Editing The Carbon Cycle (section)

The carbon cycle is understood through '''Balance''' and '''Timescales'''.

'''1. The Short-Term Cycle (The Biological Cycle)''':
This happens every day and every season.
* Plants breathe in CO2 during the day (Photosynthesis).
* Animals eat the plants and breathe out CO2 (Respiration).
* This cycle is fast and keeps the "Living World" running.
* In the summer, there is less CO2 in the air because there are more leaves "Drinking" it. In the winter, CO2 levels rise.

'''2. The Long-Term Cycle (The Geological Cycle)''':
This happens over millions of years.
* Carbon is "Locked" inside rocks (Limestone) or fossil fuels (Coal).
* It only comes out through "Volcanoes" or "Erosion" (natural) or "Mining and Burning" (human).
* Humans have "Unlocked" this long-term storage, dumping it into the short-term cycle faster than the Earth can absorb it.

'''3. The Ocean's Role''':
The ocean is the "Hero" and the "Victim" of the carbon cycle.
* It has absorbed 30% of human CO2.
* But as it absorbs more carbon, it becomes "Acidic," which kills the coral reefs and the tiny plankton that we need for oxygen.

'''The 'Keeling Curve'''': A famous graph that shows the "Breathing" of the Earth. It shows the steady rise of CO2 in the atmosphere since 1958, measured at the top of a volcano in Hawaii, proving that humans are fundamentally changing the planet's chemistry.
