Reasons to Abandon 1950's Style Grass Lawns

Some interesting facts for parties! One-liners to help make the point that grass lawns are passé!
• According the US Environmental Protection Association, a gas-powered push mower emits as much hourly pollution as 11 cars and a riding mower emits as much as 34 cars (see Small Engine Rule to Bring Big Emissions Cuts).

• Lawn and garden equipment emits 5% of the volatile organic compounds (VOCs) in the US, which cause health problems and contribute to ozone formation.

• A gas mower emits as much hydrocarbons in one hour as a car driven 100 miles. (see EPA pdf)

• Mowers in the US use 580 million gallons of gas per year.

• 40-60% of nitrogen from fertilizer runs off or leaches away, ending up in ground or surface water, including wells.

60-70 million birds die from pesticide poisoning each year in the US alone.

• In the US, 30 percent of water consumed on the East Coast waters lawns, 60 percent on the West Coast. (go to this site for tips on saving water! )

• A 2001 Toronto Staff Report (PDF format), reported that using a commercial leaf-blower for one hour generated "498 times as much hydrocarbons, 49 times as much particulate matter and 26 times as much carbon monoxide" as a then newer-model car.

• Close to 70 million pounds of pesticides (including herbicides) are applied to US lawns each year. This is approximately ten times the amount applied to American farmland, acre for acre.

• As of 2004, about 70 million tons of fertilizers were used on US lawns a year.

• A Toronto Public Health Report on lawn and garden pesticides (PDF format) claims that between 2004 and 2006, almost half the homeowners in Toronto used pesticides on their lawns.

• The Virginia Cooperative Extension in its publication "Nutrient Management for Lawn Service Companies," states that some fungicides and pesticides can kill 60 to 90% -- or more -- of the earthworms where they are applied.

• Between 30 and 40 million acres of land in the U.S. are devoted to turf grass (see Curbing the Lawn)

• Americans collectively spend big bucks -- about $40 billion annually -- on seed, sod and chemicals.

• The top four crops in terms of acreage in the United States today: Corn, Wheat, Soybeans and Grass Clippings.

• And finally, this from me, mowing kills many beneficial caterpillars, spiders, lizards and other small creatures we are sharing our yards with.
