Global Climate Change

Back

Covers the greenhouse effect, greenhouse gases, evidence of temperature change, and predicted future effects.

Front

Environmental science studies the impacts of human activities on the environment, including pollution, biodiversity loss, and global impacts like greenhouse gas emissions.

Back

Environmental science is a tool for developing ways to manage environmental impacts for a sustainable future.

Front

Studying environmental impacts requires an interdisciplinary approach involving biology, earth sciences, chemistry, physics, and human population dynamics.

Back

Section I of environmental science covers how it is conducted, scientific approaches, and issues it addresses.

Front

Environmental science examines interconnected systems of living and nonliving components, such as air, water, and minerals.

Back

Section II focuses on biodiversity, ecosystem ecology, and the organization of living and nonliving components in nature.
