While ecosystems face increasing pressure from human activity, science plays a critical role in controlling and minimising harmful effects. This clip explores the role of science and technology in identifying impacts on ecosystems and finding solutions for a more sustainable future. It provides students of biology and other sciences with an excellent overview of this important area of study. Show Less

Every organism lives in an ecosystem. This clip defines and looks at different types of ecosystems, and explores two critical processes that go on within them – energy flow and the cycling of matter. It is ideal for middle to upper level students of biology and other natural sciences. Show Less

Humans have caused massive changes to the natural balance of ecosystems around the globe. This clip examines some of the most dramatic and destructive ways in which people have impacted ecosystems – covering climate change, pollution, deforestation, and introduced species. Middle to upper level biology and other science students will find this an informative and engaging learning resource. Show Less

Our planet has four spheres – the lithosphere, biosphere, atmosphere, and hydrosphere. This clip provides an overview of vital biogeochemical cycles that occur across the four spheres, including the nitrogen, phosphorous, water, and carbon cycles. It is an excellent resource for middle to upper level students of biology and other natural sciences. Show Less

We often ask ourselves, how can I contribute to a more sustainable society? What’s the best thing I can be doing? Eat, Grow, Love travels across the globe to find that permaculture could well hold some of the answers. Six individuals living in very different climates each prove that designing systems that use permaculture principles really can be a solution. Show Less

Tropical cyclones, also called hurricanes and typhoons, cause catastrophic damage when they strike land. When a cyclone’s fury unleashes on population centres, death, injury and wholesale destruction follow. This programme explores the life cycle of cyclones – how atmospheric conditions, ocean temperatures and the Earth’s rotation combine to create them, how they are driven by winds and eventually weaken after moving over land. Show Less

Tropical cyclones devastate people, property and infrastructure. This programme outlines how cyclones are classified across the world, and then examines the impact of Hurricane Matthew on south-eastern USA and Haiti, in 2016. It compares the strategies that wealthy nations, like the USA, employ to protect people and property, and how the lack of resources in a poorer nation, like Haiti, leaves hurricane victims highly vulnerable to death and suffering.

Australia is home to one of the world’s largest, most complex and amazing ecosystems – the Great Barrier Reef. This video explores the reef’s biotic and abiotic features, including coral formation and how changes in abiotic factors affect it; the food chain, nutrient cycle and carbon cycle; and the impact of human activity. It is an excellent resource for middle/senior students of Geography, Biology and Environmental Science. Show Less

The future of the Great Barrier Reef, one of the world’s most significant marine environments, is under threat due to modern industry and agriculture. Featuring interviews with reef experts, including the director of the GBR Marine Park Authority, accredited reef divers and a Reef Guardians cane farmer, this programme presents an outstanding case study of environmental management for middle/senior secondary students. Show Less

Clean water is essential for human existence. However, international requirements are not met by the available supply. This programme examines rising global water demand and some of the serious issues with inadequate and/or contaminated water supplies. Incorporating a range of water management case studies from various parts of the world, it is an ideal resource for students of Geography. Show Less

What distinguishes plants from other living beings? Why are there so many diverse plants? What is photosynthesis? In this video we will approach the world of plants in order to respond to all of these questions. We will learn about different types of plants and their structure, about how they make their own food and discover how they reproduce. Also, we will understand the importance of these living beings for the balance of ecosystems. Show Less

Follow a indigenous environmental campaigner as he introduces you to his rainforest world and explores the threats facing it. This title considers the value of rainforests, both locally and globally in terms of their goods and services. It then explores the impacts of deforestation and the threats from logging, cattle ranching, commercial palm oil production and oil and mineral extraction. Climate change, soil erosion, water pollution, loss of biodiversity, and the impacts on indigenous communities are all considered. Show Less

Ecuador needs to exploit the Amazon's resources to develop. Leaving it untouched is not an option. This programme looks at the challenges of achieving sustainable management in the Amazon. It explores the political and economic factors that contribute to sustainable management and the role of businesses, governments, indigenous communities and NGOs. Examples include eco-tourism, bio-reserves and conservation, community projects and sustainable agriculture. Show Less

Let a drone take you on a visual journey through the extraordinary biodiversity of the Amazon rainforest, providing fantastic examples of adaptation, stratification and competition. From the forest floor to way up in the canopy, this title explores the tropical rainforest's distinct biotic and abiotic characteristics and the conditions that help create this biodiversity hotspot. Climate, soil profile, nutrient and water cycle, are all considered, as is their interdependence with flora and fauna. Show Less

What causes rain, snow, or a hurricane? The weather. In this video, we will learn about weather and its elements, including how these elements combine to produce atmospheric phenomena. We will also explore the difference between weather and climate, the different climate zones in our planet, and the importance of observing and predicting them both in our daily lives. Show Less

Changes to the natural equilibrium, from prolonged droughts to oil spills, highlight the delicate balance between living things and their environment. This video presents the fascinating world of ecosystems to students. It explains the flow of matter and energy within an ecosystem, the relationships between species that live in the same habitat and the importance of the environmental characteristics of the different types of ecosystems, such as the forest, the ocean and the city. Show Less
