Why promoting walking conserves human habitat and makes ecological sense

I'm a dedicated fitness walker; have been for four-plus decades. I was attracted to this article by the headline above (which I have repeated above). It's not just human habitat that's conserved, though. It's the habitat that's critical to the lives of our fellow brethren of Earth (the only planet we have). Sure, it's easier to get inside a car and isolate one's self from the world at large, but that's not what life is about. Walking burns calories, not a fossil fuel. Walking does not pollute the air; motoring about in an automobile does.

Is a 'view through the windshield' all that's left now? What about walking?

I've been walking -- for fitness and life -- all winter. Went for a five-miler yesterday, and got snowed on heavily from the midpoint on back to home. I'm a sucker for any article in most any mainstream media outlet having to do with walking. And that's walking for transportation, walking to see what America now looks like, and walking for fitness and health. Read this piece from the NY Times. Doing so made me think of the hundreds of times I wait and wait for a pedestrian "go" light to shine green.
