'Zerstören' (to destroy) is an inseparable verb. The prefix 'zer-' almost always indicates destruction, separation, or falling apart. When you see this prefix, you can often assume a negative or destructive meaning.

An earthquake completely destroyed the old bridge.
How do you recognize the meaning? Pay attention to the object of the verb. If it is a physical object (e.g., a house, a city), it is about material destruction. If it is an abstract concept (e.g., trust, a friendship), the immaterial meaning is intended.
Der Sturm zerstörte das Dach unseres Hauses.
The storm destroyed the roof of our house.
In the context of physical destruction, 'zerstören' (to destroy) is often used with buildings, cities, nature, or objects. Typical combinations are: 'ein Nest zerstören' (to destroy a nest), 'die Umwelt zerstören' (to destroy the environment), or 'Beweise zerstören' (to destroy evidence).

When it comes to immaterial things, 'zerstören' (to destroy) is often combined with feelings, relationships, or plans. Typical phrases are: 'eine Freundschaft zerstören' (to destroy a friendship), 'Hoffnungen zerstören' (to destroy hopes), or 'einen Ruf zerstören' (to destroy a reputation).

'erhalten' and 'zerstören' are clear opposites here. When you preserve something, you make sure that it remains and does not fall into decay. When you destroy something, it is damaged so severely that it is no longer usable or no longer exists. So the difference is: 'erhalten' preserves; 'zerstören' breaks or destroys something.
