Learn on PengiAmplify Science (California) Grade 7Chapter 4: Science Seminar (Case Study: Deforestation)

Lesson 3: Global Implications

Key Idea Scientific analysis connects land use changes to global climate trends. Evidence supports the conclusion that deforestation is a primary driver of rising atmospheric CO₂.

Section 1

Synthesizing the Argument

Key Idea

Scientific analysis connects land use changes to global climate trends. Evidence supports the conclusion that deforestation is a primary driver of rising atmospheric CO₂.

The reasoning is based on the conservation of matter: destroying the organisms responsible for carbon fixation inevitably shifts carbon equilibrium toward the atmosphere.

Section 2

Restoring the Balance

Key Idea

Stabilizing the global atmosphere requires protecting its biological regulators. Conservation of forests preserves the planet's capacity for photosynthesis.

Maintaining large-scale forest ecosystems is essential for regulating the global carbon cycle. It ensures that the mechanism for removing excess carbon dioxide from the atmosphere remains intact.
