I don't have a video, but from what I understand is they are small plastics (as the name suggests) smaller than 1mm. Larger plastics pass through your digestive system and are excreted, but smaller ones can pass into the body's internal bloodstream and accumulate in internal organs.

The body cannot cleanse them as they are inert. Scientists are researching their relationship with degradation of bodily functions resulting in infertility, inflammation and other diseases.

This is an issue that will worsen over time as plastic production continues unabated. Because humans are at the top of the food chain, as plastics accumulate in our environment, they will increase in over time in the foods we consume (bioaccumulation, think of plankton absorbing plastics, that are eaten by krill and build up in the crustacean's body, then the krill is eaten by a minnow and because one minnow eats many krill, the proportion of microplastic increases as you move up the trophic chain. That minnow is eaten by a tuna, that is then eaten by a human. That person human will ingest more microplastics.

This is in addition to the plastic present in water, vegetables and grains through contamination of ground and rain water, which isn't removed by basic water treatment. Or the plastics that fray from synthetic clothing, especially under friction and heat such as during washing, and are inhaled.

Recycling of plastics is also a complete non-starter because the the plastic degrades in quality with each reuse before it joins the rest of the rubbish in landfill.

At what point the quantity of plastics in the brain, in particular, causes it to totally stop working goodness knows. A recent report says that the average USA adult has a plastic spoon (that's the spoon itself, not the measurement of the bowl of the spoon)'s worth of plastics in the brain. The longer you can delay this the better. Probably.
