I noticed it too. The company I currently work at let two big lawns grow out this year. At first I was thinking it was just another way to save money for them, but then I asked around a bit and someone revealed to me it was a conscious decision for the environment.
The company is damaging for the environment in a lot of other ways sadly, but I was still happy to see this shift to consider the environment more.
Looks so nice and a relaxing sight too, makes me wish I had a garden. Maybe some day I can do the same.
