there (will be) serious air pollution if people use more and more cars.为什么用will be?
条件状语从句,主将从现,从句if people use,用了一般现在时,主句必须用一般将来时,表示将来会有严重的空气污染
另外 there be结构是表示存在有的句式,即哪里有,be可以有时态的变化,一般将来时,be变为将来时的will be

if 引导的条件状语从句 “主将从现”，即主句用将来时，从句用一般现在时
望采纳O(∩_∩)O

if条件句

表示将来，所以用将来时。
祝你学习进步，更上一层楼！ (*^__^*)
不明白的再问哟，请及时采纳，多谢！

there be 的一般将来时态，根据后边的if 条件状语从句判断。
满意请采纳，谢谢！
