In the given set of materials, the main topic has centered on whether the population of zebra mussel, a freshwater shellfish, could be controlled or not. While the author has focused on lack of feasibility of proposed solutions, the speaker in the follow-up material cast doubt on those points by blaming human knowledge.
The first point in the article is that the history of this shellfish spreading in its original habitat, Eastern Europe, obviously proved that it might happen again in North America. However, this was questioned by the lecturer as he stated that if the "ballast water" refilled with the ocean salty water, the dispersion of the mussel would stop.
Moreover, according to the essay, different factors such as its sturdiness, highly reproduction, and lack of local predators led the mussel population to be increased. Nonetheless, the orator discussed that although it might be the case in the beginning of its arrival, some birds fed on it as their food resource.
Last but not least, the writer has stated, since both mussels and fish competed with each other for eating plankton, the fish population decreased. Conversely, according to the lecture, this species provided nutrition for a specific fish, in overall view, this assumption might not be true.
