Whenever I see topics about carbon and carbon IV oxide I tend to pause a bit and observe a minute of silence for my country. Automobile emission is one of the leading agent that causes the imbalance in nature. Many developed country don't allow cars that have not gone for emission test and have some degree of safety to ply their roads.
Whenever I'm stuck in traffic, I just pity myself cause I know I'm drinking carbon like water.
