In this subject, through a combination of theory, practical experiences, and fieldwork, students develop a deep understanding of environmental science and its relevance to both local and global systems including its connection with agriculture.

    Students study the Earth’s interconnected systems and the role they play in sustaining life in natural and agricultural systems. They will investigate the causes and effects of climate change, its impact on ecosystems and biodiversity, while also exploring strategies for mitigation and adaptation. Students will then study ecosystems and biodiversity, students identify various ecosystem types and their unique characteristics. They examine biodiversity hotspots and threats to biodiversity, such as habitat loss, invasive species, and the overarching challenge of climate change. Additionally, students will learn about the issue of pollution and agricultural waste management, studying the types and impacts of pollution on both the environment and human health. 

    A highlight of the subject is the Fieldwork study on the ecosystem health and water quality in the Tarwin River, providing students with a hands-on opportunity to apply their knowledge and investigate local environmental systems.
