> For example, car tires shed lots of microplastics that end up in eggs or inside vegetables and plants, which absorb them from soil. Last year I moved to a house with a greenhouse and started gardening, and was surprised not only by the amount of plastics used, but by the amount of UV unstable plastics used. - Previous owner used polyester string to tie up plants, which now just disintegrates whenever I touch it. I had to go out of my way to find jute twine. - I bought agricultural fabric to cover plants during spring. I left it at the top of the greenhouse over the summer to provide shade. By autumn it was disintegrating as it was not UV stable. Again I had to go out of my way to buy a UV stable polyester sheet that I will use now.
