In which John discusses the absolute insanity of front yards. Turf grass is the biggest irrigated crop in the US; we irrigate grass almost exclusively with drinkable water; also, you will be surprised to learn that grass is INEDIBLE. Plus, I dislike mowing the lawn when it is 115 outside.
Lots of people (particularly people who work in the lawn business) will note that turf grass is a carbon sink (particularly if you mow the lawn frequently). This is true, but there are far more efficient carbon sinks that don't require so much water.
