How can we encourage nations to come together to protect the high seas? Members of government, business, and advocacy joined Prospect’s Breakfast discussion supported by High Seas Alliance “Ever since I started talking about environmental issues—ocean, terrestrial, climate—there probably hasn’t been a year when I haven’t said ‘This is the most important year.’
But this really does feel like the defining year,” Zac Goldsmith told a recent Prospect roundtable. “It’s the year where we have the opportunity—I would say the responsibility—to demonstrate to a world increasingly anxious about the state of our planet that we are genuinely serious about addressing those challenges.” Fact of the day: If the Earth’s surface was smooth, the oceans would cover the entire surface by approximately 2700m (8800ft). □ □

What happens when you pull the plug on the Marianas Trench. Reddit user: Vinnytsia The Mariana Trench or Marianas Trench is the deepest part of the world's oceans.
It is located in the western Pacific Ocean, an average of 200 kilometers (124 mi) to the east of the Mariana Islands, in the Western Pacific East of Philippines. It is a crescent-shaped scar in the Earth's crust, and measures about 2,550 km (1,580 mi) long and 69 km (43 mi) wide on average. #TheDeep of #OurBluePlanet (approx scaled) □surface v v v v v v v v v v v v □deepest whale 2992m v v v □average ocean depth 3682m v v v v v… Pristine paradise to rubbish dump: the same Pacific island, 23 years apart. *****The oceans are much deeper than you imagined. Mapping Ocean Ecosystem Services. *****Healthy coral reefs are good for tourism – and tourism can be good for reefs. Tourism is one of the world’s largest industries, contributing trillions of dollars to the global economy and supporting the livelihoods of an estimated one in ten people worldwide.
Much of that tourism depends on the natural world—on beautiful landscapes and seascapes that visitors flock to in search of escape, a second wind, and a direct connection with nature itself. Coastal and marine tourism represents a significant share of the industry and is an important component of the growing, sustainable Blue Economy, supporting more than 6.5 million jobs—second only to industrial fishing.
With anticipated global growth rates of more than 3.5%, coastal and marine tourism is projected to be the largest value-adding segment of the ocean economy by 2030, at 26%. Furthermore, mangroves and seagrass meadows are excellent at absorbing and storing carbon, reducing harmful emissions that cause climate change. Clearly, nature contributes enormous value to tourism and other industries. Share Written by. The deep-sea is being divided up for mining. What does this mean for marine biodiversity?

Ecological Marine Units Explorer (Esri) Global Fishing Watch (interactive map) EU proposes total commercial fishing ban on Atlantic sea bass. The European commission has proposed closures on commercial fishing for sea bass in the Atlantic and whiting in the waters west of Scotland from next year, in order to prevent a collapse in fish stocks.
The total allowable catch (TAC) for cod in the Celtic Sea will also be cut by 68% under the plan, while sole quotas in the Irish Sea will be trimmed by a hefty 82%. The move, to cut sea bass catches from 570 tonnes a year to zero, follows what the EU calls “very alarming” advice from fisheries scientists, who found that numbers had fallen below “safe biological limits”.
The same was true for Celtic cod, although cod from the North Sea which makes up a much higher percentage of British catches is in a healthier state and will be unaffected. “Celtic Sea cod could collapse,” without the proposed limits, one EU official said. “There is a reason why scientists are recommending such harsh proposals,” the source added.
