Seems to me the more "civilised" we become, the less we appreciate the wild spaces around us; and in consequence, the less connected and empathic we are with the living Earth and her remarkable diversity and wonder.
Locked in our urban caves - as so much of mankind now is - our gaze falls upon other people's caverns and we see only the wildness of humanity, not of nature; so are alienated from it. And when we do look further, it tends to be by virtual means, not actual.
We watch one of David Attenborough's marvellous documentaries, or a travel programme on some near-virginal island or ancient forest habitat, and imagine we are experiencing those realities - when we're merely peering in from the comfort of our La-Z-Boys.
Because seeing and experiencing are two very different things, fundamentally we're no longer touched as deeply as we should be by the widespread ecologic destruction happening all around us - somewhere just over the horizon.
The "Back to Nature" movement of the 1960s and 70s was a reaction to this: a visceral desire to directly re-connect to the "great outdoors" that feeds and sustains us. And though contemptuously belittled as a hippie dream, that movement gave rise to the reintroduction of organic farming practices that today produce premium foodstuffs throughout the Western world.
