Everything in AP Environmental Science is a feedback loop.
Humans alter systems; systems push back. The course is about understanding those loops before the pushback becomes irreversible.
Global Change carries the heaviest exam weight — and answering it well requires you to hold every prior unit in your head at once.
The AP exam places significant emphasis on Global Change, which requires a comprehensive understanding of all prior units. Populations, Earth Systems and Resources, and Land and Water Use also carry substantial weight due to their foundational role in understanding human impact on the environment.
How the course builds
Energy transfer · Interactions between Earth systems · Interactions between different species and the environment · Sustainability
Global Change is where most students hit a wall.
Requires synthesis of all previous units to understand complex global interactions and propose solutions.
Students often lack experience in integrating multiple environmental concepts into a cohesive understanding.
