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.
Well, you can only know so much about your country. However, I am sure Nigeria is not the only one guilty of high carbon footprint. Developed countries might be cutting down on emission from automobiles but be releasing twice as much from industries. Take China for example.
