Environmental impact Despite being marketed as "an energy-efficient, ecologically sensitive, land-conserving, low-polluting offshore city", the development has had significant negative environmental impact, with irreversible damage due to reclamation of ecologically sensitive coastal wetlands. The area within which Forest City lies is protected as an Environmentally Sensitive Area (ESA) Rank 1 area, where no development is allowed except for low-impact nature tourism, research and education. Chief to this designation are two areas of international ecological significance, the Tanjung Kupang intertidal
seagrass meadow, the largest of its kind in Malaysia, and the
Pulai River Mangrove Forest Reserve, designated as a wetland of international importance under the
Ramsar Convention. Reclamation began in January 2014 without the legally required Detailed Environmental Impact Assessment (DEIA). Residents from Kampung
Tanjung Kupang, a traditional fishing village, complained of reduced catches and other issues to the local and Johor State authorities to no avail. Malaysia had also not informed Singapore as required under their 2005
International Tribunal for the Law of the Sea–mediated agreement on reclamation works and other treaties. Singapore subsequently sent a diplomatic note in May 2014 to the
Malaysian Federal government requesting clarification on issues including: potential changes in water current speeds and the subsequent impact on navigational safety; possible erosion that might affect shoreline and
Malaysia–Singapore Second Link bridge infrastructure; and changes in water quality and morphology that might affect the coastal and marine environment and local fish farms. Following this and an accompanying outcry by international environmental watchdogs, the Environment Ministry sent a request for the DEIA to Country Garden on 6 June 2014, and issued a stop-work order on 17 June 2014, although it was reported that work continued despite the stop-work order. Country Garden subsequently announced that it was downsizing the project by a third and dividing it into four islands, although there was subsequent evidence that some of these measures were not implemented, including photographs where silt curtains were absent and of buffer zones that were less than 100m (as opposed to the agreed 300m).
Safety considerations Cracks began to appear in the Show Gallery, hotel buildings and nearby roads shortly after construction. The rapid pace of development following land reclamation without allowing sufficient time for the soil to settle and stabilise was cited as a likely cause. A building consultant observed that the reclaimed land was sinking and warned that the subsidence was expected to continue. ==Coverage and criticism==
