Including this as it’s a well-sourced article on an Australian site. Plastic pollution affects us all.

Plastic in agriculture may result in toxic soils that repel water instead of absorbing it, leading to potentially catastrophic problems.

Nanoplastic particles in plant roots can impair growth and development by diminishing their ability to absorb water.

Scientists began exploring human tissues for signs of nano- and microplastic only in the late 2010s and early 2020s.

While the long-term health impacts of plastic on the human body are still unknown, it is known to have toxic effects on laboratory animals, marine wildlife, and human cell lines.

Plastic particles in the soil cause increased erosion, dust, and the dissolution of symbiotic relationships between soil microbes, insects, and fungi crucial for plant and planetary health.

Plastic is present in the air we breathe, the food we eat, and the water we drink, and has been detected in various parts of the human body including the lungs, bloodstreams, placentas, and breast milk.
