The prediction that glaciers will be gone from Glacier National Park has been moved up by 10 years to 2020, the same year it's predicted the Arctic Sea will be ice-free in the summer.

Glaciers are almost gone from Glacier National Park.

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

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.

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

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