According to the article "The Global footprint of fisheries" by Julie Cohen, 55% of the world's waters are covered by fisheries. The Earth is composed of at least 70% water, so being able to cover 55% of that is staggeringly impressive (human greed is the best motivation afterall). UC Santa Barbara teamed up with prominent scientific figures such as Global Fishing Watch, National Geographic, Dalhousie University,Skytruth, Google, and Stanford University in order to accurately illuminate the world's global fishery net.
