Identifying Logical Fallacies in Argumentation

In a recent town hall meeting, a local council member spoke about the importance of improving public transportation to help reduce traffic congestion. He argued, "If we don't invest in our public transit system, we will end up with more cars on the road, which leads to more pollution and fewer people using environmentally friendly options. Therefore, any opposition to public transportation funding is simply a way to promote a less sustainable and irresponsible lifestyle for our community." This statement contains a logical fallacy that weakens the argument.
