You could argue that instead of using that land for grazing, it should be allowed to go wild again, helping to improve the nature. It is still usable by other species than humans and cattle. This would likely change the landscape and make the countryside look different. So there is a question about whether you want to change back to the 'original natural' landscape, or keep the cow managed 'agricultural-natural' landscape. There is a a similar discussion happening in the UK about re-wilding some moorland, should it be kept in it's current tree-less state, for grouse shooting and not particularly economical sheep grazing, or be reverted to a 'pre-human' state of forest. Only it has been the moorland for hundreds and hundreds of years, and it would actually take some intervention in some places to change to a forest due to the grazing by deer and lack of predators (due to humans killing them all). Personally I think there is room for both keeping some, and letting/helping some go wild.
