I could write you a full paper if you like on how this all ties into human health, but its obvious from me you fail to grasp how anthropogenic actions like installing fake grass directly affects our ecosystems and how they directly affect us and how were are dependant on ecosystems for our very own existence.
I'm glad you brought up invertebrates as thought they are an environmental issue and not related directly to our health or existence. FYI Insects and other invertebrates make up 94% of the world’s fauna, the UK alone support nearly 40,000 invertebrate species.
Every single one play a central role in all ecosystem services, pollination of crops ,wildflowers, soil creation, dispersal of seeds, recycling nutrients, natural carbon capture, creating clean water bodies and control pest species and they also assist in wider environmental areas, such as raw materials, flood defence, recreation, carbon storage and even provisions for creating clean atmospheric oxygen supplies.
With out these species there would be no food, no medicines, no clean water etc. The toxicity from plastic lawns also affects all these species and deprives them on habitat and affects their reproductive ability and survivability, which directly impacts all life including humans.
Loss of habitat and pollution is a number of cause of the loss of bee`s, but not fury bumble bees you most likely think of, 90% of the species of the bees in the UK are solitary bees with an estimated 250 species of solitary bee in the uk, that have seen a 52% decline in recent decades (PS Plastic lawns prevent them from mining in the ground and the chemicals releases and Nano plastics also affect them.
Claiming "Injecting stuff into a chicken egg is a totally different scenario." Just proves how scientifically dethatched you are from how every single part of this is tied together and important, Ignorance is bliss I guess.
The bio-accumulation of all the chemicals, micro and nano plastics from plastic lawns and the degradation and destruction they cause to underlying soils they sit upon which can house upto 10,000's of species of bacteria, fungi, amoebae, flagellates, other protozoa, nematodes, earthworms and microscopic insects, all factors into ecology and how ultimately they make our life's far more unhealth and unsustainable.
So to dismiss all this is pure uneducated, ignorance.
