It’s a common saying that elephants never forget. But the more we learn about elephants, the more it appears that their impressive memory is only one aspect of an incredible intelligence that makes them some of the most social, creative, and benevolent creatures on Earth.
In the final episode of the series, Anita Rani investigates the tsunami of single-use plastic that parents pick up in the form of give-away toys. It turns out that McDonald's are the largest toy distributor in the world, handing out over 1.4 billion plastic toys per year worldwide. They claim on their website that they are recyclable, but a visit to Simon Ellin, the CEO of the Recycling Association, makes it very clear that while that may be true in theory, in reality it’s not that simple. Meanwhile, Hugh is in Scotland. He’s learnt that at the same time as the public are trying to reduce the amount of plastics in their lives, the plastics industry has big plans to increase plastic production by 50% before 2040. To find out more, he visits the INEOS factory in Grangemouth, owned by the richest man in Britain, where they produce a staggering 60-70 billion tiny plastic pellets every day.
Earthquakes have always been a terrifying phenomenon, and they’ve become more deadly as our cities have grown — with collapsing buildings posing one of the largest risks. But why do buildings collapse in an earthquake? And how can it be prevented? Vicki V. May explains the physics of why it is not the sturdiest buildings, but the smartest, that will remain standing.
The air around us is not just empty space; it is an integral part of the chemistry of life. Plants are made from carbon dioxide, nitrogen nourishes the soil and oxygen gives us the energy we need to keep our hearts pumping and our brains alive. But how did we come to understand what air is made of? How did we come to know that this invisible stuff around us contains anything at all?
As winter approaches, field teams are finishing up their science for the season. It's the last chance to obtain information for their research on the frozen continent. As most people are preparing to leave, a container ship is on its way in to supply food and materials to the skeleton crew that remains during the cold, dark winter months.
