My understanding of Permaculture design is a three-dimensional food forest, with minimal energy expenditures. Since goats eat just about every single thing they come in contact with, that means they need to be kept separate from just about everything.
When I say "destroyed" - I mean, the goats have cleared off that land. My father is quite happy with what he sees - "pasture". It looks almost like it has been mowed, like a lawn. I think most people would look at it and see absolutely nothing wrong, in fact, they would look at it and consider it improved.
Whenever I see a mowed lawn, I see a monoculture desert.

1. Oyster farming in estuaries
This can be very sustainable. Near Jacksonville Florida are small hills of oyster shells left by the Timuquan people who lived there for thousands of years eating oysters until they made oyster shell middens which are the highest spots in the area. And you can look out into the water and see plenty of living oysters even to this day!
