What happens to the plastic while on it's journey?
Plastic gets thrown to the floor and falls in the tunnel caused by wind and the runoff is involved because the plastic goes in a order going to the tunnel.
Where does the trash go?
It gets falls down into the beach this is called landform and goes to the water caused by wind
What happens when it's far out?
The plastic gets ripped up called micro plastics caused by sunlight energy.
Finally the Great Pacific Garbage Patch
It goes far out to the ocean where it leads to the Great Pacific Garbage Patch and start's moving by Gyres and the Gyres are caused by wind and moves on the surface.
It get's eaten by fish, turtles etc because they will think it's jellyfish and sharks can eat fish with plastic in it and humans too, this is called BPH and large plastic can wrap sea lions or otters and trap them and can starve to death!
The trash arrives at the Great Pacific Garbage Patch where there is a lot of plastic trash, and animals get caught in nets and it weighs tons and more plastic is traveling there and we need to do something about it and some plastic sinks caused by gravity but is still in the Great Pacific Garbage Patch.
