I know there's a movement around not cutting grass and not trimming hedges and so on which I have to say our local council has enthusiastically embraced to the point that road signs are partly obscured by various shrubbery.
However although this might be lovely for bees (although the absolute benefits are probably limited in the context of the age of industrial farming which no one is doing anything about) it is hell on earth for people with pollen allergies. And is particular hell on earth for people like me who have pollen allergies and a corneal condition.
I've just woken up due to corneal pain and have spent ten minutes pouring eye drops into my eyes and I know it's only going to get worse as summer goes on. The environmental benefits from people failing to tend their greenery in urban areas are negligible while the effects on the people around you can be absolutely brutal. Please, please cut your bloody grass. This is awful.
