Researchers tell us one way to stay trim is to walk more often.

But that’s hard in some neighborhoods – maybe sidewalks are bad or there are no stores to walk to.

Shawn Allee found one researcher who thinks what really stops us … is actually in our heads.

Dr. Tanya Berry researches physical activity, and she surveyed people living in Edmonton, Canada.

She calculated how trim or fat they were, then she logged details about their neighborhoods, things like how many stores are nearby and how many cars pass through the area.
Berry says the thing that mattered most, and kept people from walking was a subjective feeling that there are too many cars on the street.

“There was too much traffic in their neighborhoods, it made it difficult to walk, so they chose to jump in their cars and contribute to the traffic problem.”

Berry says her research team will look at how buildings and streets can be designed to make pedestrians feel there’s less traffic than there actually is, and maybe feel more comfortable walking down the street.

Biggest Health Threat: Inactivity

lot simpler. Kyle Norris reports:

Many of us have engineered physical activity out of our lives. We sit in front of the computer, we sit and drive everywhere. We don’t move much.

That’s what Steven Blair says. Blair is a professor of Public Health at the University of South Carolina. And he says, more than anything else, America’s physical in-activity will cause this century’s biggest public health problems.

“You want to stay out of the nursing home, the best insurance you can take out is regular physical activity program – three ten minute walks five days week. I’m not talking about training for the Ironman triathlon or a marathon.”

He says we need to re-engineer physical activity back into our lives. And part of that includes making communities super walk-able and bike-able.

Seniors Find Niche in Environmental Work

Environmental work isn’t just for young professionals anymore.
Retired engineers, former biology teachers, and others with time on their hands are working on

environmental problems as volunteers. The Great Lakes Radio Consortium’s Jennifer Szweda Jordan

reports on how senior citizens are keeping environmentally active:


(Sound of bird)


75-year-old Ivan Pettit is officially retired from his job as an environmental regulator, but he

hasn’t stopped monitoring streams, promoting recycling, and solving a nagging safety issue in his

state.


(Sound of walking)


On a sunny day in Oil Creek State Park in northeast Pennsylvania, he drops a stone down a corroded

pipe.


“Okay, go.”


(Sound of rattling, splash)


Pettit is estimating the depth of this remnant of an old oil well. It’s one of thousands of

abandoned oil wells in this region. The wells date as far back as 1859. Pettit and a team of senior

volunteers regularly hunt for old wells. The seniors’ work improves water quality and safety for

hikers and hunters, and Pettit says it helps keeps him fit.


“It is work that I have always enjoyed doing as well as getting you outdoors and being able to

observe the things that’s going on around you, that is not a sedentary task whatsoever.”


Pettit belongs to the national Environmental Alliance for Senior Involvement. The group claims

members as young as fifty-five. Pennsylvania has the third highest number of residents older than

sixty among U.S. states. Its active Senior Environmental Corps is touted as a national model, and

has been honored by the United Nations Environmental Program.


But senior groups across the nation are working on environmental problems. In Cape Cod, they

monitor West Nile virus. Seniors clean hazardous waste sites in Indiana. Michigan volunteers

install solar water heaters on poor peoples’ homes.


It’s a fast growing program. In 1993, 26 older adults made up the Senior Environment Corps. A

decade later, over 100 thousand were involved in work across the country.


Ivan Pettit’s work looking for old oil wells is the kind of effort that makes a real difference.

Besides being a hazard for hikers and hunters, some of the old wells seep oil into the ground and

it gets into streams.


In less than two years, the seniors have found almost two hundred wells. Environmental Alliance for

Senior Involvement president Tom Benjamin compares that to two college interns who worked full-time

one summer, and found fewer than fifty.


“Most of these individuals that were volunteers know that community and know the area. They grew up

there, they hunted those woods, they know what a oil well looks like, so they have some instant

recognition.”


(Sound of forest)


Every other week, from spring to fall, the well hunters line up horizontally, twenty feet apart,

and comb a section of forest. Some well holes are several feet across and twenty feet deep. Others

have narrow openings, but drop as deep as a thousand feet. Evelyn Kolojejchick and her husband John

lead Ivan Pettit and other volunteers in seeking out the wells and marking coordinates.


“Ok, longitude is?”


“Seventy-Nine.”


For both Evelyn and John Kolojejchick, well-hunting and other environmental projects are an

extension of teaching high school science for thirty years. Evelyn once aimed to spark interest in

many young minds. Now she feels she’s working on a smaller scale, but hopes to remain effective.


“I belong to Audubon, used to belong to a lot of other environmental organizations and it just

seemed like you needed… you needed to do something that was going to make a difference. I never

had any money to donate to all of these causes and you just you know, you want to do something that

an individual can do.”


Recently, the seniors saw results of well-hunting. They found sensitive species in a stream that

had once been polluted. Several oil wells nearby had been sealed with cement to keep acid mine

drainage out of the water.


“The first year we tested it for aquatic life, there was almost nothing there. And yesterday when

we were there, we had better diversity in that stream than we have in some of our streams that we

test all along that we know don’t have those kinds of problems. So they have made a significant

difference on that stream by plugging those wells. It’s remarkable.”


And it’s the kind of reward that these senior citizen volunteers had hoped for: making a difference

in their part of the world.
