Very gradually, the "lawn trend" crept into fashion with the almost-wealthy, and those who wanted to appear wealthy.
In today’s economy of dwindling natural resources (like water) and rising prices, a big lawn certainly does not promote water conservation. Of course, this wasn't a concern several hundred years ago. Typically, over half the water a household uses goes for watering the landscape. So a water-guzzling lawn flies in the face of municipal or neighborhood water restrictions, which didn't used to be a concern.
