Quoting Bill Mollison

"...the greatest change we need to make is from consumption to production, even if on a small scale, in our own gardens. If only 10% of us do this, there is enough for everyone. Hence the futility of revolutionaries who have no gardens, who depend on the very system they attack, and who produce words and bullets, not food and shelter."

“. . . every society that grows extensive lawns could produce all its food on the same area, using the same resources, and . . . world famine could be totally relieved if we devoted the same resources of lawn culture to food culture in poor areas. These facts are before us. Thus, we can look at lawns, like double garages and large guard dogs, [and Humvees and SUVs] as a badge of willful waste, conspicuous consumption, and lack of care for the earth or its people.

Most lawns are purely cosmetic in function. Thus, affluent societies have, all unnoticed, developed an agriculture which produces a polluted waste product, in the presence of famine and erosion elsewhere, and the threat of water shortages at home.

The lawn has become the curse of modern town landscapes as sugar cane is the curse of the lowland coastal tropics, and cattle the curse of the semi-arid and arid rangelands.

It is past time to tax lawns (or any wasteful consumption), and to devote that tax to third world relief. I would suggest a tax of $5 per square metre for both public and private lawns, updated annually, until all but useful lawns are eliminated.”

“Order is found in things working beneficially together. It is not the forced condition of neatness, tidiness, and straightness, all of which are, in design or energy terms, disordered. True order may lie in apparent confusion . .

Thus the seemingly-wild and naturally-functioning garden of a New Guinea villager is beautifully ordered and in harmony, while the clipped lawns and pruned roses of the pseudo-aristocrat are nature in wild disarray.

Neatness, tidiness, uniformity, and straightness signify an energy-maintained disorder in natural systems.”
