In How Earth Got Its Water, geologist Iain Stewart explains how Earth's first oceans were born from a rainstorm that lasted hundreds of thousands of years. But that epic downpour only gave Earth half its water — the rest came from space! Scientists crashed a satellite into a comet to uncover how these icy space rocks helped fill our oceans billions of years ago. And the story isn’t over — today, in East Africa, a massive crack is slowly splitting the continent, and one day, it could form a brand-new ocean! This video is excerpted from BBC’s Earth: The Power of the Planet, a documentary series in which Dr. Iain Stewart discovers how Earth's forces can shape nature, species, and even the climate.
In Antarctica and Our Climate, geologist Iain Stewart explains how technology allows us to see the full geography of Antarctica, including lakes that are under ice and huge glaciers that cover islands of rock. Antarctica is formed because we are in an ice age that has lasted more than three million years, with small changes that have a large impact as ice advances and retreats over and over again. This video is excerpted from BBC’s Earth: The Power of the Planet, a documentary series in which Dr. Iain Stewart discovers how Earth's forces can shape nature, species, and even the climate.
In The Amazon Rainforest and Human Destruction, look at satellite images that show how forests across South America are being replaced by farms at a rapid pace. Over two million species of plants and animals live in the Amazon rainforest and many are endangered. This video is excerpted from BBC’s Seven Worlds, One Planet, a series featuring remarkable animal behavior from all seven continents.
In Who’s Your Source?, host Radzi Chinyanganya examines how reporters get their information from different sources and ensure their accuracy. For example, BBC journalists exposed a network of hidden detention centers in Western China where Muslims were detained without a trial. The Chinese government was working hard to keep this story hidden by closely monitoring, and even detaining, journalists. Reporters used satellites to investigate, and they also interviewed Muslims in Turkey who claimed to have been in the detention compounds. They looked for consistency and overlap in their stories. Verifying information from multiple sources helps a journalist assess a story and tell it accurately. This video is excerpted from BBC’s My World, a program created for teenagers eager to learn more about the important stories shaping our world.
In Deforestation and Palm Oil see how satellite imaging has revealed a surprising amount of forest removal across the globe. Much of the deforestation is driven by the demand for palm oil, which is found in many products. Deforestation reduces the number of plants that absorb carbon dioxide emissions and adds to the emissions through burning forests. This video is excerpted from BBC’s Climate Change — The Facts, a documentary that delves into the science of climate change and its far-reaching consequences.
