4]. Our knowledge of cold-water coral diversity is limited, with many new reefs still being discovered. The biggest threat to deep-sea coral reefs comes from bottom trawling activities. 2]. ■ Intertidal Habitats and Deltas Food and bait collection (including molluscs and seaweeds) and human trampling have substantially depleted many of the organisms in these habitats. In the United States, the rocky intertidal zone has undergone major transformation in the last few decades. Similar trends have been observed elsewhere in the world.

Indirect Drivers of Change in Marine and Coastal Ecosystems Demand, Fish Prices, and Shifting Food Preferences Marine products are in demand as a luxury food, as a subsistence food source for many coastal communities, and as feed for aquaculture and livestock. Per capita consumption of fish is increasing rapidly—total fish consumption has declined somewhat in developed countries, while it has nearly doubled in the developing world since 1973 [CT 8, Main Message #9]. 3]. 4]. 8].
