Explanation

This question is a difficult question, and it mainly examines the understanding of the difficult sentence L74-79.

The forests and the orchards are the wellsprings of diversity. (The forests and the orchards are the wellsprings of diversity. Source.)

2. The attributive clause guided by that (that modifies diversity, acting as the object of the clause verb phrase return to):

A, B, and C return to diversity.( A, B, and C These scientists will return to the diversity brought by these forests and orchards for help.)

3. every time guides the adverbial clause of time, every time can be translated into when (every time)

A, B, and C return to diversity [every time] our society whittles the resilience in our fields and orchards down to its breaking point. (Whenever our land and orchards are overused to the point where we can no longer grow crops, scientists turn to the diversity of crops that forests and orchards bring.)
