SDG 14 · Life Below Water

More than a third of the world's fish stocks are overfished.

Eco Heroes turns that fact into a story an 8-year-old can hold onto: Glasses to Another World, book 14 of 17 in the SDG Library.

The target, in plain language

What the UN actually promised

Target 14.4

By 2020, effectively regulate harvesting and end overfishing, illegal, unreported and unregulated fishing and destructive fishing practices…

The 2020 deadline passed. The good news: ocean protection now covers more than 10 per cent of the ocean, and a new treaty for the high seas has entered into force.

Target 14.1 asks the world to prevent and significantly reduce marine pollution of all kinds, especially from land, including the litter that washes from our streets into the sea.

Why it matters

The number behind the story

35.5%
of assessed fish stocks are overfished Only 64.5 per cent are within biologically sustainable levels (latest global assessment).
