The ocean's new frontier

The sea has huge resources and great potential for economic growth, employment and innovation. At the same time, they are considered indispensable to address many of the global challenges facing the planet, from food security and climate change to the delivery of energy, natural resources and medical services. But they are abused, polluted, and face climate change
The ocean economy includes industries such as shipping, fishery, offshore wind power generation, marine biotechnology, etc. It is also natural assets and ecosystems such as fish, waterway, carbon dioxide absorption. In 2010, the global economy contributed 1.5 trillion dollars of employment and hired 31 million people. Overseas oil and gas account for one-third of the total added value of the marine industry, followed by ocean and coastal tourism, marine equipment and harbors. The largest employer is an industrial fishery fishery, accounting for over one-third of the total. Ocean and coastal tourism account for almost a quarter. Based on these forecasts, based on the "regular business" from 2010 to 2030, the marine economy can more than triple the contribution to the global value and can adopt it in 2030 I will. 40 million people
This "blue economy" is expanding rapidly, but the ocean is under pressure. As anthropogenic carbon emissions increase over time, the oceans absorb large quantities of carbon dioxide and lead to acidification. In addition, increases in seawater temperature and sea level, changes in ocean current (and atmospheric airflow), biodiversity and habitat loss, changes in composition and movement patterns of fish species, and an increase in the frequency of serious weather events I will. Future prospects for marine development are further exacerbated by agricultural outflows and land pollution such as overfishing and depleted fish species in many parts of the world
Therefore, responsible sustainable development approaches are needed to maximize the potential of the oceans. The new OECD report "Marine Economy 2030" promotes international cooperation in marine science and technology, strengthens integrated ocean management, improves the statistical and methodological infrastructure at the national and international level, and 4 One suggestion is shown. More a foresightable capacity in the marine industry

Ocean - New Frontier is exploring how human society pushes the limits of the ocean, trying to utilize all its resources, minerals, fisheries, fuel, and genetic material. New discoveries, technologies, national strategies, and ecological demands continue to redefine the boundaries of the ocean. Increasing the dependence on human dependence on marine resources, blurring the boundary between the continent and the sea
In most cases, when we think about the ocean, I think it is an infinite resource; the final boundary that has not yet been developed. Too many people take too much time because the ocean belongs to everyone and does not belong to anyone. Decades of abuse and neglect drive this fragile, already debilitating thing, and most of our lives are in danger of collapse. There is increasing evidence that the loss of marine natural capital by unsustainable use is rapidly eroding the resource base on which ecological security, economic activity and social welfare depend. Most maritime fisheries are being overfished or approaching overfishing. The proportion of fisheries classified as overfishing has continued to increase since the 1970's, currently accounts for about one-third of the global catch, causing massive unemployment, poverty, food shortage, protein shortage . In the past 30 years, the world has lost about half of the coral reefs.
"Frontier's way of thinking" is not what we need. When it comes to the ocean, we can not call economic growth opportunities infinit
