Sorry, this is patently false. Permaculture isn't about "going back in time" its about re-jigging things so that you are not having to put in a tonne of nutrients only to take them out again/let them be blown away. For example in wide open pastures it can be as "simple" as planting trees for nuts/fruit/lumber widely spaced to cut down on wind. not only that but it cuts down on the need for water because. This makes up for the reduction in sunlight getting to the grass. aquaculture is about trade-offs. its about choosing overly high yield now, with ever increasing fertiliser/feed/water inputs (thus higher costs) or reduced yield in the setup phase for much more resilient/comparatively productive and cheaper yields in future.
