Flying - When I'm asked that question about finding their own balance, I simply respond I too would like nothin more than that. All you have to do is remove all people, concrete buildings, roads and lipecidatory svestock, re introduce predatory species and leave the country as if we have never been here!!
As thats not going to happen and we have meddled so much so far then we really have to continue with the role of top of the food chain!
Theres not really much of an arguement to have after that!
