Since thousands of years, the human race has been developing cultural skills and technological capabilities that support its struggle for survival and lead to dominance over all other species. Since about a century, the exponential growth of knowledge, technology, industry and population (see Fig. 1.1) has reached a scale where man modifies biosphere to an extent, that living conditions on the whole planet earth start to change significantly. Resources that had been abundant are becoming scarce within decades. We have arrived in the Anthropocene [1] where man has a significant impact on the basic living conditions of the biosphere of the whole planet. A continuation of this growth rate will unavoidably reach its natural limits where resources vanish; the biosphere will change more rapidly than the ability of organisms and ecosystems to accommodate, and contaminations will endanger living. When such a condition is reached, it is likely that our human civilization will collapse and human population will diminish rapidly. Historic examples demonstrated that drought, hunger, wars and epidemics were typical endpoints of drastic environmental changes and overpopulation. While historic examples mostly affected only individual towns, islands, countries or indigenous nations, the limits of growth this time affect the whole planet and there is no “new world” to which our civilization can migrate. Recent research has proven that the era of a new biological mass extinction has already started [2] and it can be assumed that finally also our species will be affected.
Global Atlas of Marine Fisheries: A critical appraisal of catches and ecosystem impacts

Until now, there has been only one source of data on global fishery catches: information reported to the Food and Agriculture Organization of the United Nations by member countries. An extensive, ten-year study conducted by The Sea Around Us Project of the University of British Columbia shows that this catch data is fundamentally misleading. Many countries underreport the amount of fish caught (some by as much as 500%), while others such as China significantly overreport their catches. The Global Atlas of Marine Fisheries is the first and only book to provide accurate, country-by-country fishery data. This groundbreaking information has been gathered from independent sources by the world’s foremost fisheries experts, and edited by Daniel Pauly and Dirk Zeller of the Sea Around Us Project. The Atlas includes one-page reports on 273 countries and their territories, plus fourteen topical global chapters. National reports describe the state of the country's fishery, by sector; the policies, politics, and social factors affecting it; and potential solutions. The global chapters address cross-cutting issues, from the economics of fisheries to the impacts of mariculture. Extensive maps and graphics offer attractive and accessible visual representations. While it has long been clear that the world’s oceans are in trouble, the lack of reliable data on fishery catches has obscured the scale, and nuances, of the crisis. The atlas shows that, globally, catches have declined rapidly since the 1980s, signaling an even more critical situation than previously understood. The Global Atlas of Marine Fisheries provides a comprehensive picture of our current predicament and steps that can be taken to ease it. For researchers, students, fishery managers, professionals in the fishing industry, and all others concerned with the status of the world’s fisheries, the Atlas will be an indispensable resource.
