In the shadow of Italy?s Vesuvius, a lesser-known volcano rumbles: Campi Flegrei. An eruption could endanger the millions of residents of the city of Naples. Scientists gain new insights into what happened in nearby Pompeii, and dig into the unique geology of Campi Flegrei. How will they know if the ever-shifting ground is reaching a breaking point? And can an innovative eruption warning system prevent Naples becoming the next Pompeii?
The discovery of the Marianas trench was one of the first puzzle pieces that lead to the understanding of the most massive process that shapes the geology of the Earth; plate tectonics and the creation of new crust in the mid-ocean ridges and its subduction under the continents.
Hugh Fearnley-Whittingstall and Anita Rani explore where this gigantic problem is coming from, and what we can all do to try and solve it. Hugh goes on the trail of the plastic that does get recycled Malaysia has become one of the biggest importers of British waste plastics. He travels to Malaysia to try and find out what is happening to it all, and what he sees shocks him to the core. Great piles of unsorted British plastics have been left to rot on illegal dumpsites with much of it sat near split UK council recycling bags.
At a time when the Earth's surface is changing faster than ever in human history, watch cities grow, forest disappear and glaciers melt. In the ever-growing grey of cities one man is feeding thousands of parakeets; in Sumatra a female orangutan and her daughter face life in a forest under threat; while in Tanzania local people use satellites to replant a forest, securing the future for a family of chimpanzees. This is our home as we've never seen it before.
