CO2 Emission VS Income per Person

What do you observe?

Here is a enlargement of the graph.



Notice that the CO2 emission and income per person has been continue to rise through out the entire 19th Century. One of the main reason for this is industrialization. Like the Great Britain, America is starting to "industrialize" during the 1800s. Many new industriy were set up and more factories were built. Just like the British, the factories use mostly steam-power engine to increase the effectness of production. However, steam-power engine feeds on coal, which will release large amount of carbon dioxide when burned. Therefore, as more factories were set up, the CO2 emission were also increasing.

Also, industrialization brought prosperous to the United State. Many millionaires were made at that time, and many become rich by investing in industry. For example, Andrew Carnegie of steel industry and John D. Rockefeller of oil/petroleum industry.
