IntroductionPresident Roosevelt's words ring sadly true in a time of grave difficulty. The wonder and bounty of fish as a sustainable food source diminishes more and more every day. The Food and Agriculture Organization of the United Nations reports that “An estimated 15 to 20 percent of all animal proteins come from aquatic animals” and “of the 30 countries most dependent on fish as protein source, all but four are in the developing world” which shows that fish is a key source of protein for many people in the global community (FOA, 2014). This statistic gives weight to the harm to society due to the loss of sustainability of fish if it were to lose its primary food source. Fish is high in protein and low in fat and cholesterol, which are important for daily dietary needs. Fish has become an increasingly popular choice for protein, and the United States ranks third in the world in seafood consumption (FOA 2014). As the planet's population increases and resources develop, fish have become scarce as a food source, even though the Earth is largely covered in water. Why? To better understand the change in the availability and potential of fish as food, it is hoped that this paper can provide insight into how we are losing a great treasure from the oceans and other waterways. The causes of the decline The causes of the decline of fish as a sustainable resource the food source comes from multiple outlets. Humans have continued to grow and evolve. In our natural growth progression, we have continued to inhabit places outside of previous boundaries, changing the landscape causing habitat loss for land and marine animals. Humans bring new species into areas that become invasive. We've also changed the food dynamic... middle of paper... http://www.bbc.co.uk/news/world-asia-pacific-12709791>• Jackson, Jeremy BC , et al. “Historical Overfishing and the Recent Collapse of Coastal Ecosystems.” science 293.5530 (2001): 629-637.• Lohmeyer, Adam M., and James E.
