This clip provides a number of different examples of how mangroves and tropical rainforests can be sustainably managed. Examples from the Sundarban mangroves and Amazon rainforest include: eco-tourism, controlled logging and the role of international treaties and agreements, creation of nature reserves and national parks, developing more sustainable agricultural practices and creating alternative livelihoods. The benefits and challenges of the different approaches are considered. Show Less

This clip compares how tropical rainforests and mangroves have adapted to their environments. We explore how despite sharing the same climatic conditions, mangroves face an additional challenges because of their coastal location. We see examples of how rainforests have adapted to their warm, damp environment including: the forest structure, drip tip leaves, lianas, buttress roots, epiphytes. This is then compared with how mangroves have adapted to survive in brackish water and waterlogged soil, i.e. through root adaptations. Filmed in a variety of rainforest and mangrove locations around the world. Show Less

This clip considers the functions or both rainforests and mangroves in the environment. The importance of rainforests as water catchment, climate regulator, green lungs of the earth, carbon store and biodiversity hotspot are all considered. We then look at how mangroves protect coasts from cyclones, waves and floods, clean our water, store carbon and create biodiversity hot spots including important habitats for nurseries for the world's fish stocks. Filmed in a variety of rainforest and mangrove environments, including the Amazon and Borneo rainforest and the Sundarban mangroves. Show Less

This clip considers the economic, environmental and social impacts of overusing mangroves and rainforests, including potential for economic development, deforestation, loss of habitat and biodiversity, environmental pollution, increased risk of flooding, soil erosion, impact on climate, loss of natural resources, loss of indigenous lands and livelihoods. Footage from the Amazon shows the impacts of rainforest deforestation from logging and palm oil plantations. Footage from the Sundarban mangroves shows the impacts of over fishing and shrimp farming.

When it comes to fire safety in the workplace, we might be tempted to think that it's not our concern, or that there's plenty of other things to worry about—until it's too late. However, it's everyone's responsibility to prevent fires. That means we all have an important part to play in identifying and minimising the risks. Show Less

Safety is more than warning signs and handrails - it is an attitude of the mind. There are many traps for those whose attitude is amiss. Whether you're surviving the zombie apocalypse or just surviving daily grind of the office, the consequences of having the wrong attitude to safety can be deadly! In this video, you'll meet the Zombusters team and see how complacency, rushing, distractions, and unfamiliarity can get the better of us, and how to avoid these mind-traps. Show Less

In the sea life is everywhere, but five habitats are like underwater cities. They are coral reefs, mangroves, salt marshes, sea grass beds and kelp forests. They provide safety, food, and a nursery for the young of many species. Yet they are in critical danger because we humans are rapidly destroying them. This programme seeks to explain why these five habitats are very important to life in the sea and to point to the fact that they are all in decline. They are being damaged by human activity... some are being cleared away for ports or housing, some are damaged by trawling nets or dredge silt, as well as pollution, overfishing, or the slow but undeniable outcomes of global warming... to name only a few of the reasons. We need to try and stop this worrying trend. Show Less

This programme is about seawater. It is the most important liquid on Earth, not only from its sheer volume, but also because it has remarkable qualities. A few of them, like buoyancy, are common to all liquids - but seawater is also the cradle of life. Three key factors of water underpin life in the sea: water’s dissolving power, its tendency to keep a stable temperature, and its transparency to light. This programme explains the mechanisms and the outcomes of these key facts—and other things—that make seawater both weird and wonderful. Show Less

Rivers wield transformative power on the landscapes through which they flow. This video takes viewers through the upper, middle and lower courses of the longest river in the UK, introducing key terms such as drainage basin, tributary, erosion, discharge and estuary. Real footage paired with informative diagrams makes this essential viewing for secondary geography students. Show Less

The calm appearance of a river in the middle course hides the fluvial processes at work under the surface. This video explains how landforms such as meanders and billabongs, or oxbow lakes, are created through erosion and deposition and shows viewers the rapid transformative power of floods. Real footage and informative diagrams makes this essential viewing for secondary geography students. Show Less

As a river comes to end of its journey in the lower course, distinctive fluvial landforms emerge.
