Suppose Pollution in the Ocean<br>A large amount of plastic has been found in the stomachs of dead marine animals in the Pacific Ocean. The plastic was causing digestive issues and leading to death in many cases. The pollution was traced back to a nearby island where a landfill was located right on the shore.
Can we infer that "The plastic pollution in the Pacific Ocean is only coming from the nearby island with the landfill."? Yes, no, or maybe?
