Law bans Internet images that cause 'emotional distress' - Weird News - Canoe.ca
There goes the Internet. A new Tennessee law makes it a crime to post an image online that might "frighten, intimidate or cause emotional distress" to someone. As reported by the technology website Ars Technica, the state already has a law against making phone calls, sending e-mails or otherwise communicating with someone in a way that would cause emotional distress. This latest ban, signed by Gov. Bill Haslam last week, is an update to that law. The difference is that offenders may be prosecuted even if it's not the intended recipient who is "distressed." Anyone who sees the image - which means anyone on the Internet - could claim it upset them. Prosecution can lead to almost a year in jail or up to $2,500 in fines. The law even includes postings on social networking sites, giving law enforcement access to those drunken Facebook photos and tweeted pictures of your lunch if they can demonstrate that the content is "relevant and material to an ongoing criminal investigation." Privacy experts, including UCLA law professor Eugene Volokh, say the law is unconstitutional. |

Can’t See The Forest For The Trees
BLOGS NOSEY PARKER
Can’t See The Forest For The Trees
Although the vast majority of Canadians live in urban environments, we tend to define ourselves as a nation through the rugged, wild, natural character of our country.
If asked to describe Canada, most of us would reference water in some form, mountains or rock (depending on where you live), rolling prairies (again depending on where you live), ice and snow in winter, sweltering heat and mosquitos in summer.
But above all else, I think, we define our country as a land of forests — vast, uncountable swathes of trees spreading endlessly north to the Arctic and west (or east, depending on your coast) to the grasslands of southern Saskatchewan and Alberta.
Forests so endless that we could have half a dozen fires, each bigger than Prince Edward Island, raging in Northwestern Ontario this summer and barely be aware of their existence down here on the muggy shores of the Great Lakes.
We take nature’s bounty for granted and look with a certain smug condescension on other nations of the world who do not have such vast, limitless resources or are in the process of squandering what they do have.
I was stunned to find out — and I am assuming you will be too — that this view of ourselves and our position in the natural world is a load of crap.
Really. I know it’s hard to believe, but let me explain.
Just to put your head in the right space, consider these three points:
1. The United States has far, far more forested land than Canada — more than 300 million hectares compared to just over 200 million hectares for poor, barren Canada.
(I visually judge large areas in units of football fields; I cannot conjure up a mental picture of either an acre or hectare, so we’ll stick with the metric hectare since those are the figures I have. A CFL field, by the way, is about two acres and it takes about 2.47 acres to make a hectare so Canada has about a quarter billion CFL football fields worth of forest by my count.)
2. When I think of China, I think of the world’s most populous country — more than 1.3 BILLION people — and one of the world’s oldest societies. A land, in other words, that has been intensively cultivated for eons, a land of rice paddies, not forests. Wrong again. China is smaller in total area than Canada but today has almost exactly the same amount of forested land as Canada — but with an extra 1,265,000,000 mouths to feed.
I’ve been to China, I travelled through its countryside, I’ve hiked in its forests … but I always subconsciously felt there was a city of teeming millions or a sprawling industrial complex just beyond the treeline. Wrong again.
One of these photos is from Canada and one is from China. Can you tell which is which?
Answer: Top photo is from Inner Mongolia, bottom photo is from British Columbia
3. Canada’s forest change is basically neutral — new forests grow or are cultivated at approximately the same rate as old forests are cut down or destroyed by fire or pestilence — but both China and the United States are growing more and more forests every year. Over the past decade, U.S. forested land has increased by about a third of one percent each year. Not bad, but nothing compared to China’s staggering 3% a year forest growth rate.
(All this data comes from the wonderfully informative and reliable Economist magazine, which in turn is using global satellite analysis collected by Brazil’s Instituto Nacional de Pesquisas Espaciais — National Institute for Space Research — to track deforestation in the Amazon and keep tabs on the rest of the earth’s forests.)
So, despite our self image, Canada does not have as much forest wilderness as we believe in our guts we do and we don’t do as good a job as those nasty industrial carbon footprinters, the United States and China, in replenishing our forests.
Here’s a chart The Economist ran a few days ago showing the world’s top 10 countries with largest forest area and here’s a link to the online article accompanying the chart at www.economist.com.
As you can see, Mother Russia has by far the most forest on earth, at around 800 million hectares, followed by Brazil at more than 500 million hectares. (They’re both chewing through their forests at a fair clip, Brazil especially, but that’s a discussion for another time. The fact remains that Russia has four times the amount of forest that Canada does and Brazil’s forested area is about 2.5 times greater than Canada’s, both of which comparative circumstances surprised me. I would have said Russia’s forests were at most double the size of Canada’s and that Canada probably had more forest coverage than Brazil.)
Then there’s the U.S. at about 300 million hectares, Canada and China at just over 200 million hectares each, followed by the rest of the world.
(Again, I would also have said Canada has two or three times more forest than the U.S. I’m starting to get a case of wood envy.)
The next five have some interesting revelations.
For starters, I never would have believed that Australia and Sudan have some of the largest forests in the world. I think of them both as being basically arid desert countries.
And I thought India, like China, had too many people and too much history of human habitation to have much in the way of forests left. And, yes, I’m impressed that India has been increasing its forested land by about .3% a year over the past decade.
So I guess I’ve changed the way I look at Canada and the rest of the world. I don’t feel quite so smug about our endless, majestic wilderness.
It’s still there and still vast and still defines us to a large extent, but there are cautionary limits as well.
I think I’ll go out and hug a tree.
Then I’ll dip a toe in Canada’s vast, endless supply of pure, fresh water.
Hey, where did all the water go?

What to know about cellphones and cancer
What to know about cellphones and cancer
When the World Health Organization — the world's leading health authority — declares that cellphones may cause a rare but often deadly form of brain cancer, consumers take notice. Making sense of the declaration is much trickier.
Here's a primer on the new classification by the WHO's International Agency for Research on Cancer.
What is the new designation and how did the agency made it?
IARC's working group waded through the exposure data from cancer studies involving humans and experimental animals. The 31-member group, including two Canadian researchers, this week declared that radio-frequency electromagnetic fields from cellphones could be "possibly carcinogenic to humans" based on the increased risk forglioma, a malignant type of brain cancer, associated with wireless phone use.
What does that mean?
This category is used when there is limited evidence of carcinogenicity in humans and less than sufficient evidence in experimental animals. (Other categories in IARC's monographs include the more alarming "carcinogenic" and "probably carcinogenic." Less worrisome categories include "not classified as to its carcinogenicity" or "not carcinogenic.")
"It doesn't demonstrate or prove or absolutely condemn radio-frequency fields as causing cancer, but it's a first level of concern," says Jack Siemiatycki, an epidemiologist from the University of Montreal and a member of IARC's working group.
Daniel Krewski, the director of the McLaughlin Centre for Population Health Risk Assessment at the University of Ottawa, says: "This is quite a significant determination. 'Possibly carcinogenic to humans' does not mean it's absolutely sure that that's the case, but enough evidence has accrued that we should be concerned and do additional work to clarify the extent of the risk if one actually exists." Krewski also contributed to IARC's massive cellphone study.
What else is classified as "possibly carcinogenic"?
There are 266 agents classified in this group. Two food products are on the list: coffee (urinary bladder) and pickled vegetables. Other items deemed "possibly carcinogenic" include certain dry-cleaning chemicals, pesticides like DDT, diesel fuel, engine exhaust, lead, nickel and vinyl acitate.
What is the science behind all this?
Multiple studies were considered, but epidemiological data from IARC's massive INTERPHONE study, led by a Canadian researcher and involving 13 countries including Canada, were thought particularly relevant. The largest study ever conducted on cellphone use and brain cancers found no overall increased risk of cancer. But it did report that the heaviest cellphone users had a 40 per cent higher risk of a particular cancer: glioma. The data were collected up to 2004 and the highest category of heavy users was defined at that time as spending an average of 30 minutes per day on a cellphone over a 10-year period. (Cellphone use these days, of course, can run much higher than 30 minutes a day.)
What does a 40 per cent increased risk of glioma mean? Krewski concedes that 40 per cent "sounds high," but noted that it applies only to long-term, heavy users of cellphones, not the entire population.
As well, glioma rates normally vary by age, gender, region and other factors but are generally in the range of three to five cases per 100,000 population. Assuming that two-thirds of the Canadian population uses a cellphone, and only 10 per cent are heavy users, the increase would be hard to quantify in the general population.
What are the limitations of the science?
The University of Southern California's Jonathan Samet, chairman of IARC's working group, says there are "acknowledged gaps and uncertainties" in the current research, including the INTERPHONE project. In addition to a low participation rate, he says the INTERPHONE studies relied on people's recollections of cellphone use over the years, which he calls "inherently imperfect."
So are the data still valid?
Tumours can take 10 to 30 years to develop after the initial exposure, but cellphones have only widely been used since the 1990s. And the INTERPHONE data, collected until 2004, preceded the recent explosion of cellphone use, when consumers began dropping land lines altogether in favour of cellphones.
"Of course, as use patterns continue to grow, we can anticipate an ever larger population that is exposed for longer and longer," says Samet.
What's next?
Everyone agrees more research is needed. After that, things are muddy.
Siemiatycki says the classification "calls for attention to be given to the problem," but he's less definitive about whether that means industry, health agencies and governments should take action at this stage.
"I'm not really competent to make that call. It's a public health issue at that point," he says.
What is Health Canada saying?
At this stage, it's not conceding any increased danger.
"Health Canada's advice to Canadians remains the same. As long as exposures respect the limits set in Health Canada's radio-frequency (RF) exposure guidelines, the department has no scientific reason to consider exposure to low-level radio-frequency fields, such as those from cellphones or Wi-Fi, dangerous to the public," it says.
What should Health Canada should be saying?
Siemiatycki says he'd like to hear a change in tone and see action on the file.
"I'm not sure what they would have said (before the classification), but I guess today they would have to say they're really doing it, that they're really looking into it. They should either stimulate additional research or they should look at preventive strategies that might not be disruptive to people or to society, or to give warnings, I'm not sure. But they would need to look at this possibly in a more serious way than they did" before IARC's announcement this week.
Should I stop using my cellphone?
IARC isn't going that far, but director Christopher Wild says that, "given the potential consequences for public health of this classification and findings," additional research on long-term, heavy-use of mobile phones is vital. And "pending the availability of such information, it is important to take pragmatic measures to reduce exposure." Wild suggests using texting and hands-free devices or ear pieces, rather than ditching the cellphone altogether.
Should I take steps to minimize my risk?
It's your call, says Siemiatycki.
"People can respond to this according to their personal levels of concern, how they react to these kinds of possible hazards in society. So many things that we do carry some risk, whether it's driving on highways or whatever, and we make decisions constantly about risks that we're willing to take or not willing to take. For the time being, for the individual user, anyone who is concerned about this — and it's not unreasonable to be concerned about this — can have options for reducing their exposure to radio-frequency fields from mobile phones. The easiest is to use hands-free devices," said
Krewski says this makes sense. "Well, I think at this point, once the International Agency of Cancer Research identifies an agent as possibly carcinogenic to human, I don't know if we want to wait for the final definitive science to accrue. I think we should be a little bit careful. "
