Flashback GMO Seeds: 'Multinational Corporations Gaining Total Control Over Farming'

Image
Food security campaigners are now more concerned than ever that farmers are turning dependent on large multinational corporations (MNCs) for seeds, fertilizers, pesticides and other inputs while also becoming more vulnerable to pressures to produce genetically engineered crops.

Gathered here over the weekend, for the Pesticide Action Network (PAN)'s 25th anniversary, many expressed concern over the predatory nature of corporate agriculture and its attempts to corner the entire chain of food production from seeds to sales of food products.

PAN is a network of over 600 participating non-governmental organisations, institutions and individuals in over 90 countries working to replace the use of hazardous pesticides with ecologically sound and socially just alternatives.

ANI Detecting clear trend in water vapor would take 50 years, say scientists

A new study by scientists has determined that it would take about 50 years of observations to detect a clear trend in upper tropospheric water vapor.

Water vapor in the upper troposphere contributes to the greenhouse effect, and scientists predict that humidity will increase in the future along with rising levels of atmospheric carbon dioxide.

However, there is currently no observing program that could detect the predicted trends.

Fossilised skull of 'sea monster' pliosaur found on Dorset coast

Ferocious prehistoric predator's skull is 2.4 metres and could belong to creature measuring up to 16 metres in length

The fossilised skull of a "sea monster", which may be the largest of its type ever found, has been unearthed on the Dorset coast.

The skull from the ferocious prehistoric predator the pliosaur is 2.4 metres long and could belong to a creature measuring up to 16 metres in length from tip to tail and weighing up to 12 tonnes.

Pliosaurs were a form of plesiosaur, a group of giant aquatic reptiles that terrorised the ocean 150m years ago, around the same time that dinosaurs roamed the Earth.

They had short necks and huge, crocodile-like heads that contained immensely powerful jaws and a set of huge, razor-sharp teeth.

Rainforest treaty 'fatally flawed'

Climate summit loophole lets palm oil producers cull vital wilderness

A vital safeguard to protect the world's rainforests from being cut down has been dropped from a global deforestation treaty due to be signed at the climate summit in Copenhagen in December.

Under proposals due to be ratified at the summit, countries which cut down rainforests and convert them to plantations of trees such as oil palms would still be able to classify the result as forest and could receive millions of dollars meant for preserving them. An earlier version of the text ruled out such a conversion but has been deleted, and the EU delegation - headed by Britain - has blocked its reinsertion.

Environmentalists say plantations are in no way a substitute for the lost natural forest in terms of wildlife, water production or, crucially, as a store of the carbon dioxide which is emitted into the atmosphere when forests are destroyed and intensifies climate change.

Pennsylvania: 3 More Earthquakes Rock York County

Three more earthquakes were reported in the Dillsburg, York County, area over the weekend.

Earthquake experts said that they all happened within a six-minute period at about 7:20 a.m. Sunday.

The first tremor was a magnitude 2.8, the second was a 1.8 and the third was a 2.6.

Some residents said that the quakes shook pictures on their walls.

"This time they are precipitated by a lot of rumbling and rolling we are hearing. So, we knew another was coming and in fact it did," said resident Candace LaGaza.

There have been more than 600 earthquakes in the area in the past year.

US: Out of control blaze in Santa Cruz Mountains

A fire driven by strong winds burned through 600 acres of the Santa Cruz Mountains this morning, burning two buildings, threatening 85 others and forcing evacuations.

Roughly 80 to 100 people were told to leave their homes in the area of Maymens Flat Road, Highland Way and Ormsby Cutoff. No injuries had been reported by mid-day, but two outbuildings and one trailer had been destroyed.

First reported around 3 a.m., the so-called Loma Fire started near Maymens Flat Road, close to the area that burned in the Summit Fire of 2008.

By late this morning, 937 firefighters were attacking the blaze, using 100 fire engines, eight air tankers and five helicopters, among other resources. But the fire remained completely uncontained.

The Summit Fire, which started in May 2008, burned more than 4,000 acres, injured 12 people and destroyed 132 homes and outbuildings, state fire officials said.

6.2 earthquake strikes Afghanistan and Pakistan

A strong earthquake centered in the towering Hindu Kush mountains shook a wide area of eastern Afghanistan and Pakistan early Friday, swaying buildings in the Afghan and Pakistani capitals.

There were no initial reports of damage or casualties from the quake, which struck about 12:21 a.m. Afghan time (1951 GMT, 3:51 p.m. EDT Thursday).

However, the temblor was centered in a remote mountain area where communications are poor and reports of casualties take time to reach the capital.

The earthquake had a preliminary magnitude of 6.2 and was centered in the mountains about 167 miles (268 kilometers) northeast of Kabul and 140 miles (230 kilometers) west of Mingaora, Pakistan, according to the U.S. Geological Survey.

Buildings shook in the Pakistani cities of Peshawar and the capital Islamabad, and the quake was felt as far east as Lahore near the Indian border, Pakistani television stations reported.

The Afghan Interior Ministry said it had no immediate reports of deaths or damage.

'Gatorade for frogs' could stymie fungal killer

The fungus now decimating frog populations around the world does its damage by impairing the animals' ability to absorb electrolytes through their skin. This discovery may eventually lead to treatments that make the disease less lethal.

Biologists now generally agree that the fungal disease known as chytridiomycosis is responsible for the worldwide die-off of frogs that has caused a conservation crisis in recent years. However, the fungus affects only the outer layers of the skin, leaving few clues to why it is so lethal.

But now Jamie Voyles of James Cook University in Townsville, Australia, and colleagues have an answer. In diseased frogs, the skin's ability to take up sodium and potassium ions from the water decreases by more than 50 per cent, they found. As a result, the concentration of these two ions in the frogs' blood fell by 20 and 50 per cent, respectively. This ion loss - similar to the hyponatraemia that a human athlete might experience from drinking too much water too fast - eventually leads to cardiac arrest and death.

California's coastal waters a dump for fishing gear

For the first time, scientists have used a submersible to investigate the debris piling up in deep-water canyons off the coast of California. To their surprise, they found that recreational fishing gear accounted for 93 per cent of the underwater trash.

"Sometimes we had to change the path of the submersible to avoid becoming entangled with recreational fishing lines and nets," says Diana Watters of the US National Oceanic and Atmospheric Administration's Fisheries Service in Santa Cruz, California.

"This is a really surprising result," says Anthony Jensen, who studies fisheries and artificial reefs at the National Oceanographic Centre in Southampton, UK, and was not involved in the survey. "Who would have thought that recreational fishers would account for more rubbish in a deep-sea ecosystem than the commercial fishing industry?"

Trash density

Watters believes that previous attempts to quantify underwater garbage by trawling with nets have underestimated the true scale of the problem because that method doesn't pick up all of what's down there and so cannot provide good information about the density of the debris. Nor can nets be dragged over rocky sea floors as they can snag on pinnacles.
