Overfishing is decimating marine populations from "summary" of The 6th Extinction by Elizabeth Kolbert
The oceans are vast and seemingly inexhaustible, but human activities have taken a toll on marine populations. Overfishing, the practice of catching fish at a rate faster than they can reproduce, is causing widespread devastation in the world's oceans. As fishing fleets have become more efficient and technology has advanced, the ability to harvest fish has increased dramatically. This has led to a situation where many species are being caught at unsustainable levels, leading to population declines and in some cases, collapse. The consequences of overfishing are far-reaching. Not only are individual species at risk, but entire ecosystems are being disrupted. Fish play a crucial role in marine food webs, and their decline can have cascading effects on other species. For example, when a predator like sharks or tuna is overfished, it can lead to an explosion in the population of their prey, which in turn can have negative impacts on other species. This can create a domino effect that ultimately alters the entire ecosystem. ...
