You can probably reduce microplastic consumption, but it is quite a pain and more expensive. Try buying everything at the store not wrapped/bottled in plastic. This does not even work as well as you might think as many things are wrapped in plastic and then presented as if they were not. For example, breakfast sausages in the meat display at my local Whole Foods are wrapped in paper when they give it to you, but come to the store in ~1lb plastic wrapped packages.
