Questions & Answers about La facciata sarà rovinata dall'inquinamento.
Why do we use sarà here instead of è?
This sentence is in the future tense ("will be"). In the passive voice, the auxiliary verb essere (to be) carries the tense. So, we use the third-person future form sarà combined with the past participle to mean "will be ruined".
Why does rovinata end in -a?
Why is "by the pollution" translated with dall'?
In the passive voice, the agent (the person or thing actually doing the action) is always introduced by the preposition da (by). Here, it combines with the definite article l' (because inquinamento starts with a vowel) to form the combined word dall'.
