Скачать или смотреть Why Fish Are Shrinking — And Why That’s a Problem

Fish are shrinking—and the implications reach far beyond the ocean. Scientists report that in some species, adult size has decreased by 15–30% over the past few decades. This video explores why it’s happening and why it matters:

1. Warming oceans: Rising waters mean less dissolved oxygen, forcing fish to stay smaller to survive.

2. Overfishing: Size-selective harvesting promotes evolutionary shifts toward earlier maturity and smaller size.

3. Ecosystem disruption: Smaller fish reduce food web stability—impacting predators, coral reefs, and marine biodiversity.

4. Human toll: Around 3 billion people rely on fish as their main protein source. Shrinking fish threatens food security and livelihoods.

This is more than a biological phenomenon—it’s a warning signal about the resilience of marine life and the systems we depend on.
