[Post 1401] Is Your Food Safe? Inside Thailand’s Toxic River Crisis | Insight

Summary

In late 2025, images of deformed fish caught in Thailand’s rivers made headlines around the world. The strange lesions on the fish have been linked to rare earth mines upstream.

With limited cross-border enforcement and growing geopolitical competition over critical minerals, can the contamination be stopped before the damage becomes irreversible?
