  1. We now realize that the Earth has limited resources (which, if they are wasted, you put everyone in danger.) a.same (too large, the simpler the better remember and just sounds awkward)

b.and if you waste them it puts everyone in danger ( the sentence does not uses you, if you see a sentence that uses YOU first then goes with YOU, but in this case, in the first part of the sentence goes with WE not with YOU)

c.and wasting it will be perilous (it is for singular, so this answer is using a wrong pronoun)

d.and it puts everyone in danger to waste them (what puts who in danger?, again it goes with singular not plural)

e.that we waste at our own peril.
(this sentence avoids all the aforementioned errors, so you can either eliminated the other answers or you can see that, in this case, the sentence does not have any error because we are talking in plural so all the rest of the sentence should be in plural)
ANSWER-E

There’s no error. (B) breaks the idiom “more A than B”, (C) breaks the idiom “presented as” (presented for is wrong), (D) breaks the comparison, and (E) breaks the comparison/parallel structure.

(A) mixes active and passive voices. (B) no antecedent for the pronoun “it”. (C) pronoun error (resources->it). (D) modifier error (danger to waste) among other problems.
