Lawns

Jordan Harbinger's podcast episode 901: Lawns | Skeptical Sunday on The Jordan Harbinger Show addresses various environmental concerns related to lawns. Here are some key points discussed:
-
Water Usage: In coastal California, each square foot of lawn requires 28 gallons of water a year. In more arid climates, that number can rise to 37 gallons. This extensive water usage is deemed wasteful, especially when considering that lawns serve no practical purpose other than aesthetic appeal, competing with food crops for water resources 1.
-
Origins and Social Implications: The concept of lawns originated from Italian landscape paintings adored by the British aristocracy. Lawns in the U.S. became symbols of wealth and status, first emulated by early American presidents and later popularized through suburban development post-WWII. These origins showcase lawns as symbols of elitism and classism 2.
-
Environmental Impact: Lawns contribute significantly to environmental damage. They lack biodiversity, leading to monocultures that harm native plants and ecosystems. The fertilizers and pesticides used are also detrimental, contributing heavily to greenhouse gas emissions and pollution 3 4.
-
Pollution: Lawn maintenance equipment like gas-powered mowers and leaf blowers are major pollution contributors. Running a new gas lawn mower for an hour produces significantly more emissions than driving a new car for the same duration. Leaf blowers, too, are extremely pollutant, producing as much exhaust in 10 minutes as a truck driving 235 miles 5.
-
Criticism and Alternative Views: Although lawns are often seen as environmentally friendly because they trap CO2, the emissions from their maintenance far outweigh these benefits. Lawns are also a source of noise and air pollution due to the use of leaf blowers and other maintenance tools 6.
For anyone reconsidering their lawn habits, Jordan Harbinger and his guests suggest rethinking lawn care practices to mitigate environmental harm.
