Fake grass is a habitat and food source for nothing, and damages the soil beneath it.
This may be why my neighbors went with fake grass. They had the soil tested and it had a high percentage of lead. (They have a young child who was still crawling at that time.) They had to remove some of the top layer, IIRC, and put down some kind of protective membrane and then did fake grass on top. So this may depend on where you live. We have concrete in our backyard and bought playfalls (padded tiles that you sometimes see in playgrounds) to place under our playset. Luckily we did not have to deal with lead. We have plants that grow well in shade and a tree in our front yard (meaning, it’s just for looks - our kids can’t play in it.)
