- University of Calgary's Aidan Hollis advocates user fees on non-human antibiotics use

Citing an overabundance in the use of antibiotics by the agriculture and aquaculture industries that poses a threat to public health, economics professor Aidan Hollis has proposed a solution in the form of user fees on the non-human use of antibiotics.

In a newly released paper published in the New England Journal of Medicine, Hollis and co-author Ziana Ahmed state that in the United States 80 per cent of the antibiotics in the country are consumed in agriculture and aquaculture for the purpose of increasing food production.

This flood of antibiotics released into the environment – sprayed on fruit trees and fed to the likes of livestock, poultry and salmon, among other uses – has led bacteria to evolve, Hollis writes. Mounting evidence cited in the journal shows resistant pathogens are emerging in the wake of this veritable flood of antibiotics – resulting in an increase in bacteria that is immune to available treatments.

If the problem is left unchecked, this will create a health crisis on a global scale, Hollis says.

Hollis suggest that the predicament could be greatly alleviated by imposing a user fee on the non-human uses of antibiotics, similar to the way in which logging companies pay stumpage fees and oil companies pay royalties.

"Modern medicine relies on antibiotics to kill off bacterial infections," explains Hollis. "This is incredibly important. Without effective antibiotics, any surgery – even minor ones – will become extremely risky. Cancer therapies, similarly, are dependent on the availability of effective antimicrobials. Ordinary infections will kill otherwise healthy people."

Bacteria that can effectively resist antibiotics will thrive, Hollis adds, reproducing rapidly and spreading in various ways.

"It's not just the food we eat," he says. "Bacteria is spread in the environment; it might wind up on a doorknob. You walk away with the bacteria on you and you share it with the next person you come into contact with. If you become infected with resistant bacteria, antibiotics won't provide any relief."

While the vast majority of antibiotic use has gone towards increasing productivity in agriculture, Hollis asserts that most of these applications are of "low value."

"It's about increasing the efficiency of food so you can reduce the amount of grain you feed the cattle," says Hollis. "It's about giving antibiotics to baby chicks because it reduces the likelihood that they're going to get sick when you cram them together in unsanitary conditions.

"These methods are obviously profitable to the farmers, but that doesn't mean it's generating a huge benefit. In fact, the profitability is usually quite marginal.

"The real value of antibiotics is saving people from dying. Everything else is trivial."

While banning the use of antibiotics in food production is challenging, establishing a user fee makes good sense, according to Hollis.

Such a practice would deter the low-value use of antibiotics, with higher costs encouraging farmers to improve their animal management methods and to adopt better substitutes for the drugs, such as vaccinations.

Hollis also suggests that an international treaty could ideally be imposed. "Resistant bacteria do not respect national borders," he says. He adds that such a treaty might have a fair chance of attaining international compliance, as governments tend to be motivated by revenue collection.

Hollis notes that in the U.S., a move has been made to control the non-human use of antibiotics, with the FDA recently seeking voluntary limits on the use of antibiotics for animal growth promotion on farms.

He asks: "Is the Canadian government going to take any action to control the use of antibiotics for food production purposes? Health Canada is trying to monitor the use of antibiotics, but has virtually no control over use."

Although earthquakes have largely ceased for the moment, the island experiences ongoing rapid inflation and harmonic tremor, both signs that an eruption could be imminent. The inflation in the SE part near El Pinar and La Restinga has reached almost 10 cm in just a few days by now. Instead of new earthquakes, harmonic tremor (steady low-frequency ground vibration) has appeared 2 days ago and since then been gradually increasing. Both observations, as well as some single long-period earthquakes in the past days, are indicators of magma moving into the system and pressurizing it. This means that the scenario of a new eruption has become more and more likely. It is impossible to say whether and when a new eruption will occur, but it could happen quickly any time. It would probably begin with a series of stronger earthquakes to open up a conduit. Based on the inflation and earthquake patterns, the most likely area would be near the 2011 vent near La Restinga, perhaps even on land. In this case, La Restinga would be the village most at risk. The previously detected very high Radon gas emission values also suggest the presence of new magma and pose a health risk particularly in closed low-lying rooms of buildings especially in southern El Hierro.

The level of the Dead Sea has continued to drop. Despite heavy rains in the past three monts and lower than normal temperatures, the Dead Sea has fallen another 3 cm. Water level has reached a level of 427.82 meters (1,403 feet) below sea level.

Ten years ago, the Dead Sea was 11 meters higher than today 

According to Hydrological Services, the additional drop in the Dead Sea's water level brought the basin to 0.93 meters (3 feet) below its level one year agodata indicated. The Dead Sea's water level lost 8 centimeters (3.1 inches) in November and 14 centimeters (5.5 inches) in October. Ten years ago, the Dead Sea basin's water level was 416.77 meters (1,367 feet) below sea level, 11.05 meters (36 feet) higher than the current level.

The average annual reduction in water level for the Dead Sea is now 1.105 meters (3.6 feet).

Two days of heavy rains set off floods and landslides in the southeastern Philippines, leaving at least 20 people dead, 13 missing and thousands displaced, officials said Monday. Most of the dead and missing came from floods and landslides that hit Compostella Valley and Davao Oriental provinces, said Maj. Reynaldo Balido, spokesman for the disaster-response agency. A landslide Monday damaged five houses in Cagdianao municipality in Dinagat Island, off the northeastern coast of the main southern island of Mindanao, killing six residents including two boys aged 2 and 14, said police officer Elbert Ompoc. Another man drowned in Agusan del Sur province’s Prosperidad Township, on Mindanao, and seven others were missing, according to the civil defense regional bureau. The flooding, triggered by rains from a low pressure area, has affected 132,000 people from 10 provinces. Liza Mazo, a regional disaster-response official, said some 10,000 people fled to safer grounds in four provinces and an island. The same area was hit by a typhoon in December 2012, leaving nearly 2,000 people dead and missing and causing massive destruction. Government weather forecaster Gener Quitlong said rains may persist until Tuesday or Wednesday over central provinces, including those hit by Typhoon Haiyan, which killed more than 6,100 people and left nearly 1,800 others missing on Nov. 8.

Hundreds of witnesses reported seeing a large fireball brighter than the nearly full moon over New England at 5:20 pm EST on Sunday, January 12, 2014. Most reports came from Connecticut, but the fireball was also seen from Massachusetts, Rhode Island, New York, New Jersey, Pennsylvania, New Hampshire, and Maine. Based on the reports, the estimated trajectory of the fireball is from southwest Vermont heading north and terminating over Rutland County.

If you saw the fireball, you can file a report with the American Meteor Society.

 

There is a lot of suspicion that the above photo may be an airplane instead of a meteor.Check out this link for similar photos of contrails near sunset.
