Europe sails to the new world. Plentiful prairie grasses don't suit. American entrepreneurship explodes. English turf seed is imported and gets new names, like Kentucky Blue Grass. The first lawnmower is patented in 1830.
Fertilizers become big business and the war of the weeds is on.
Bomb production is off, but the same petrochemicals that can blow up an enemy camp are now fertilizing our lawns, killing dandelions and fueling our power weapons from mowers to weedeaters. On weekend mornings, the machines play their own obnoxious reville and foul the air before the barbecue grill rolls out. Along with the weeds they kill every living thing in the soil. Earthworms no longer aerate the lawn. Wild seeds never grow there, birds disappear.
