Ocean shock big aquaculture bulldozes borneo – нежлоб -) electricity measurements units

Not long ago, the clearing had been home to mangroves, saltwater-loving trees that anchor a web of life stretching from fish larvae hatching in the cradle of their underwater roots to the hornbills squawking at their crown. Now the trees’ benevolent presence was gone, in their place a swath of stripped soil littered with felled trunks as gray as fossils.

The company is Sunlight Inno Seafood. electricity in human body wiki Owned by Cedric Wong King Ti, a Malaysian businessman known as “King Wong,” it has bulldozed swaths of mangroves in the Tombonuo’s homeland in northern Borneo to make space for plastic-lined ponds filled with millions of king prawns. The shrimp are destined to be fattened for three months, scooped up in nets, quick-frozen, packed into 40-foot refrigerated containers and loaded onto cargo ships bound for distant ports.

As the buildup of heat-trapping greenhouse gases causes the world’s oceans to warm, ecosystems that formed hundreds of thousands of years ago are being upended in less than a human lifespan. Across the planet, fish and other marine creatures are being forced into a desperate search for cooler waters. Even coral is on the move: Some Japanese reefs are expanding northward at up to nearly nine miles per year, researchers have found.

“If you ask me what is the No. 1 concern that I have on climate change effects on fisheries, it is on these tropical, developing countries,” said William Cheung, director of science at the Nippon Foundation-University of British Columbia Nereus Program. “The sheer speed of the change will make it that much harder for marine life to adapt.”

Coral reefs, as vital to tropical fish as trees are to birds, are becoming more vulnerable to a process called bleaching, which occurs when a spike in water temperatures causes coral to expel the algae that provide their kaleidoscopic colors, leaving them prone to starvation or disease. gas house pike frederick md Today, swaths of the once-psychedelic Great Barrier Reef in Australia have turned boneyard white and largely devoid of life.

Scientists fear a similar fate could await the Coral Triangle, a huge underwater wonderland east of Borneo endowed with a trove of biodiversity comparable to the rainforests of the Amazon Basin. Millions of people depend on its bounty to survive, a large share of them Malaysians, who eat an average of 125 pounds of fish each a year — more than double the world average.

Forty years ago, only 5 percent of the world’s fish production was farmed. After decades of rapid growth, aquaculture reached a tipping point in 2013, according to the U.N. Food and Agriculture Organization, when the amount the industry raised in cages, tanks and ponds outweighed the tonnage of freely swimming fish hauled from lakes, rivers and seas for people’s plates.

​In many respects, the industry has a good-news story to tell. Farmed salmon, for example, can convert feed into edible protein far more efficiently than cows or pigs, while producing fewer greenhouse gases. gas pains 6 weeks pregnant Now, almost all the salmon sold in restaurants and supermarkets is raised in captivity, with Norway, Chile and Scotland the biggest producers.

But this phenomenal expansion has come at a cost. The appetite for farmed species is so voracious, almost 20 percent of the annual catch from the world’s seas is ground into fishmeal, a nutrient-rich powder that forms the basis of the feeds used from salmon cages in Scottish lochs to shrimp ponds on Borneo. static electricity bill nye full episode Vast amounts of fish have been taken from poorer countries to feed species destined for the plates of wealthier consumers. In addition, shrimp farms, in particular, have made coastal communities in the tropics even more vulnerable by cutting down mangroves, their first line of defense against extreme weather and rising sea levels.

Since the mid-1970s, the aquaculture industry has led to the destruction of more than 1.3 million acres of mangroves spread across Indonesia, Thailand, Vietnam, India, Bangladesh, China, Brazil and Ecuador, according to a 2013 paper in the Bulletin of Marine Science. Untreated waste and epidemics of shrimp-killing diseases mean the gains can be short-lived: A study published this year identified more than half a million acres of abandoned shrimp ponds in Indonesia alone.

In 2013, representatives of Sunlight Seafood offered leaders of the Tombonuo and other indigenous communities a deal. In return for some of the land flanking the tidal creeks where their mangroves stood, locals recalled, the company would provide running water, electricity and much-needed employment for youths in the surrounding area, known as Pitas.

Earlier this month, Junz Wong, Sabah’s agriculture minister, toured the Sunlight Seafood farm and said the company had operated “quite professionally” and created nearly 400 jobs. On his Facebook page, Wong said he had rejected a company request to cut down an additional 1,000 acres of mangroves. “I told them NO,” he wrote. “No more destroying of mangroves.”

Irwin Wong is a manager at Oceandrive, a Malaysian seafood company that buys the sea cucumbers for export. He served as an adviser when Mapan Mapan started cultivating the creatures eight years ago in a 20-farmer pilot project backed by the local government. He says the scheme is harvesting wild sea cucumbers at a sustainable rate, but that even better management could help Borneo produce many more.

The beauty of these creatures is that, unlike farmed fish or prawns, they don’t require any feed apart from the nutrients they absorb from the sea. sgas belfast No mangroves have to be felled to culture them. Neither do they spew tons of fish waste or chemical pollutants. In fact, bivalves actually remove toxins from the water; a single oyster filters 50 gallons of seawater a day.

Yet even as the risks posed by climate change bring the potential of shellfish, seaweed and sea cucumbers into sharper focus, it is also putting them in danger. 2 chainz smoking on that gas As oceans absorb carbon dioxide released by burning fossil fuels, seawater is rapidly becoming more acidic. There is already evidence that acidification can make mussels’ shells more brittle, or weaken their grip on rocks, leaving them at greater risk of being swept away by advancing waves.

Life has been kind to the prize specimens at the Borneo Marine Research Institute: mammoth tropical fish known as giant grouper, which can weigh as much as a person, and in some cases have been swimming in spirals in silo-like tanks for almost 20 years. The only drama happens at feeding time. When fresh sardines hit the surface, the fish dart through the water with torpedo force.

Their wild relatives will have to work a lot harder to survive. In experiments to simulate the effects of more acidic waters, the institute has found that grouper — a staple in the Coral Triangle — find it harder to reproduce, and their young don’t develop properly. The findings have sharpened concerns about what climate change will mean for the region’s marine life, already struggling with plastic pollution, runoff from oil palm plantations, damage to reefs by dynamite fishing and the loss of mangroves.

Shek Qin, a research assistant, visits the busy fish-landing quay at Kota Kinabalu two nights a week to monitor catches of sharks and rays. static electricity human body causes In the early hours of a July morning, she picked up a newly landed shark by its tail, plonked it onto the dock and cheerfully inserted her forefinger into its mouth, peering inside to inspect the teeth — a trick for classifying a specimen more accurately, especially if fishermen have lopped off the fins.

Near the fence surrounding the Sunlight Seafood shrimp farm, villagers Bondien and Samayong moored their flotilla under some mangrove trees and cast lead-weighted hooks. Samayong’s daughter Ida remembered her grandfather regaling her with tales of the monster fish of his youth — notably, a ray he once caught that was bigger than his boat. But that day, nothing came to nibble.
