Whether they make you fat, fart, or freak out, microbes play a central role in your life. Right beneath your nose—on your face, in your gut, and everywhere in between—trillions of bacteria, viruses, and fungi are so abundant in your body, they outnumber your human cells. But these aren’t just nasty hitch-hikers. Many are crucial to your survival. Evidence suggests that a diverse microbiome can keep you healthy and, conversely, a damaged one could kill you. NOVA Wonders peers into this microscopic world to discover the fascinating, bizarre, and downright surprising secrets of the human microbiome, including the world’s largest stool bank, which transforms raw stool into life-saving poop pills.

So what does the future of food look like and how will we grow enough food for us all to eat in the years to come? In Tonight’s programme we visit some of the urban ventures that are maximising the use of public space to grow fruit and vegetables and teach the next generation how to farm. We speak to the owner of an indoor miniature farm housed inside a small shop about the new aquaponic technology he uses, and we go 100 feet below ground to see how one entrepreneur is growing high-value salad crops in old WWII bomb shelters, four storeys beneath the London Underground!
