Siužetinės Linijos Tekstas
- 4.5 billion of years ago the atmosphere was primarily composed of Hydrogen and Helium.
- The oxygen levels were about 15 percent to around 19 percent.
- At this time dinosaurs breathed air that was far higher in oxygen than ours and lived in far more flammable woods and grasslands than we do.
- Carbon dioxide levels in the atmosphere during the ice age were extremely low, at around 180 parts per million.
- For awhile I hanged out here with the atmosphere that is filled with 21 % oxygen and 0.04% carbon dioxide.
- At this time I met people which aren't very nice sometimes because they kick me around.
- Nowadays the carbon dioxide in the atmosphere is rising and is surprisingly half way to unsafe levels for humans
- After being washed down to the ocean, I got broken down into tiny rocks in the sand. If only humans would stop burning fossil fuels and start using green energy so carbon dioxide levels could decrease.
