The Fisheries Turnoff

I was watching David Suzuki’s “One Ocean” on CBC Television last night, and I was again struck by one fisheries biologist’s arrogance–his choice of words, his tone of voice, his meaning. When he spoke of forcing a smile onto his face at public meetings and inquiries, he was not only insulting his audience, he was admitting insincerity. And why would anyone want to cooperate with an arrogant, insincere fisheries biologist?

Fisheries biology is an interesting field of study, but it often attracts (and subsequently recruits) autocratic individuals who as teenagers and young adults failed to muster enough smarts to succeed at jobs requiring higher levels of creativity, originality, and diplomacy. read more

Toronto Waterfront, Leslie Spit, Cherry Beach

It was over 90 degrees in July, and with the humidity, that temperature had the effect of 104 degrees, but starting at 2 PM, I hiked from Yonge and St. Clair to the waterfront and then on to Cherry Beach and the Leslie Spit in Toronto, Ontario, Canada. Then I hiked back to where I started on Yonge Street and St. Clair Avenue. (Yonge is the longest municipal street in Canada.) Click on the photos:

Hiking Photos from Bruce Trail and Grand Canyon

Here are a few of the photos I took on my hikes in Arizona and Ontario. I use a small Japanese-made Minolta.

I took the Arizona shot on the Tanner Trail in the Grand Canyon and the Ontario shots on the Beaver Valley and Sydenham sections of the Bruce Trail (Maps 28 and 29 of the Bruce Trail Reference: Edition 25), about 10 km south of Meaford, Ontario. (Did you know that John Muir once lived in Meaford?). Compared to Arizona, the Bruce Trail does not present large elevation changes, but its moss-covered rocks and boulders are extremely slippery. read more

Flat Feet and Arch Supports

Maybe you visited your doctor after taking up running, and the doctor told you that your feet hurt because your arches fell. In other words, you have flat feet. Well the chances are that it’s your shoes, not your flat arches, that are causing the pain. The arch supports hurt your feet: You do not want humongous arch supports. You want shoes that are built with very mild (low) arch supports.

Both New Balance and Vasque make athletic shoes that fit flat feet and wide feet. Vasque even says that their Perpetuum last is “comfortable for people with flatter feet.” read more

They Say Vegetables Don’t Stop Cancer. I Don’t Believe It.

This week the media told us all that a new study shows that eating lots of vegetables does not “significantly” lower cancer risk. (The study indicates that vegetables might provide a very small reduction in cancer risk, but that statistic may have resulted from reporting error and bias — see Eating Vegetables Doesn’t Stop Cancer: http://well.blogs.nytimes.com/2010/04/08/eating-vegetables-doesnt-stop-cancer/.)

The cancer researchers had 142,605 men and 335,873 women report on their eating habits and lifestyles during 1992 to 2000. They then assessed the association between cancer risk and diets high in fruits and vegetables. read more

Dangerous Household Ozone Generators

Last month I looked up information about in-home ozone generators. A friend of mine was thinking of buying a house in Arizona (she bought it), and the sellers were using indoor ozone generators. The ozone gave my friend a severe headache and caused her blood pressure to rise to dangerous levels. (She takes blood-pressure medication and had to increase the dosage after inspecting the house.)

I rushed to my computer and found quite a few useful websites, and, yes, ozone causes headaches, high blood pressure, sore throats and coughs (see Effects of Ozone Pollution on Seniors and Ozone Generators May Be Dangerous to Your Health). Ozone irritates the lungs, exacerbates lung disease, accelerates aging, and damages home electronics and wiring. In combination with air fresheners or household disinfectants, ozone will produce formaldehyde, a chemical that can cause cancer (see Study Warns of Cleaning Product Risks). The California Department of Health Services began warning consumers about indoor ozone generators back in the 1990s. And Health Canada says, “If you have an ozone generator in your home, stop using it.” read more

The Grand Canyon State: Arizona Set to Close and Sell State Parks?

The world flies in and takes a long look at Arizona, the Grand Canyon State (see our Photo Gallery, our Arizona Gallery, and our Grand Canyon Trails Page). And soon after arriving in Phoenix, they fall in love with all the other gems Arizona has to offer: preserved yet accessible desert wilderness areas and wildlife refuges, such as the Lost Dutchman State Park in Apache Junction.

But now Arizona’s lawmakers are preparing to vote on budget cuts that could shut down the entire state parks system by July 1. And that vote in January 2010 might result in the sale of state parks to the highest bidders. That’s right: I’m hearing that once an Arizona state park is closed, it must be sold: Land speculators and developers will mutilate our public gems, our community wilderness. They will restrict access, and Lost Dutchman State Park will become a gated community or a private suburb, with lot and house prices starting at $700,000 or more. read more

BPA-free Biodegradable Plastic Bottles

We hear about how plastic bottles are filling our landfills and oceans, but bottled water manufacturers and consumers can solve this problem. We do have biodegradable choices, and biodegradable plastic may cost us a little more in the short term, but I’m sure the costs will fall in the future, as our health and our planet’s health improve.

See www.biogreenbottles.com and BioGreen Biodegradable BPA-Free Sport Bottle with Wide Mouth DuoFlow Lid (26-Ounce). These bottles are BPA, DEHA and DEHP Free, and they are made in the USA. read more
