On the morning of Aug.15, a wrecked ship, longer than the Titanic, broke in two in Mauritian waters. The Japanese-owned bulk carrier, M.V. Wakashio, had rammed into the island nation’s coral reef barrier on July 25. In the weeks since the crash, it leaked almost 1,000 tonnes of fuel oil into the sea.
Oil-laden waves crashed on the shore, and greasy residue settled on coral reefs and slunk into the mangrove forests that clutch the eastern coast of the island. At least 30 kilometers (19 miles) of shoreline is heavily affected.
