text: Pollution is a big problem in our ecosystem now and days. Many people don't clearly see this and don't take the time to process in how bad its making earth. Pollution has gone up over the years and decades after decades we have tried to stop it. In source two, it says "Paris typically has more smog than other European capitals." Why? Well because of the exaggerated use of cars. They have tried to reduce the usage in order to make their air cleaner and better. They have gotten the idea of limiting car usage by ordering people with even-numbered license plates to leave their cars at home or suffer a 22-euro fine on Mondays. The same would apply to odd-numbered plates the following day. With this new policy, it has shown better air in the city of Paris by Monday. I believe this is a great forced rule. We need to change our ways and work better in making our air cleaner.
