I talk to children in schools all over the world, and I've found that both boys and girls are fascinated by how hunter-gatherers manage to survive entirely on what's around them in their environment: trees, rocks, animals and plants.

The most remote place I've been to was in Greenland. I remember setting out for a solo hike from a small cabin, itself several hours' boat ride from the nearest settlement.
I think true wilderness can still be found, but it's hard to reach and dangerous when you get there, which is probably why it still exists.
