Buried away in here is a serious question (perhaps better phrased as, "does vegetation have a right to exist?"). There seem to be a lot of people who unthinkingly believe that it doesn't.

The American writer, Jared Diamond tells an alarming story in his book, 'Collapse: Why Civilisations Fail'. Apparently, in Australia all land belongs to the government and is leased to farmers.
Much Australian land has a layer of salt below the surface and this salt is held in a sort of equilibrium by the native vegetation.
The government made it a condition of agricultural leases that the tenants must clear the native vegetation from the land - and this brought the salt to the surface, rendering it useless for agriculture.
But the government stubbornly continued with its land clearance condition. Worse still, during the latter part of the Twentieth century, the value of Australian agriculture to the Australian economy went into decline whilst tourism became more important.
One of the most significant regions for tourism is the Great Barrier Reef. But, as a result of the land clearance the Reef was being damaged by salty run-off into the ocean. According to Diamond the policy of land clearance is being changed now - but almost too late.

The folly described above is not unusual and, undoubtedly White Australians brought their almost atavistic 'hostility' to vegetation with them from Europe (OK, the UK!).
We all know about deforestation and how it is now generally thought to be a 'bad thing' - but still it goes on, all over the world, and the more it is deplored the faster it seems to happen.

The other day I went for a walk near my home in the suburbs of a big, Northern UK city. I walked across an area of sports pitches, several acres in extent. It was a Sunday afternoon, at the height of the football season, and there was not a person in sight - let alone a 'sports person'. The area was one vast mono-culture - probably Perennial Rye Grass. All 'native' vegetation was long gone. And I think that there are powerful forces at work in our society and in the wider world who believe this to be wholly a good thing - complex and varied eco-systems are 'untidy' and 'anarchic' and must be either rigidly controlled or ruthlessly exploited.

We are now beginning to get an inkling of where this sort of thinking leads - but I suspect that it will continue unabated until it is far too late for us and for the world's ecosysytems.
