Join us on a whirlwind tour of Australia's diverse natural and man-made environments. We kick off with the Great Dividing Range's impact on rainfall and human habitation, and then dive into the Great Barrier Reef, revealing the impact of global warming on this fragile ecosystem. Next we explore the indigenous connection with Kakadu National Park and Uluru, before examining the significance of the Murray-Darling Basin as Australia's food bowl. We conclude with the gradual erosion of the Twelve Apostles and two of Australia's most significant urban environments - Canberra, the nation's capital, and Sydney, the international face of Australia.

This program focuses on the incredible variety of life on our planet and explores the biological processes at work in communities and ecosystems throughout the globe.
In this program we look at the interactions between the atmosphere, hydrosphere, lithosphere and biosphere at three scales: - Global: latitude and vegetation patterns. - Regional: catchment. - Local: mangroves.
This program presents 4 case studies of sustainable agriculture: - Whole form planning: inputs, outputs, erosion control, soil management, tree planting, water management, and salinity control. - Landcare: Communities banding together. - Permaculture. - Inner city gardens. Show Less
