而患各種疾病。
由于種種原因，空氣污染還在加劇。如果不能解決空氣污染的問題，恐怕真有一天，人類只能帶著口罩生活。
