The sentence presents the problem and solution structure.
The textual structure known as "problem and solution" is used when a text or sentence presents a problem and how it can or should be solved.
We can see this kind of structure in the sentence shown in the question above, because this sentence shows that for the fishing industry not to suffer (suffering = problem) it is necessary to create measures that slow down the growth of algae in the bay (solution).
We can classify the other types of textual structure as follows:
- Chronological: Presents facts that happened on successive dates.
- Compare and Contrast: Displays the similarities and differences between two or more elements.
- Sequential: Displays events that happened successively.
