Mudflats at Tiaozini, Jiangsu province, have silted up. A fishing boat is seen in the distance. A major land reclamation project at Tiaozini threatens the survival of the IUCN critically endangered spoon-billed sandpiper and other species. Before 2020, another 59,950 hectares are planned to be reclaimed at Tiaozini and nearby -- a total area that amounts to more than ten times the size of Manhattan.
