In the beginning...

In the beginning there was grass. Well, not really grass but a dirt covering of short green plants. I would spend several hours every couple of weeks or so making it shorter with no personal joy what-so-ever. I came to view my lawn with loathing and resentment. The only obvious option was to hire a lawn service which seemed...like a waste of money. I have a hard time paying someone to do something that I can do myself for free. Kelly thought I was nuts.

I began to wonder about the time and money that people put into their yards. I have a neighbor who is doing something to his grass several times a week. He fertilizes it. He aerates it. He re-seeds it. He mows and edges it. Most of my neighbors have lawn services. They roll up about once a week with a truck full of gear and swarm out like ants at a picnic. It's an impressive sight.

As per my idiom, I started doing the research. To be sure, there is no recognized body of knowledge on this subject of which I am aware but I did stumble across the work of Cristina Milesi, a researcher at NASA who has used a combination of census data, satellite images, and aerial photos to create a very interesting picture of the American lawn craze. Every year we burn 800 million gallons of gas in our 50 million (or so) lawn mowers. One of the staggering finds that I came across several times related to the water that Americans use to keep their lawns perfect. Milesi's research (see Could the Grass be Greener? and Looking for Lawns in the links at the end of this article) discovered that we devote more water and land to our lawns than we do to growing food.

Acre-feet of water used in a year in millions

Lawns	59.6
Alfalfa/alfalfa mixtures	14.3
Corn	11.7
Orchards, vineyards, nut trees	9.0
Rice	6.9

Some other interesting facts:

• We spend nearly 10 times more on lawn care than on school books
• In the Western states, up to 60% of a households water is used to keep the grass green
• Of the 18 most commonly used herbicides, seven cause cancer, six cause reproductive defects, eight are neuro-toxic, nine are damaging to the kidneys and liver (This adds up to more than 18 because some fall into multiple categories)
• Americans use more pesticides a year in home gardens than we use in agriculture.
