This book is a celebration of grass - something most of us take for granted. The writing is a joy to read. The book has the quality of the reader being taken on a journey through time, to places long gone, by a guide who wants to share his passion and deep knowledge of grass and its place in British history and culture. In an understated way the author makes a convincing case against the use of artificial fertiliser and in favour of organic farming.
The book avoids brow beating. The author devotes a chapter to the lawn mower and several chapters to the impact of grass on our national sports. Indeed, because "football has always taken on the character from the turf it was played on", grass might become the scapegoat for the decline in our sporting performances. After all, the muddy pitches where youngsters learn to play do not reward skill.
Harvey suggests small changes that might have a profound effect on our environment and on our psyche. He extols the virtues of urban parks. They are shown to reduce stress and act as the city's `lungs', filtering out pollutants. They also have a cooling effect in hot weather. Heat is diverted into evaporating moisture instead of raising the temperature. This is why roof gardens are being encouraged in Tokyo where temperatures are rising four times faster than global warming.
When all said and done, it is the physiology of grass that underpins its place in the world. Unlike shrubs and trees, the growing point in grasses is at the base of the stem, below ground, protected from fire and beyond the reach of the grinding molars of herbivores. This lends grasses a genetic advantage, equivalent to our articulated thumb. Fire and grazing animals damage the growing points of trees and shrubs, preventing cell division and growth, and leaving the way open for grasses. For me, the best part of this excellent book is when Harvey discusses Darwin's theory of natural selection in the context of different grass species. He includes convincing metaphors from economics, fables, and warfare to make his points.
The author explains how mismanagement of grassland leads to infertility. For example, while "the prairies once gave their bounty free of charge, courtesy of sun and soil....", now 70% of America's grain goes to fatten the 45 million cattle that replaced 50 million bison. Apart from resulting in fatter meat loaded with cholesterol, it also depends on heavy subsidy and fertiliser.
It is perhaps ironic that British farmers also turned to fertilisers to compete with cheap imports from the prairies. The price for increasing yield has been the disappearance of most meadow flowers from 85% of British grassland. Fertilisers have also degraded the humus and upset the soil ecology, decimating our more visible wildlife. However, there is hope. Water meadows and the use of clover are just two examples of natural solutions to past infertility. Besides, while books of this calibre are being written, there is a good chance that current and future generations will learn from and correct the mistakes of the past.
