One-fifth of Mekong river fish species face extinction, report says

BANGKOK, March 4 (Reuters) – Unsustainable development threatens the health and diverse fish populations of the Mekong river, with one-fifth of fish species in Southeast Asia’s main artery facing extinction, a report by conservation groups said on Monday.
The Mekong, stretching nearly 5,000 km (3,000 miles) from the Tibetan Plateau to the South China Sea, is a farming and fishing lifeline for tens of millions of people in China, Laos, Myanmar, Thailand, Cambodia and Vietnam.
