If I were to ask you to name the most irrigated crop in the United States, what would your answer be? Don’t go google it, just answer.
If you’ve ever driven across the midwest in the summertime, you can’t help but notice the acres and acres of corn, wheat and soybeans. But if your answer to my question was one of those three crops, you are incorrect. In fact, if you guessed any edible crops traditionally farmed in the USA, you are wrong.
Wondering what it is? It’s your lawn.
Yes, the most irrigated crop in the US is the iconic American lawn. Many Americans are unaware that their 2000 square foot lawn has an estimated monthly water consumption of 556.4 gallons.
It is no secret that across the United States and the rest of the world, water supplies are increasingly under pressure as populations grow. The water table of the United States has dropped hundreds of feet in many locations. It is not uncommon for rivers and streams to go dry for long stretches in various seasons as water is siphoned off for agriculture, industry, and individual residences. Summer water crises have become nearly an annual event in California, Colorado, Georgia and other regions. Yet every summer Americans pour millions of gallons of water into the ground in order to have green grass.
To put this all in perspective, let’s play a little game of Lawn Trivia.
Question: How many gallons of gas are used every year in lawn mowers?
Answer: 800 million gallons of gas are used to cut the grass short after it was watered to make it tall.
Question: What produces as much air pollution as 43 new cars being driven 12,000 miles?
Answer: A traditional gas-powered lawnmower.
Question: The Exon Valdez oil spill in 1989 dumped 11 million gallons of gas into Prince William Sound off of Alaska. What spill last year was larger than the Exon Valdez?
Answer: The 17 million gallons of gasoline spilled incidentally every year while Americans fill up their lawn care equipment.
I could go on and list the 32 common pesticides used in lawn care and all their potential threats or the contaminated waterways from run off of residential lawns. But I won’t. I won’t because my objective is not to simply criticize and destroy the iconic American lawn. No, my desire is to question the wisdom of using our resources to produce a green space that is neither natural nor sustainable.
Imagine with me a street with lawns that contained native plants (which don’t require pesticides, fertilizers or excess water to thrive), vegetables, herbs, fruits and more. Instead of vast empty spaces of grass that is rarely used, but heavily labored over why not have a space that produces food and flowers and encourages bio-diversity?
Imagine a yard that had only small portions of grass, but instead of high-maintenance non native species, it had native grasses that required little maintenance. Imagine mowing the remaining grass with a rotary push mower.
Consider the results:
- cleaner air and water.
- Less energy and cleaner energy.
- Less consumed resources.
- More time free to enjoy green spaces instead of just maintaining them.
- Increased food supply.
- More wildlife and biodiversity
- Property that reflects one’s character rather than one’s conformity
This is possible. I know because I have decreased my grass by 50% over the last few years. My landscape consists of native plants, edible plants, vegetables, herbs and flowers. I use a rotary mower and an electric trimmer.
Let’s start working together to create a world where green spaces aren’t just spaces that are green.
