It's for golf courses - there are amazing golf courses in dubai that required genetically modified burmuda grass in a sandy synthetic fertilized substrate. They take huge leaf blowers and cover football fields worth of sand with it, water the HELL out of it, and pretty soon, beautiful grass in the desert.
Grass in the desert is great for everyone, that wants to golf or make money off golfers.
Getting grass where it isn't sustainable is not benevolent.
