Good news, guys — otters are returning to the Klang River!

Yup, the same river that's been infamous for years as one of Malaysia's most polluted waterways.

But now, the return of these adorable creatures could be a sign that things are finally changing for the better. And we have The Ocean Cleanup and Selangor Maritime Gateway to thank for that.

The Ocean Cleanup recently shared a video of otters spotted in the river — a promising sign that the water quality is improving.

The Ocean Cleanup, a global nonprofit tackling plastic pollution, deployed two Interceptor trash collectors in the Klang River — one in 2019 and another in 2021

Since then, these high-tech floating devices have removed over 3.2 million kilogrammes of trash. That's the equivalent of clearing out more than 10,000 Perodua Myvis' worth of rubbish!

Thanks to these efforts, the Klang River's ecosystem is slowly recovering. Otters are incredibly sensitive to pollution, so their return is a big deal — it means the water is getting cleaner and safer for wildlife.

Of course, there's still a long way to go, but this proves that change is possible.

Let's keep it that way by doing our part — disposing of waste properly and keeping our waterways clean.

Coldplay funded the construction and deployment of one of the Interceptors and used plastic waste from the Klang River to produce their latest vinyl records:
