SLFP Project Director Toby McLeod contributed advice and archival footage to this timely documentary on renewable energy development in Indian Country.

POWER PATHS offers a unique glimpse into the global energy crisis from the perspective of a culture pledged to protect the planet, historically exploited by corporate interests and neglected by public policy makers. As Anishinaabe activist Winona LaDuke says in the film, “We need to create a way of life where a community is not forced to cannibalize their mother in order to live.”

The film follows an intertribal coalition as they fight to transform their local economies by replacing coal mines and smog-belching power plants with renewable energy technologies. POWER PATHS follows the Just Transition Coalition in its attempts to balance Navajo and Hopi losses from the 2006 closure of the Mohave Generating Station and Peabody Energy’s Black Mesa mine by creating green jobs. This transition would honor their heritage, protect their sacred land, and provide electricity to their homes. At a time when the planet as a whole hungers for alternatives to fossil fuels, POWER PATHS offers proof that going green is not only possible—it’s the only choice we have.

In the Bay Area, POWER PATHS is scheduled to air at 10 p.m., Tuesday, Nov. 3. Check local listings for your PBS station, or visit the PBS website.


Mobile Use Is Linked To Brain Tumors

30 10 2009

CellPhoneChildHandLONG-term mobile phone users could face a higher risk of developing cancer in later life, according to a decade-long study.

The report, to be published later this year, has reportedly found that heavy mobile use is linked to brain tumours.

The survey of 12,800 people in 13 countries has been overseen by the World Health Organisation.

Preliminary results of the inquiry, which is looking at whether mobile phone exposure is linked to three types of brain tumour and a tumour of the salivary gland, have been sent to a scientific journal.

The findings are expected to put pressure on the Government – which has insisted that mobile phones are safe – to issue stronger warnings to users.


Study charts links between mobile phones, tumors

Study charts links between mobile phones, tumors
High-quality studies often show potential cancer link

Industry-funded studies most likely to show no link
By David Morgan

WASHINGTON, Oct 13 (Reuters) – Studies on whether mobile phones can cause cancer, especially brain tumors, vary widely in quality and there may be some bias in those showing the least risk, researchers reported on Tuesday.
So far it is difficult to demonstrate any link, although the best studies do suggest some association between mobile phone use and cancer, the team led by Dr. Seung-Kwon Myung of South Korea’s National Cancer Center found.
Myung and colleagues at Ewha Womans University and Seoul National University Hospital in Seoul and the University of California, Berkeley, examined 23 published studies of more than 37,000 people in what is called a meta-analysis.

They found results often depended on who conducted the study and how well they controlled for bias and other errors.

“We found a large discrepancy in the association between mobile phone use and tumor risk by research group, which is confounded with the methodological quality of the research,” they wrote in the Journal of Clinical Oncology.

The use of mobile and cordless phones has exploded in the past 10 years to an estimated 4.6 billion subscribers worldwide, according to the U.N. International Telecommunication Union.
Research has failed to establish any clear link between use of the devices and several kinds of cancer.

The latest study, supported in part by the U.S. Centers for Disease Control and Prevention, examined cases involving brain tumors and others including tumors of the facial nerves, salivary glands and testicles as well as non-Hodgkin’s lymphomas.

It found no significant association between the risk of tumors and overall use of mobile phones, including cellular and cordless phones.


Myung’s team said eight studies that employed “high quality” methods to blind participants against bias found a mild increased risk of tumors among people who used mobile phones compared with those who never or rarely did.

An increased risk of benign, not malignant, tumors was also found among people who used the phones for a decade or longer.

The “high quality” studies were funded by the Swedish Work Environment Fund, the Orebro Cancer Fund and the Orebro University Hospital Cancer Fund, Myung’s team said.

By contrast, studies that used “low quality” methods to weed out bias found mobile users were at lower risk for tumors than people who rarely used the devices.

Myung’s team suggested those results could be marred by random errors and bias because of the quality of the methods.

Funding for some of the lower-quality studies included two industry groups, the Mobile Manufacturers Forum and the Global System for Mobile Communication Association, the researchers said.

Overall, the studies examined were not broad enough to shed light on whether mobile phone use could cause tumors. Myung’s team said larger studies of a type called cohort studies are needed to answer that question.

Such studies follow a group of people who share a characteristic, in this case cellphone use, and compare them with other groups over time.

The only cohort study published to date showed no association between mobile phone use and tumors. But the study, conducted in Denmark, relied on telephone subscriptions and did not evaluate actual exposure to mobile phones. (Editing by Maggie Fox and John O’Callaghan)
