We don't know for sure that there are any asteroids in Orion's Belt.
Quite the tangent but it helps prove my point. Orion's Belt is three star systems an average of 400 light years away from each other. They just
look close together but each one contains countless numbers of asteroids.

And now I am a little aware. Like when I used to go out to have tea, I used to drink tea in a plastic cup, now I try to avoid it, now I drink tea in a nearby cup, because when I come in contact with hot tea, microplastics from plastic cups are tortured which can even cause cancer cells in our body.
Unfortunately, most of the microplastics you consume will come from the water you drink and not from leeching of the container.

Any plastic that ends up in water will be damaged by the energy of constant motion and break apart into smaller pieces. The amount of plastic in the ocean always increases and eventually it loses buoyancy and sinks out of sight. But the images you see of swirling whirlpools of plastic are fake.
