Coastal construction threaten mangrove forest that protects Vietnam's biggest city

Coastal construction is putting Vietnam’s Can Gio mangrove forest at risk, a natural buffer between Ho Chi Minh City and rising seas. Mangroves protect the city of 10 million by absorbing carbon, sheltering marine life, and strengthening the coastline, but scientists warn that development tied to a new seaside city, a major port, roads, bridges and a 14-km (9-mile) sea-crossing route to Vung Tau could disrupt water flows that sustain the ecosystem. About 80% of Ho Chi Minh City’s area is vulnerable to flooding, and the government estimates higher seawater costs it around $57 million annually. Can Gio was replanted after near-death during the Vietnam War and became a UNESCO biosphere reserve in 2000.
