Questions & Answers about Если бы мы жили без пластика, мы бы спасли природу.
Why are both verbs (жили and спасли) in the past tense if the sentence is talking about a general or future situation?
Why does the first half use an imperfective verb (жили) but the second half uses a perfective verb (спасли)?
The choice depends on the specific meaning of each action. "Living without plastic" is an ongoing, continuous state, so it uses the imperfective жили. "Saving nature" focuses on a successfully completed result, so it uses the perfective спасли.
Does the second бы have to go exactly between мы and спасли?
Why does the word пластик change to пластика here?
The preposition без (without) always requires the noun that follows it to be in the Genitive case. Since пластик is a masculine noun ending in a consonant, it takes the standard Genitive ending -а.
