The rising population has resulted in an increased demand on fish stocks, which are under stress; although the creation of the Funafuti Conservation Area has provided a fishing exclusion area to help sustain the fish population across the Funafuti lagoon. Population pressure on the resources of Funafuti and inadequate sanitation systems have resulted in pollution. The Waste Operations and Services Act of 2009 provides the legal framework for waste management and pollution control projects funded by the European Union directed at organic waste composting in eco-sanitation systems. The Environment Protection (Litter and Waste Control) Regulation 2013 is intended to improve the management of the importation of non-biodegradable materials. In Tuvalu plastic waste is a problem as much imported food and other commodities are supplied in plastic containers or packaging.
