As always when people get a bee in their bonnet, they consider one usage decision matrix as the be all and end all, and declare unilaterally that their opinion is the only possible one, and all others are wrong headed and should be punished. In this case, everyone seems to assume the choice is between a healthy verdant lawn, and a cheap roll of astroturf.
I conceded the arguments for why an artificial lawn isn't ideal. But I'd put forward the following for consideration and suggest it's not as simple as "It should be banned, think of the children!"
1) Due to the UK's obsession with 'neat' gardens, a lawn isn't all that great an ecological paradise anyway. What we all
should be doing is sowing wildflowers and letting it grow much longer. Unless that's your approach, you're not quite the paragon of virtue you might be painting.
2) It's not always a choice between artificial and real lawn. I have two dogs and a child haring around. I persevered with an attempt at lawn for a long time, but my final choice was between bare mud and artificial grass. I'm not sure the amount of 'patch magic' I put down was any better for the environment than some plastic!
3) I keep hearing this stuff about how hot it gets and how dangerous it is. All I can tell you is that during pandemic we set our daughter up with a temperature gun and designed an experiment to keep her busy one hot day. It was significantly cooler than our patio stone, albeit warmer than bare soil in the flowerbeds. I probably still have the table she wrote up somewhere, but from memory the paving stone got up to 50C in direct sunlight, while the turf was in the 30s in direct sunlight. Maybe it depends on how good the product is, or what you've got under it?
For myself, the artificial lawn was the best choice. I'm happy in myself that the one-off ecological impact of it's creation is minor considering it's going to last 20+ years. It's surrounded by flowerbeds with bees and insects buzzing around them, and our front lawns are similarly kept to what I mentioned in point 1 (if, by wildflowers you mean moss, daisies, dandelions and clover. And if you ignore that the real reason I keep it long is because I'm a lazy sod.

)
Just trying to add a bit of balance.

I'm sure many won't agree with the points I've tried to make - but that's life!
