Technological advancements in fishing methods, such as the introduction of larger nets and reduced mesh sizes, have resulted in significant reductions in fish stocks. An apt analogy here might be trying to catch jellybeans with a butterfly net - you're going to get a whole lot more jellybeans than you would butterflies! Smaller mesh sizes mean even young, small fish get caught, reducing the chances for fish populations to replenish.

Example: Bottom trawling, where large nets scrape the sea floor, has led not only to overfishing but also extensive damage to marine habitats. Imagine if a giant net scraped across your neighborhood - chaos, right?

Despite these issues, fishing can be managed in a way that promotes sustainability. Think of it like learning to share a limited supply of pizza at a party - if everyone takes too much at once, there's nothing left for later!

The EU's Common Fisheries Policy (CFP) is a key example of efforts to manage fisheries sustainably. Much like when a school updates its rules to ensure a better learning environment, the CFP underwent recent changes in 2014 to improve its effectiveness.
