Key Idea Earth operates on the same principles of carbon cycling as a biodome. The global atmosphere functions as the abiotic reservoir, while forests represent a massive component of the biotic reservoir.
Section 1
From Biodome to Earth
Earth operates on the same principles of carbon cycling as a biodome. The global atmosphere functions as the abiotic reservoir, while forests represent a massive component of the biotic reservoir.
Deforestation disrupts this global balance. Applying the closed-system model reveals that removing the biotic component (trees) must alter the composition of the abiotic component (air).
Section 2
The Data of Loss
Empirical data demonstrates a strong inverse correlation between forest cover and atmospheric carbon. As global forest biomass decreases, atmospheric carbon dioxide levels rise.
This trend confirms that forests act as carbon storage units. Their removal eliminates a critical sink, leaving more carbon to accumulate in the atmosphere.
