377 - How does overfishing impact marine ecosystems?

Imagine a big web with many connected threads. Overfishing is like breaking some of those threads. When too many fish are caught, it affects the whole ocean ecosystem.

Here's how:

1. Fewer fish: With fewer fish, the ocean's balance is disrupted.
2. Less food for other animals: Fish are a food source for many animals like dolphins, seals, and birds.
3. Harm to plants and habitats: Some fish help keep seaweed and ocean plants under control, so if they disappear, it can harm these habitats.
4. Changes in ocean water quality: With fewer fish to eat certain organisms, the water quality can get worse.

Overfishing is like taking out a key piece of a big puzzle, making it difficult for the ocean ecosystem to function properly.
