Pristine is relative to what type of ecosystem is in place at the time. The Sahara desert used to be a high rainfall area with jungle and as the rainfall dropped it became a desert. Does one now say that if it starts to come back we must start shoveling sand on to get back to the current pristine desert?
There are large tracts of the world that are experiencing die back of grasslands and desertifying.
Is it possible to rehabilitate our land?
In the forest environment, it is simple. Don’t burn it. Don’t cut it down and the forest will look after itself if left alone with increasing complexity and fertility The grasslands depended on large herds originally and long periods of recovery till the herds came back. Now we have too many animals stuck in one place. Everywhere where the animals aren’t is recovering. We have disturbed the natural migration routes of animals and our fencing has disturbed the natural situation… The pocketed game parks interspersed with farmlands. If we do nothing further what will happen? We need to stop being soil conservationists only we need to build soil. If you are losing soil, you are on a high road to ecological bankruptcy!
