Conservation groups and scientists worry that China’s push to boost its harvest of krill -- a shrimp-like creature used for aquaculture feed and human supplements -- may leave Antarctica’s whales, seals and penguins struggling to survive.
China is one of several nations, including Norway, Korea and Chile, harvesting krill with massive factory ships dragging miles-long trawl nets through the productive cold waters of the Southern Ocean. The krill is quickly frozen and into processed into pellets for aquaculture and livestock operations, fish bait, and high-value “nutraceuticals” such as omega-3 dietary supplements.
China’s leaders say they want a seven-fold increase in krill production, according to a recent report in the state-owned China Daily newspaper.
A Dutch team is developing clever waders that enthusiasts can wear to find not only the ideal location to fish, but to collect key hydrological data for scientists. Of most use to both groups would be waders that sensed water temperature. Anglers know this influences where fish go in a river and, for researchers, it betrays details about the movement of water in that river and its chemistry. "We need more data from more streams than we could possibly monitor with our sensor networks," explained Rolf Hut from Delft University of Technology. "Wouldn't it be nice if we had citizens walking around in the water, interested in temperature because they want to know where the fish are, and at the same time providing us with the information we can use for our research?" The data would be collected by a simple temperature probe in the wader boot. This would then travel up a wire to a Bluetooth device above the waist to be passed to a phone in a dry pocket. The angler could use the information straightaway to decide where to stand in the river and cast their fly, while the scientists would receive the details back at the lab over the cell network for later analysis.
The Smith River is one of the most pristine, beautiful rivers in the U.S. and the only undammed river in California. To discover the Smith is an unforgettable experience. If you walk into a deep pool until water touches your chin and look down you wil
"LAS VEGAS — Deep beneath Lake Mead, a 23-foot-tall tunnel-boring machine grinds through stubborn bedrock in a billion-dollar effort to make sure water continues flowing to this thirsty resort city.
For six years, the Southern Nevada Water Authority has been building an intake straw below the reservoir's two existing pipes. Due for completion in fall 2015, critics say it may not provide a long-term solution.
An ongoing drought and the Colorado River's stunted flow have shrunk Lake Mead to its lowest level in generations. The reservoir, which supplies 90% of Las Vegas' water, is ebbing as though a plug had been pulled from a bathtub drain. By mid-April, Lake Mead's water level measured just 48 feet above the system's topmost intake straw.
Future droughts and a warming climate change could spell trouble for the city's 2 million residents — and its 40 million annual visitors. Those people "better hope nothing goes wrong with the last intake," said water authority spokesman J.C. Davis."
Un éléphant de Sumatra a été retrouvé la tête mutilée et sans défenses dans l'ouest de l'Indonésie. La carcasse du pachyderme mâle, âgé de 20 ans environ, a été découverte, lundi, dans une forêt de la province d'Aceh, a déclaré Genman Suhefti Hasibuan, chef de l'agence locale de protection, qui a ajouté qu'une autopsie a permis d'établir que l'éléphant avait été abattu il y a un mois.
Sitting on a bench in the April sunshine, Al Cree is listing the birds he has spotted recently. "There's a kingfisher that flies past now and again," he says. "We have herons and cormorants regularly around here." He points to the river, where he lives on a houseboat. "Reed beds have been put in to clean water and attract wildlife," he explains. "When we first got here, the site was desolate, there was no green and hardly anyone came here. Lately more wildlife is coming into the area, and people can see it." Al is one of an army of volunteers who have regenerated Cody Dock in east London. Unlike the traditional bucolic setting, it stands under the gaze of the sky scrapers of Canary Wharf, accessed through a grey industrial estate on the outskirts of Canning Town.
Margie Peixoto was driving her pickup across her farm in the Brazilian state of Mato Grosso do Sul one February afternoon when she spotted some broken corn stalks and a trio of white-lipped peccaries (Tayassu pecari) ambling along the red-clay road as if they owned it. The moment these wild pig relatives spotted the truck, they snorted, snarled and disappeared into the head-high crop, where dozens more likely hid.
“Every year the group gets bigger and bigger, and every year the damage to the crop is greater,” said Peixoto, a fit middle-aged woman from Zimbabwe, who met her Brazilian husband while traveling in Africa, and immigrated here to farm more than 30 years ago.
Have you ever considered a chicken? Not as a nugget, kebab or omelet, but as a creature that has needs, feels pain and suffers.
The Commodity Bird
Chicken and eggs have been commodified by our desire for cheap plentiful meat and eggs; indeed, the word "chicken" has become the name of a product rather than that of an animal. More than 50 billion chickens are raised for meat and eggs worldwide annually, with about 10 billion of them in North America. In fact, chickens represent the overwhelming majority of agricultural animals in North America.
Nearly all North American chickens are raised and slaughtered in industrial operations. Despite the slick marketing, they do not live in bucolic bliss, roaming sunny meadows, dust-bathing and roosting in rustic sheds. Most chickens raised for meat, known as broilers, are engineered to grow rapidly in crowded barns with tens of thousands of other birds. The vast majority of hens producing our eggs spend their lives crammed, with several other birds, into small "battery" cages. The factory chicken's life is far removed from bucolic bliss.
Offshore and onshore, oil and gas operations and transportation appear no safer than before Five years after the BP Deepwater Horizon blowout in the Gulf of Mexico sparked national outrage, oil spills remain a routine occurrence across the United States. Yet many receive little — if any — national attention. The enormity and unprecedented scale of the BP disaster demanded a federal emergency response and captured daily headlines for months. But oil spills and pipeline ruptures occur daily – as they have nearly every day since the Deepwater Horizon exploded on April 20, 2010. While many are relatively small in comparison, they still pose threats to public safety, health, and the environment.
Reputation: Wolves have two public images. They inspire feelings of fear for their mad-eyed drooling, biting of children, and killing of livestock. But they also draw admiration for their strong, family-centric society, and as flagships of wild nature. Reality: These extreme views of wolves are deeply held, but are rooted in history rather than modern-day reality. In the highly modified landscapes of Europe and North America, it is time to rethink the meaning of wolf.
A group of Mexican engineers from the Jhostoblak Corporate created technology to recover and purify seawater or wastewater from households, hotels, hospitals, commercial and industrial facilities, regardless of the content of pollutants and microorganisms in just 2.5 minutes.
White mineral deposits circling Lake Mead behind Hoover Dam have emerged as water levels have fallen. The bathtub ring can be seen for miles. The 120-foot-high band of rock, bleached nearly white by mineral-rich water, circles the shoreline of Lake Mead. Water levels have dropped by almost 100 feet in the past decade, and the ring has emerged as a stark reminder of the drought enveloping the American Southwest. It also represents a looming crisis for the largest drinking-water reservoir in the U.S., one that has prompted the most ambitious water-construction project in recent history. Right now, 600 feet beneath the lake’s glassy blue surface, a massive custom-built tunnel-boring machine—almost as long as two football fields and heavier than four 747s—is plowing inch by tedious inch through wet, fractured bedrock. Spanning nearly 24 feet in diameter, its rock-gnawing face is alive with the movement of 44 disc cutters and 23 knives. The Big Gulp–style tunnel it is boring will eventually intersect with a concrete-and-steel riser installed in the bottom of the lake, like a drain. Two intake pipes already carry water from Lake Mead to Las Vegas, about 25 miles to the west. Known as the Third Straw, Intake No. 3 will reach 200 feet deeper into the lake—and keep water flowing for as long as there’s water to pump. Lake Mead is more than half empty. If the water drops another 50 feet, the first intake pipe will start sucking air.
However, Las Vegas still uses 219 gallons of water per person per day, one of the highest figures in the US. In San Francisco the figure is just 49 gallons. Most of that water is used to sprinkle golf courses, parks and lawns so the water authority has declared war on grass, paying homeowners to remove it from their gardens at the rate of $1.50 per square foot.
Campaigners in the Netherlands are taking the government to court for allegedly failing to protect its citizens from climate change. The class action lawsuit, involving almost 900 citizens, aims to force the government to cut emissions faster. The first hearing opened in the Hague on Tuesday. It is said to be the first time in Europe that citizens have tried to hold a state responsible for alleged inaction on climate change.
FABENS, Tex. — On maps, the mighty Rio Grande meanders 1,900 miles, from southern Colorado’s San Juan Mountains to the Gulf of Mexico. But on the ground, farms and cities drink all but a trickle before it reaches the canal that irrigates Bobby Skov’s farm outside El Paso, hundreds of miles from the gulf.
Now, shriveled by the historic drought that has consumed California and most of the Southwest, that trickle has become a moist breath.
