I think fake grass looks absolutely shit and I don’t like the environmental impact but I don’t think that banning it is the solution.

Let’s see some incentives for people that keep their gardens wildlife and eco friendly like a council tax discount.

The environmental impact of actual grass that you keep cut is likely far worse. Preferably, grass lawns are banned generally. The expectation of keeping short grass maintained should die.

So you’d rather concrete jungle over lawns? I feel like if you banned grass lawns that’s what you’d get.

That’s a stupid false dichotomy. Why would those be the only options. Clover is a good low growing grass substitute. You can also grow native pants in most of the space so cutting isn’t required. There are many options that aren’t grass lawns that require a ton of maintenance.
