Jeremy Clarkson decides to become a naturalist. 'In just 30 years, insect numbers have dropped by 25% and they're still falling. Without insects, all life on Earth ends. Everywhere where insects like to live is disappearing and I've decided to do something about that. My plan is to make my hedgerows, my valleys, my woods, and my streams more attractive to creepy crawlies. In essence, I am going to leave chunks of the farm completely alone. I'm going to put Mother Nature in the driving seat. It's a process called wilding.'

Brian takes a fresh look at the concept of gravity, revealing it to be far more than just the force that makes things fall to the ground.

As Covid-19 puts Britain on lockdown, Jeremy Clarkson suddenly finds that his biggest worries aren’t all related to the upcoming lambing season. 'If you're involved in food production, you are key worker. We're gonna save the nation!... I've smoked a million cigarettes and I've had pneumonia. If I get it , there's not a lot of hope... Am I panic buying? I bought five tins of sardines the other day'.

The Namib Desert is one of the oldest deserts and also one of the most diverse. With 50ºC (120ºF) temperatures and half a millimetre of rainfall annually, we see how this is possible. Half the size of Oklahoma, from its Skeleton Coast through the sea of sand to the haze of distant mountains this apparently forbidding desert hides secret water sources.
