What a perfectly hideous idea!
Why on earth would you? Why would anyone buy an artificial lawn for a space where a real one would grow. Oh, yes, laziness and a complete disregard for nature. Only allowed for football pitches, completely shaded areas and event stands!
Not would they stop any birds or wildlife coming to your garden, but they are quite possibly toxic and dangerous…

Why would anyone want to stop this sort of visitor, a mistle thrush listening for his dinner…..
But of course, far worse is that if you don’t have a lawn, then you can’t instruct your other half to mow it half naked. And thats a crime.
