An 'international' perspective is fine and good when it comes to the Christian religion, and the mystical and literal fact of us all being God's children; but within that context patriotism - indeed regionalism, localism and parochialism - is the natural and healthy basic stance for any real environmentalist.
But the bought-and-sold and thoroughly-subverted modern Green political movement is relentlessly inter-nationalist - being far more fascinated by travellers' tales from exotic places than the doings of the actual neighbours; and being cravenly servile to the globalising agenda of the international super-rich cabal of billionaires and mega-celebrities whose exclusive meetings are (apparently) festivals of idealistic environmentalism...
The Greens' 'global agenda' (especially in relation to Climate Change) is a perfect excuse to impose centralised totalitarian systems of bureaucratic universal monitoring and micro-control - with obscene bribes and harsh punishments as the carrots and sticks.
(What place in these strategic plans for the bloody-minded independent farmer with his family living off 'three acres and a cow'?)
The same applies to their spirituality - which is usually some kind of eclectic sampling of remote Eastern religions; Hindu, Buddhist, Sufi, Jain or whatever - the important thing being that in the form adopted it does not constrain their devotion to the possibilities of an ever-expanding sexual revolution, identity politics- and all the rest of the mainstream Leftism which a non-negotiable core to the modern Greens.
By contrast, the older environmental writers were quite naturally loyal-to, patriotic-about, and focused-on, the good aspects of their locality.
