During a recent debate on climate change, a participant argued, "If we allow one company to pollute, then all companies will start polluting, leading to total environmental disaster." This statement implies that the actions of a few will inevitable result in the actions of all. It assumes a direct cause-and-effect relationship between the behaviors of a single entity and an entire group without considering other factors or outcomes.
This reasoning is an example of a logical fallacy. Based on this passage, identify the logical fallacy present in the argument.
