In Did Toxic Gas Kill the Dinosaurs?, naturalist Steve Backshall explains how invisible, toxic gas came to be a killer of dinosaurs millions of years ago. In addition to causing lava flows and forest fires, volcanic eruptions also produced fumes that were extremely deadly to dinosaurs. This video is excerpted from BBC’s Deadly Dinosaurs, a documentary series in which host Steve Backshall is on the hunt for the deadliest animals to have walked the Earth — dinosaurs — exploring features of several species and putting their abilities to the test to reveal the raw power of these creatures.
In The Unique Underwater Ecosystems of Submarine Mountains, narrator Sir David Attenborough goes deep beneath the ocean surface, where volcanic eruptions have built enormous submarine mountains — some taller than Mount Everest when measured from the seafloor. These underwater peaks create unique ecosystems, as powerful ocean currents sweep nutrients up their slopes. This influx of nutrients supports vibrant marine communities, including soft corals, whip corals, and giant sponges that filter nourishment from the water. Though these ecosystems thrive in complete darkness, they rely entirely on the energy transported by deep-sea currents. This video is excerpted from BBC’s Planet Earth, a breathtaking documentary series that highlights the natural wonders of our planet.
