Identifying Causal Assumption Flaw in Pollution Argument

In a city known for its high air pollution, a local politician proposed a ban on all plastic bags, claiming that this measure will significantly improve air quality. The politician argues that reducing the use of plastic bags will lead to less litter and consequently less burning of waste, thus reducing air pollution. However, many experts in environmental science challenge this assertion, stating that plastic bags contribute minimally to overall pollution compared to other sources.
