Lawns do provide space for relaxation and some animals like woodpeckers, but most are vanity projects. The market is estimated at about $3 billion per year. Add in energy costs and the chemicals and we individually pay billions to destroy wildlife. My neighbour sprays dandelions with something horrible despite her husband assiduously mowing it short very 2 weeks. Why – does she hate bees and hover flies?
Environmentalists like to blame farmers, and I assure they contribute to loss of habitat in a large way, at least they are producing food. However the 15-20 million lawn owners are doing their bit to destroy our planet for vanity. The ozone layer was almost destroyed by people using aerosols to smell … often … vile. Vanity again.
