Wilderness, like the national park system, was an American idea.

Glaciers are almost gone from Glacier National Park.

I grew up on the edge of a national park in Canada - timberwolves, creeks, snow drifts.

What people ought to do is find out what a national park is to begin with.

I haven't been to Tasmania. I haven't been to the South Pole, and I haven't been to the North Pole. I want to see the polar bear migration before there are no polar bears. I want to see Glacier National Park before the glacier melts.

I got involved in Gateway National Park and just became fascinated with gardens.
