How lawns use more water than people think they are choosing
A green lawn is a large leaf area transpiring in the sun, not a small choice.

From the opening
A lawn uses more water than people think they are choosing because a green carpet is a large leaf area in the sun, transpiring whenever it is growing. The sprinkler is the visible choice, and the transpiration is the continuous one, and it scales with the area. The opening covers transpiration across a large leaf area, green growth versus summer dormancy, and depth times area is the volume.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
