text: Smogs? what are smogs? smogs are grey clouds that hurt is in ways we dont even know. Cars emmit these deadly gases and we dont know it. Cars arent the only one who emmit they clouds of grey smoke, factories emmit this also. Which is not helping our ecosystem at all. In Paris they had an order to help redude this problem. On mondays motorists with even-numbered liscense plates were ordered to leave their cars at home which on the following day people with odd numbered liscenes plates were doing the same thing if they did not follow this ruling they were have to suffer a thirty one dollar fine. This helped alot with the smog.
