During this driving project, I decided to do how much CO2 cars make in a year, compared to how much CO2 St. Helens has made since it has erupted in 1980. This was an interesting project to go into. To start with, I found out how much an average car emits per year which is 4.6 metric tons. If you put 1.5 metric tons of carbon into your car, it's going to triple when it comes out of the exhaust pipe since it's being absorbed with oxygen and other molecules. After I got the number 4.6 metric tons, I googled how many cars are approximately in the world. The number I got was 1,015 billion cars. Once I got those two numbers, I multiplied 4.6 by 1,015 billion and got 4,699,000,000. Once I got all the numbers I needed for the cars, I started looking into my volcanoes. I found out that St. Helens has only emitted 10 to 50 million tons of CO2 since it erupted in 1980. I learned that if it wasn't for humans, the CO2 emissions would be stable right now.
