overfishing
1 the world faces a calamitous food crisis if we do not stop overfishing. according to
the united nations, about one billion people, mostly in developing countries, rely on
fish as their primary source of animal protein. what will they do when the fish run
out? that crisis could occur soon. while there will probably never be a time when we
do not have fish, there could come a time when we no longer have enough fish. the
cause of this fish shortage is overfishing. overfishing occurs \when more fish are
caught than the population can replace through natural reproduction,\ according to the
world wildlife foundation. once this occurs, the species is no longer \sustainable.\

Explanation:

The phrase "wreak havoc" is often used to describe causing significant destruction or chaos. In the context of overfishing (as per the passage), overfishing (when more fish are caught than can be replaced) would lead to something negative. "Cause vast destruction" aligns with the idea of "wreak havoc" in the context of the negative impacts of overfishing (like disrupting the balance of marine ecosystems etc., which can be seen as a form of vast destruction in the marine life context).

Answer:

cause vast destruction
