text: First of all, limiting car usage reduces the amount of pollution worldwide. Reflective and didactic, Robert Fuller's "Paris bans driving due to smog," reflects the amount of pollution that is reduced due to limited car usage. For example, Robert Fuller explains that "...[Last] week Paris had 147 micrograms of particulate matter (PM) per cubic meter compared with 114 in Brussels and 79.7 in London, Reuters found." This statement layers Robert's opinion that car usage can create vast amounts of pollution. If car usage is limited, the amount of particulate matter would decrease. For instance, this theory is created when Robert Fuller states "The smog cleared enough Monday for the ruling French party to rescind the ban for odd-numbered plates on Tuesday."
