text: Limiting car usage helps to reduce pollution in the world. An example of this is Paris banning driving do to smog, yet getting rid of the ban cause eventually the smog cleared up (Source 2). This provides proof that by limiting car usage we can reduce and prevent some pollution. Additionally by limiting we'll be making the world a lot less polluted especially if people were to follow Paris's example and put a temporary ban on cars to reduce pollution. And considering just Paris having and it helping them reduce pollution, it'd be safe to say having a temporary ban on all cars around would have a huge impact on the world  and the pollution.
