Maybe we need to put ourselves in the position of an old person living alone and unable to afford a little man to cut the grass for them. The "environment" has to be about people as well as wildlife.
Fake grass requires more maintenance and expense than other lawn alternatives! Lets stop pretending that anyone needs fake grass. People get it because they like it not because they have to!
Yes the environment is about people too. Peoples health is directly related to the health of the whole ecosystem: you cant pic n chose to only care for one part of it it is all interconnected, like the systems of the body.
If trees/plants are "our" lungs, mud, marsh & soil is our gut! In recent years marsh/mud/non "lawn" land has been seen as a problem to fix/drain/cover! But muddy marshy soil absorbs carbon! Without it we are screwed!
Garden doesnt HAVE to = green lawn!
