RT Report T1 Ecological Interactions between Tropical Coastal Ecosystems: UNEP Regional Seas Reports and Studies No. 73 A1 United Nations Environment Programme, A2 Birkeland, Charles K1 ecosystem YR 1986 FD 1986 LK https://wedocs.unep.org/handle/20.500.11822/11882 UL https://wedocs.unep.org/handle/20.500.11822/11882 NO 11891, Coastal ecosystems have been of particular importance to tropical Pacific Islanders because islanders have always depended upon coastal marine resources for at least 90% of their animal protein.
