Truth about grass (in the American West) is that it is an extremely serious problem because of the water it consumes. One of these times we are going to exhaust all our aquifers and go bone dry. Land is already beginning, in some places, to sink into collapsing aquifers. Colorado has the lushest, greenest lawns I have ever seen. Even Western Colorado, which is part of the Great Basin. They love those green lawns, in part if Colorado does not consume all that water, it might get consigned to other States, or to Mexico.
